Florida Geological Survey Biennial Report 19 Florida Geological Survey at a Glance Affiliation The Florida Geological Survey is a bureau within the Florida Department of Environmental Protection, Division of Technical Services. Mission The mission of the FGS is twofold: First, to collect, interpret, disseminate, store and maintain geologic data, thereby contributing to the responsible use and understanding of Florida's natural resources; and second, to conserve the State of Florida's oil and gas resources and minimize environmental impacts from exploration and production operations. History The Office of State Engineer and Geologist was created by the state legislature in 1852. "General" Francis L. Dancy, an engineer, occupied this position until 1855, when it was abolished. In 1880, Alabama State Geologist Eugene Smith noted the presence of phosphoric acid in a sample of Flbrida building stone. This discovery of potential commercial phosphate commodities in Florida led to the establishment in 1886 of a new State Geologist position. Dr. John Kost, a medical doctor, was appointed to the post by then Governor E.A. Perry. The position was again abolished by the legislature a year later. For the following two decades geological explorations in the state were conducted by the USGS and private companies. Legislative action to create a permanent Florida Geological Survey was finally proposed in 1903 and passed in 1907. The Survey began in 1907 with Dr. Elias Sellards as its first State Geologist. It was housed in an unused committee room of the old Capitol building, left vacant by the recently adjourned legislature. The Survey subsequently occupied four other locations around Tallahassee before moving into its current offices in the Herman Gunter Building on the Florida State University campus. Today the FGS is the state's primary earth system research and data collection agency, providing information to other agencies, academic researchers, planners, and the citizens of Florida.

(photo by Tom Scott) iv FOREWORD The biennial years 1995 and 1996 were again very busy and rewarding for the Florida Geological Survey (FGS). The Survey has now settled into its place in the recently reorganized Department of Environmental Protection (DEP). The FGS continues to be administratively within the Division of Administrative and Technical Services. One change since two years ago is that the position of Deputy Director of Technical Services has been deleted by the Department. The Survey Chief now reports directly to the Executive Services Director. Other organizational aspects of the Survey's structure remain unchanged. During the 1996 Legislative Session several significant actions occurred which directly impact the workings of the FGS. First and most significant, was the passage of a revision to Chapter 377.075 Florida Statutes (as Chapter 96-323, Laws of Florida) which is the law defining and authorizing the Florida Geological Survey. The amended wording provides greater clarity and specifically defines the "State Geologist" position as the director of the Florida Geological Survey (which heretofore was only defined by a job description within the Department of Environmental Protection) and requires the director to be a Florida licensed geologist. The FGS is directed to conduct field and laboratory investigations and to consider scientific, educational and economic questions related to the geology and hydrology of the state. It is further directed to maintain a comprehensive research library and statewide repository for well cuttings, cores and related surface and subsurface samples and data. The FGS is also designated to act as a clearinghouse for other agencies funded by the state that propose revisions of geologic interpretations and nomenclature. Further, new language requires the FGS to collect and maintain data on the economic mineral industry of the state and to designate "state geological sites" or "state invertebrate paleontological sites" for those areas determined to be of great and continuing significance to the scientific study and public understanding of the geologic history of the state. A second important part of that bill dealt with Oil & Gas related issues. These included: a statutory definition of the Big Cypress Swamp Advisory Committee; authority to issue permits for the injection and recovery of any natural gas for temporary storage in subsurface reservoirs; horizontal well completions and associated spacing adjustments; and allowing for geographical positioning system (GPS) coordinates to be used for drilling unit control. In the same act, Chapter 211, F.S. was also revised to provide short-term tax abatement for selected oil and gas production. In other actions passed by the Legislature, numerous trust funds were eliminated by consolidation or redefinition. Included in this action was the elimination of the Petroleum Exploration and Production Bond Trust Fund (PEPBTF). The functions and overall purpose of the PEPBTF however, continue within the Minerals Trust Fund (MTF). The MTF is the source of funding for the FGS and the Bureau of Mine Reclamation. Funds are derived from a percentage of severance taxes collected from selected economic mineral production throughout the state. During the last two years the FGS has continued its productive and efficient relationship with several other state and federal agencies to provide applied geoscience assistance to contribute to the solving of today's environmental problems. We now have contracts or cooperative working agreements with twelve different agencies or programs to supply geoscience interpretations or to assist with geologic and hydrogeologic field data collection. These contracts totaled over $511,000.00 at the end of 1996, an all- time high for the FGS. The FGS typically assigns a professional geologist on staff as a principal investigator (PI) on a project, and uses the additional contract funds to hire geology graduate students, support field travel and or lab work. The cooperative relationship we have with the Florida State University Geology Department to share laboratory equipment, research facilities, faculty expertise, and utilize the graduate student population as a "work study program," clearly provides an efficient cost/benefit to the public and taxpayer. In recent years, graduate students and faculty from the University of Florida, the University of South Florida, and the University of Miami have also been involved in various research projects. The Survey has re- emphasized the educational component of our mandate during these last two years. Recently completed is the Florida Geology Educational Video Project, titled: Florida's Geology Unearthed. This project, funded jointly by the FGS and the Florida Advisory Council on Environmental Education, includes a one hour video (broken down into five segments with built-in breaks), selected FGS educational publications, and an "Educator's Guide" with learning activities to assist middle school teachers with teaching the material and to expand on the main themes. The project is designed to inform and stimulate students in a variety of topics related to earth sciences, natural resources, environments and ecosystems. Another educational project recently completed is a poster displaying and describing "Earth Systems" as the foundation of Florida's environment and ecosystem understanding. Survey staff have also participated in Department-wide workshops to teach the concepts of Ecosystem Management for the 4400 staff of the DEP. Over thirty lectures teaching the fundamental nature of understanding that the solid-earth is the foundation of our environments have been given. Members of the FGS have also been involved in making significant contributions on the national scene as well as within the state. Walt Schmidt served as the President of the Association of American State Geologists (AASG) during the 1995-96 fiscal year. In that capacity he was an invited participant in the AGI/U.S. Department of the Interior, Societies President's Workshop to make recommendations to Congress and the Secretary of the Interior regarding the merger of the National Biological Service into the U.S. Geological Survey. He also served on the Peer Review Panel of the STATEMAP component of the National Geologic Mapping Program in 19.96. In addition, Dr. Schmidt represented Florida at the joint AASG/USGS Workshop on Domestic Mineral Statistics, and authored testimony in support of the reauthorization of the National Geologic Mapping Act of 1992 (H.R. 3198), to the U.S. House of Representatives Subcommittee on Energy and Minerals Resources. Dr. Rodney DeHan was elected President of the Ground Water Protection Council (GWPC), and also has been representing Florida on the Intergovernmental Task Force on Monitoring Water Quality (ITFM). Dr. Thomas Scott served as president of the Southeastern Section of the Society for Sedimentary Geology (SEPM). Research projects during the 1995-96 biennium have again been dominated by hydrogeologic studies. In conjunction with the various Water Management Districts several aquifer characterization studies have been initiated. Staff have also been involved with some of the many projects underway by both state and federal agencies to better understand the Everglades and Florida Bay environments. This basic system understanding is a precursor to the eventual conservation of the ecosystem of the entire area. Several physical-plant laboratory upgrades have also occurred during the last two years. One of two bays in the basement of the Gunter Building has been converted to a core preparation, description, and sedimentological preparation facility. A core cutter has been designed and built, a drill press corer has been constructed, and a new state-of-the-art balance has been acquired. The FGS permeability lab added 24 new falling head permeameters bringing the total to 44. During the 1995-96 fiscal years the Survey had its staff computer stations networked into the main DEP system. Word- processing and database software was converted to Microsoft Office products. The FGS now has access to, and is accessible through the Internet with all staff now having e-mail addresses. The FGS world wide web homepage has recently been completed and is now up and running. Information on the Survey programs, data archives, newsletters, List of Publications, selected reports, and other information is now hot linked to the homepage. The staff of the Florida Geological Survey continue to perform in an outstanding, professional way. We are very fortunate to have a dedicated staff with such low turn- over, which develops important corporate memory and state specific experience. Walt Schmidt Dr. Walter Schmidt, State Geologist INTRODUCTION The Florida Geological Survey (FGS) is located on the campus of the Florida State University (FSU) in the Gunter Building, adjacent to the university's Geology Department. The FGS has a staff of 56: 18 professional geologists, one senior research scientist, 16 research assistants, four research associates, four engineers, one environmental specialist, a professional driller and drilling assistant, an administrative assistant, a librarian, and support staff. The FGS Offices, Gunter Building, Tallahassee. Research facilities at the FGS include a geological research library, a sample repository, and laboratories. The library contains an extensive collection of state and federal publications, periodicals, and references. The sample repository holds cores and well cutting samples from more than 17,000 wells (both onshore and offshore). Laboratory facilities include a permeability lab equipped with 44 falling-head permeameters; a sedimentology lab containing diamond rock-saws, drill press corer, and core saw for core processing, Ro- Taps, ovens, and balances; sample preparation equipment for clay mineralogy, organic /carbonate content and micro/nannofossil studies; and an ETEC Scanning Electron Microscope with a Kevex semi-quantitative probe. Field equipment includes a trailer- mounted auger rig, a Failing 1500 drill rig for continuous diamond coring, a truck-mounted Mobile Drill Rig with wire-line coring capability, various pickup trucks and four-wheel drive vehicles, and three boats used in coastal research projects. The FGS also has cooperative agreements with FSU's Geology Department to use an x- ray diffractometer, an x-ray fluorescence spectrometer, an atomic absorption spectro- meter, and an alpha spectrometer. RESEARCH AND REGULATORY PROGRAMS GEOLOGICAL INVESTIGATIONS SECTION The -Geological Investigations Section is involved in a wide range of research covering both onshore and offshore areas of Florida. New statewide geologic and geomorphic maps are in preparation. The geologic map depicts the distribution of geological units throughout the state and provides an invaluable aid in the environmental decision-making process. Such a map provides first approximation solutions to numerous environmental and management related problems. The geomorphic map delineates the distribution of landforms across the state. These two types of maps provide powerful tools in defining problems relating to ground water, waste disposal, geological hazards, and mineral resources. Geologists in the Geological Investigations Section are also involved in various applied and basic research projects designed to acquire geologic data useful to intelligent growth planning and effective resource management. The Plio-Pleistocene sediments in southern Florida, important as aquifers and as the foundation for the burgeoning growth in that area, are being investigated and mapped in cooperation with the United States Geological Survey (USGS). Staff geologists are collaborating with the USGS on the investigation of the Everglades and Florida Bay, both sensitive ecosystems whose underlying geology has played a significant role in their development. Studies of the geological history of the deep subsurface Paleozoic and Mesozoic rocks in northern peninsular Florida and the panhandle are also underway in order to better understand the state's petroleum reservoir rocks. Additional studies currently in process include the geochemistry of peat in Florida, research on the state's extensive caves, and the study of geology of Taylor County.

The section also consults with other government agencies since the knowledge of regional and local geology of a given area is fundamental in the evaluation of numerous environmental problems. Geological Investigations responds to inquiries regarding aquifer recharge and contamination, geologic hazards, geologic mapping, and problems related to community planning and development. The group prepares detailed lithologic logs for wells that are on file with the FGS. This information is added to the Survey's computerized data base which currently contains logs for approximately 4,000 wells. This data base and the programs designed to manipulate it are currently used by other governmental agencies and a number of private firms. MINERAL RESOURCES and ENVIRONMENTAL GEOLOGY SECTION Florida ranks first in the nation in the production of phosphate rock and ninth, nationally, in non-fuel mineral value. The Mineral Resources and Environmental Geology Section maintains communication with the mineral industry in Florida and publishes biennial status reports related to industry activity. The section also provides mineral resource assessments on specific land parcels to the Department's Division of State Lands on an as-needed basis. Petroleum is produced from a total of 12 oil fields in Florida. Seven fields are productive from the Lower Cretaceous Sunniland Formation in southern Florida; five are productive from the Upper Jurassic Smackover Formation and Norphlet Sandstone in the western panhandle of Florida. The Mineral Resources and Environmental Geology Section prepares biennial reports on Florida's petroleum production and exploration. The biennial report covering 1994 and 1995 was completed in 1996. Another aspect of the group's work with non-fuel minerals involves the preparation of county mineral resource maps. County mineral resource investigations were initiated to assist counties in the preparation of this component of the comprehensive land-use plans mandated by the state legislature. The goal of these studies is to identify potential mineral resource areas and present the results in a format appropriate for use by Florida's planning community. The results are published as 1:125,000 scale maps with supporting text and figures. The maps present the major mineral commodities for use as a guide to resource location. The supporting text discusses the county's geology and geomorphology as well as specific mineral commodities accompanied by inset maps and geologic cross-sections depicting the near- surface sediments. A total of 19 of these county investigations have been completed and two additional reports are in preparation for Escambia and Jackson Counties. Nearly 900 new residents move to Florida each day. This phenomenal population growth stresses the state's environment and its resources. Geologic information is essential for environmentally responsible land-use planning and resource and ecosystem management. Recognizing this, the section began a series of special environmental reports that target specific rapidly-growing urban areas. These reports integrate cultural, climatological, geological, and hydrological data to illustrate the importance geology plays in land-use planning. Graphics are used to present data and geologic concepts in a format that can be readily used by the lay-public, scientists, and planners. The first two reports in this recent series cover the cities of Ocala and Gainesville. A third report on the Pensacola area is in preparation. Environmental geology and hydrology are discussed, emphasizing topics relating to water resources. The hydrologic cycle, karst geology, surface water, and the underlying aquifer systems are analyzed in detail, establishing the relationships among them. Recommendations for protection of these resources through appropriate land-use planning are also presented. Over the years, the FGS has recognized the need for a geologic educational and public outreach program. Although all members of the FGS professional staff participate in this program, it is coordinated through this section. Outreach activities include lectures and presentations to school groups at all levels and civic and professional organizations, participating in science fair judging and school mentoring programs, and publication of educational materials. Production of a new educational poster, Earth systems: the foundation of Florida's ecosystems, was completed in 1996 in cooperation with the FGS Geologic Investigations Section. The poster includes maps, block diagrams, and text which describe and illustrate the importance of geology and geomorphology in shaping ecosystems. The poster demonstrates the interaction of the solid earth aspects of earth systems (geology), the atmospheric aspects .(meteorology), and the aqueous aspects (hydrogeology and hydrology) in forming specific ecosystems. The section also assisted in the production of the Florida Geology Education Video which is described in more detail in the Special Projects section of this publication. After the Florida Sinkhole Research Institute lost its funding support, its computer database and archive files were transferred to the FGS. This section has done extensive reformatting and updating of the data, in order to make it available to the public and private sectors. An index to the sinkhole database was published in 1994 and will be updated periodically. In addition, the section handles requests for sinkhole data and coordinates requests for individual sinkhole inspections. In 1991, the FGS organized an informal Coastal Research Group (CRG) under the aegis of the Mineral Resources and Environmental Geology Section. This was in response to the long standing recognition of the need to establish a marine and coastal geology program which would generate resource maps of offshore areas, as well as submerged lands (bays and estuaries). Investigations of geological processes affecting coastal environments and ecosystems would be included in such a program. These studies would complement the state's ongoing efforts to control coastal erosion and manage fragile coastal environments. This program is discussed in further detail in the Cooperative Programs section of this publication.

Freedenberg) OIL and GAS SECTION The Oil & Gas Section regulates hydrocarbon exploration and production in Florida and within state waters pursuant to Chapter 377, Florida Statutes and implementing Rules 62C-25 through 30, Florida Administrative Code. The Section's primary responsibilities are conservation of oil and gas resources, correlative rights protection, maintenance of health 9jd human safety, and environmental protection. These concerns are addressed when permit applications are reviewed and permit conditions are enforced by field inspection. The section's main office is located in Tallahassee and field offices are located near producing fields in northwest (Jay) and south (Ft. Myers) Florida. The section's key activities include permitting geophysical, drilling, and transport operations, inspecting field activities, tracking activities by the use of production and other reporting forms, Florida's Oil Fields SCALE 0 10 20 MILES S 10 20 30 KILOMETERS -N- EXPLANATION 1 ( A IVE OIL FIELD 0 INACTIVE OIL FIELD LOCATIONS SOUTH FLORIDA OIL FIELDS NORTH FLORIDA OIL FIELDS SOUTH FLORIDA OIL FIELDS J. Lloyd 1997 enforcing financial security requirements, and maintaining a database of approximately 1,300 wells. Eight drilling permits were issued in 1995-96 for wells in south Florida. One of these wells, Permit No.1289, drilled by Calumet Florida, Inc., at the Raccoon Point Field, became the state's first new producer since 1988. This well is currently producing 3,000 barrels per day, which is approximately 20% of the state's total crude oil production. Calumet drilled a dry hole at the Townsend Canal field and a horizontal well at the West Felda Field which is likely to become a producer. Calumet conducted one conventional seismic survey in 1995 and applied for 3-D seismic permit in the Raccoon Point area in 1996. Two additional horizontal well applications were submitted by Calumet at the end of 1996. DeSoto Oil and Gas, Inc. received a permit for drilling in Santa Rosa County in April, 1996. This well has not yet been drilled. Coastal Petroleum Company's application for drilling in state waters off St. George Island has been in court since being denied by the Governor and Cabinet in 1993. At the end of 1996 the application was still pending a final court decision. Coastal submitted two offshore geophysical applications during 1995-96, but has not yet received a permit. In federal waters south of Pensacola, Chevron completed a 40 million cubic ft/day gas well in the Norphlet Sandstone in April 1996. The company announced plans to construct production facilities and a pipeline which will deliver the gas to existing refineries in Mobile. By the end of 1996 Chevron, Amoco, and OEDC Exploration and Production had applied to the federal Minerals Management Service for numerous drilling and production permits. Modification of the West Felda Field Rules was approved on July 18, 1996. This modification allowed for additional wells which will drain the reservoir more efficiently. On March 24, 1996, the Oil & Gas Section adopted new rules which reflect the Governor's recent directive to streamline all rules. ADDITIONAL PROGRAMS A number of additional programs are critical to the mission of the FGS. These programs benefit Survey staff as well as other state and federal governmental agencies, industrial representatives, consulting groups, academic researchers, and interested citizens. The Survey's drilling program acquires cores from various locations around the state for in- house projects as well as for cooperative projects. The Geologic Sample Repository contains storage space for core and cutting samples, allowing this valuable information to be preserved and catalogued in a systematic fashion. Lithologic and geophysical logs are filed for ease of retrieval at the Gunter Building in Tallahassee. The Survey's computer system is used to handle the growing volume of information associated with geological research and oil and gas regulation. Currently, most FGS drafting services are handled by computer. The FGS's research library allows its users the advantage of computerized database searches along with traditional library services geared specifically to geology. The FGS supervises an active student assistant program in which qualified graduate and undergraduate students assist staff members in various on-going research programs. Continuing education at the Survey, while offering staff some advanced educational opportunities, has suffered from budget cutbacks. DRILLING PROGRAM The FGS maintains an active scientific drilling program. The state is characterized by very low topographic relief and data obtained from cores is essential to the understanding of subsurface stratigraphy, hydrogeology and hydrology. The FGS operates a Failing 1500 drill rig which is deployed on a full-time basis and is operated by a licensed driller and one assistant. During 1995 and 1996, 30 stratigraphic test holes were drilled by the FGS core rig, 15 of which were continuous cores ranging from 54 to 628 feet in depth, for a RESEARCH LIBRARY rW FGS drill rig (photo by Tom Scott) total drilled length of 3,828 feet (2,826 feet cored). Fifteen of these holes were converted to monitor wells in cooperation with the Suwannee River and South Florida Water Management Districts and the U.S. Geological Survey. The FGS operates a truck mounted Mobile Drill auger/core rig which has been outfitted for continuous shallow wireline coring in rock or unconsolidated sediments. Sixty-seven stratigraphic test holes, 59 of which were cored, were drilled in 13 counties during 1995 and 1996. Depths of auger/core holes range from 19 to 95 feet for a total sampled depth of approximately 3,375 feet. Thirty-five of these holes were converted to monitor wells in cooperation with the Florida Department of Environmental Protection Ambient Ground Water Quality Program and the Alachua County Department of Environmental Protection, the U.S. Geological Survey and the Northwest, Suwannee River, Southwest and South Florida Water Management Districts. The research library is an integral part of the Survey's research and regulatory programs. In support of the information needs of staff, students, and researchers from the public sector, the library provides access to basic research materials including books, maps, state and federal documents, photographs and periodicals. Holdings total approximately 40,000 volumes. Materials are collected on various aspects of geology, including mining and mineral resources, environmental geology, hydrogeology and other related topics. The library has one of the largest and oldest geologic map collections in the state of Florida with over 16,000 maps, including a number of items dating from the 19th century. LIBRARY SERVICES The library is used by the general public, students, other government agencies, and private consulting companies. While circulation is restricted to Survey staff, the personnel of other state agencies and the Florida State University Geology Department, the library is open to the general public for research. In addition, library materials are available to libraries throughout the United States via the Interlibrary Loan system on a limited basis. The library participates in a nationwide Interlibrary Loan network through which the staff has access to other special and academic collections. The library cooperates with other libraries through various networking groups on the local, state, and national level. The librarian participates in the activities of the Panhandle Library Access Network, and the Geoscience Information Society. In 1996, a committee was formed to study library services within the Survey's parent agency, the Florida Department of Environmental Protection. This committee is working to standardize library services within the Department, and to provide the remote offices better access to needed research materials. The Research Library currently subscribes to the GEOREF database on CD-ROM. GEOREF, the digital version of the American Geological Institute's geoscience database, contains almost two million records covering geology from 1785 to the present. In addition, the library now has full Internet access through the DEP network and is able to access the online catalogs of the State University System of Florida (LUIS), the State Library of Florida (LION), and many other sources of information available online. These enhancements in computer services allow library staff to expand the access of researchers to relevant material. PUBLICATIONS DISTRIBUTION The library is responsible for providing detailed information on the survey's 636 published documents and reports, and oversees the distribution of all documents currently in print. During 1995-1996 this included over 2,293 requests for 22,965 documents. In addition, publications are distributed to 250 depository libraries around the world, which maintain collections of Florida Geological Survey publications. Many of the FGS publications are used as study materials by geologists studying for the Florida Professional Geologist Licensing Exam which is given twice a year. The library is active in providing these publications and other information to those studying for the exam. SPECIAL PROJECTS The library worked in a cooperative project with the Panhandle Library Access Network to begin retrospective conversion reconn) of library cataloging records to machine readable format. This is the first step in the automation of the library which will lead to an online public access catalog, and computerizing the technical activities of the library (e.g., cataloging, circulation, serials management). The recon project is being funded by PLAN, with the technical work being done by AutoGraphics, Inc. SPECIAL COLLECTIONS The FGS Library houses the archives of the Florida Sinkhole Research Institute. This archive contains original records of field research of sinkhole occurrences, county maps of sinkhole locations, and copies of publications of the Florida Sinkhole Research Institute. A listing of the field records computer database has been published as Florida Geological Survey, Open-File Report 58, and is available through the Publications Office. The Survey also houses the archives of the National Association for Cave Diving (NACD), Florida chapter. NACD members have provided the Survey with underwater cave survey maps, video tapes of several cave conduit systems, and NACD publications. This collection is used by cave divers and geologists to gain insight into the cave network locations as well as the size, shape and hydrogeology of subaqueous caves in Florida. GEOLOGIC SAMPLE COLLECTIONS The FGS maintains separate collections of well and surface outcrop samples. The well sample collection contains approximately 17,500 sets of samples from research wells as well as water and oil wells. Most wells are represented by sets of drill cuttings. Eight hundred and ten wells are represented by continuous core or core samples (a total of approximately 173,000 feet). New core sample sets added to the archives were drilled by the FGS, Water Management Districts and geologic consultants. The sample repository facility occupies about 9,500 square feet, with 17,655 square feet of shelf space. A collection of approximately 4,900 outcrop samples and mineral specimens is maintained by the FGS at its headquarters in the Gunter Building. These samples are cross indexed by formation, lithology, county and location. The collection is referred to as the "M-Series." The M-Series is particularly valuable given Florida's high rate of growth and development. Surface exposures of critical lithologies have become inaccessible with the continued proliferation of roadways, shopping centers, parking lots and high-rise housing. These sample archives and the data base they represent are utilized by geologists at the FGS, many other state, federal and local governmental agencies, universities (both in and out of the state) and geological consultants. The FGS vertebrate and macro- invertebrate collections are now located at and curated by the Florida Museum of Natural History, in Gainesville, at the University of Florida. Both collections will be searchable via the Internet. DATA FILES Samples from wells which are stored at the FGS Sample Repository are indexed by accession number, county, and section, township, and range location. Lithologic logs, drillers logs, and information sheets which correspond to these wells are filed by county and accession number in a series of loose-leaf binders. Information from these books is gradually being transferred to the Survey's computerized data base which currently contains data from approximately 4,000 wells. A file of geophysical logs contains information for approximately 4,800 wells. Many of these wells have corresponding lithologic samples available and are assigned FGS accession numbers. Geophysical logs represented include electric (normal, lateral, SP), natural gamma, caliper, fluid resistivity or conductivity, temperature, single point resistivity, acoustic velocity, fluid velocity, neutron (porosity), and gamma-gamma (density). In addition, complete suites of geophysical logs accompany most permitted oil and gas wells. COMPUTER SERVICES Computer systems at the FGS have been used primarily for word processing, database management, information resources and computer-aided design in support of various data collection and research programs. Installation of a local area network (LAN) at the FGS, however, has substantially improved data security, management, storage and accessibility. In 1995, the FGS LAN was connected to the DEP user group through the Tallahassee Municipal Area Network (TMAN). This connectivity facilitates department-wide e- mail, use of shared hardware peripherals (i.e., plotters and scanners), software and other DEP LANs. Moreover, it provides the FGS staff with access to the Internet and it makes FGS databases more accessible to the Department of Environmental Protection (DEP), as well as other state, local and federal agencies and the general public. In addition to the lithologic database, other FGS databases include: 1) an oil and gas geophysical permit application database, 2) an oil and gas well database, 3) Florida mineral producers list, 4) partial inventory of geologic samples (cores and cuttings from over 17,000 wells), 5) inventory of sinkholes from the Florida Sinkhole Research Institute, and 6) inventory of geologic outcrop descriptions in Florida. Digital maps include county base maps, geologic maps, a statewide geomorphic map, location maps for cores and oil and gas wells, and a map of active mines in Florida. The FGS library is able to access the online catalogs of the State University System of Florida (LUIS) and the State Library of Florida (LION) through the Internet and through direct dial-up. This allows library staff to expand the access of researchers to relevant material. The FGS is now part of Internet on-line resources with a gopher site and a World Wide Web (WEB) home page. These resources provide access to a variety of FGS data and other geologic information. Information about the FGS and its programs and more than 4,000 lithologic logs are available from the FGS gopher and WEB sites, both of which reside on the Department of Environmental Protection (DEP) server. The gopher can be reached by typing "gopher:\\gopher.dep.state.fl.us". From this menu, select "Department of Environmental Protection," then choose "DEP Florida Geological Survey." Files containing the FGS lithologic database are found here, including a decoding program and user manual. GeoSys, Inc. has provided the program, which is freeware and allows the user to view and print the lithologic data. An ASCII-file version of the entire FGS List of Publications is also located at this gopher site. In addition, this gopher site also provides access to geologic maps for each county. For WEB Browsers, the DEP home page is also an informative stop. This page (http://www.dep.state.fl.us), provides links to several DEP agencies, including the FGS. The FGS home page may be reached at http://www.dep.state.fl.us/geo. The site contains digital FGS data, such as lithologic well data, the Open File Map Series geologic maps, program information and educational resources. STUDENT ASSISTANTSHIP PROGRAM The FGS sponsors an active student assistantship program which is beneficial for students and staff geologists. Qualified graduate and undergraduate students in geology obtain work experience in a professional setting while staff geologists, in turn, are assisted by knowledgeable and motivated individuals. The assistantship program was begun in 1974 and has run successfully, with minor interruptions, since then. Currently, most students are employed by contract and grant-funded studies. These students conduct research tasks while under the supervision of professional geologists on the Survey staff. As the program has developed, the FGS and several Water Management Districts have provided funding for assistants. Additional funding sources include the U.S. Minerals Management Service, the Florida Department of Environmental Protection, and the U.S. Geological Survey. CONTINUING EDUCATION Opportunities for continuing education available to staff at the FGS remained few in 1995-1996 as a result of budgetary cutbacks. The State of Florida continues to maintain a unique program in which tuition is waived for state employees enrolling in job-related courses on a space-available basis. A number of Survey staff have taken advantage of this program, enrolling in various courses related to their work. Most of the staff members participated in DEP workshops on Ecosystem Management, with several members teaching geological portions of the classes. Several attended a special in-house course on Clastic Sedimentology. Others completed outside training in using geographic information systems. COOPERATIVE PROGRAMS The FGS participates in cooperative programs with federal agencies, other state agencies, county agencies, and water management districts. Such programs greatly benefit all participants and the taxpayers of Florida by providing efficient staff and equipment usage and obtaining maximum results from ever-dwindling budget dollars. FLORIDA DEPARTMENT OF ENVIRONMENTAL PROTECTION AMBIENT GROUND WATER MONITORING PROGRAM The Ambient Ground Water Monitoring Section contracted with the FGS to investigate shallow aquifer systems at 32 sites in 16 different counties throughout the state during 1995 and 1996. Core holes were drilled at each of the sites for lithostratigraphic analysis and for FGS database purposes. Lithologic logs were generated for each core, formation picks made and the data entered onto the FGS computer data base. Monitor wells were constructed at 29 of the sites for the ambient ground-water monitor network. This lithologic information and the ambient ground-water quality information will be useful for a variety of ecosystem management decisions. The Northwest, Southwest and South Florida Water Management Districts and Alachua County also cooperated on these projects. BUREAU OF WATER RESOURCE PROTECTION AQUIFER SYSTEM VULNERABILITY MAPPING The Bureau of Water Resource Protection entered into an agreement with the FGS to complete the digitizing, editing and formatting of county maps and data entry for aquifer- system vulnerability mapping in preparation for future work in publishing and inputting this information into the Department's Geographic Information System (GIS) map library. The aquifer-system vulnerability data and maps were developed using DRASTIC, a mapping system developed jointly by the U. S. Environmental Protection Agency and the National Water Well Association. DRASTIC is an acronym for seven hydrogeological parameters that are combined to estimate aquifer-system vulnerability to pollution. The seven parameters are: depth to recharge, net recharge, aquifer media, soil media, topography, impact of vadose zone, and hydraulic conductivity. A numerical score for each parameter is assigned to each map polygon. The score for each parameter within each polygon is then multiplied by a weighting factor. The seven parameters are overlain and the weighted scores are summed for each polygon to create a composite DRASTIC aquifer-system vulnerability map. Higher scores indicate higher relative pollution potential. These maps indicate overall relative aquifer-system vulnerability and are an invaluable tool in land-use planning and resource and ecosystem management. DIVISION OF WATER FACILITIES and FLORIDA STATE UNIVERSITY AQUIFER STORAGE AND RECOVERY (ASR) GEOCHEMICAL STUDY In December, 1996, the Florida Geological Survey, the FDEP Division of Water Facilities and the Department of Geology at Florida State University entered into a two-year cooperative agreement to study the effect of the aquifer matrix on surface waters stored underground and the effect on the aquifer matrix by the stored waters. This investigation will provide valuable knowledge regarding the proper development and monitoring of ASR facilities. Surface waters injected underground may have chemical and physical characteristics quite dissimilar to the native waters they displace. The rocks comprising the aquifer matrix have attained their present chemical and physical state partly as a result of interactions with the native ground waters. The introduction of waters with different characteristics may change the previous naturally occurring rock-water interactions. A major concern for stored waters is the entrainment of various naturally occurring radioactive nuclides. In Florida, Eocene through Miocene carbonate rocks often have zones displaying considerable radioactivity. This is most apparent in borehole geophysical logs that reveal multiple zones of high gamma-ray activity coincident with layers rich in clay, organic, phosphate or dolomite. Uranium-series elements are often associated with these zones. Surface waters injected into deeper aquifer systems have the capability of dissolving some of the aquifer rock, which can mobilize the uranium-series elements into the ground water. A recent Florida Geological Survey study (Open File Report 61) in Hillsborough County demonstrates that up to 32 percent of the uranium in Floridan aquifer system rocks can be leached when exposed to oxidizing conditions in the laboratory. This further underscores the need to investigate the effects of pumping oxygen-rich surface waters into the aquifer. Analysis of both rock and water samples is necessary to track the source and mobility of uranium. The ASR geochemical study will measure the native Floridan aquifer waters, the waters being injected, the waters withdrawn after storage, and appropriate rock samples of the aquifer matrix in the area. The nature of particulate matter in the injected water will also be considered. The analyses to be carried out will be uranium concentration and the radioactivity ratio of 234U/238U, strontium concentration, 8Sr/86Sr, field conductivity, temperature, and pH, and major ion analysis (Na, Mg, Ca, CI, SO4, and HCO3). The uranium concentration and uranium isotope alpha activity ratio analyses will be done by alpha spectrometry. The strontium concentration will be done by atomic absorption, and the strontium isotope analyses will be done using mass spectrometric means. Laboratory facilities at the Florida State University (FSU) Department of Geology will be used during the investigation. COASTAL RESEARCH GROUP In 1991 an informal Coastal Research Group (CRG) was organized at the FGS. The Coastal Research Group is committed to continuing fundamental research to improve our understanding of Florida's coastal ecosystems and processes. This research will provide information that is essential for planning, ecosystem management, conservation, and protection of Florida's valuable coastal resources. From modest beginnings the CRG's responsibilities and projects expanded considerably during 1995 and 1996. At present, the research group's FGS staff consists of four licensed Professional Geologists who serve as principal investigators: Dr. Ron Hoenstine, Jim Balsillie, Henry Freedenberg, and Jim Ladner. The principal investigators have 86 years combined experience in Florida geology, coastal processes, and marine ecosystems. Other contributing FGS staff include geologists Jacqueline Lloyd, Ed Lane, Steve Spencer, and Ken Campbell. Engineering, maintenance, and navigation expertise is provided by Ted Kiper, an FGS staff engineer with a U.S. Coast Guard Captain's certification. In addition, the CRG staff collaborates with Dr. Joe Donoghue, a professor of coastal processes/marine geology in FSU's Geology Department. The Geology Department and the FSU Marine Laboratory provide access to field sampling equipment and research vessels, as well as analytical instrumentation for sedimentology and geochemistry. The collaboration between the CRG and FSU provides opportunities for directed graduate research studies funded through employment on the CRG research grants. Six graduate students from FSU's Geology Department are currently employed as research assistants on various CRG coastal projects. In the past, the CRG has cooperated similarly with University of Florida, University of South Florida, Florida Institute of Technology, and the Florida Institute of Oceanography. Boats in the CRG inventory include a 13.5-foot Boston Whaler, and a 24-foot jet- drive Carolina Skiff with a power winch for shallow water sediment sampling. For deeper water and heavy-duty sediment sampling the CRG uses the FGS RV Coastal Probe, a 30- foot, diesel powered, shallow draft, research vessel. This boat has a 2-ton-capacity hydraulic winch, a hydraulic clam-shell grab sampler, significant storage space, and a completely enclosed pilot house. FGS/CRG field equipment includes the following portable instruments acquired during this biennium: 1. A global positioning system (GPS) with real- time differential (Starlink MRB-2A radiobeacon receiver) for site location, station keeping, and station recovery. 2. A Hydrolab Remote Water Quality Logger for on-site measurement of salinity, temperature, depth, pH, conductivity, and turbidity. 3. A Go-Devil outboard motor designed to traverse shallow marsh and estuarine systems. 4. An electric portable vibracore system. 5. A receiver for FGS's Geopulse seismic profiler. 6. A recorder for FGS's Geopulse seismic profiler. 7. A video camera to provide a visual record of on-site data. 8. A 35hp jet drive outboard for the 13.5 foot Boston Whaler. 9. A computer graphics plotter (for digital graphics input, as well as publication and presentation output) . COASTAL RESEARCH GROUP PROJECTS The CRG's first research project, A Geological Assessment of the Florida Big Bend Coastal Wetlands, was initiated in July 1991 and continued through 1996. This project is partially funded by the U.S. Geological Survey. It focuses on characterizing the wetlands processes of the estuaries of the Aucilla, the Steinhatchee, the St. Marks, and the' Ochlockonee Rivers. The final comparison among these four Big Bend estuaries will enable better prediction of such natural systems' responses to changes that are either natural (e.g., sea level change) or human- induced (e.g., increasing development). The CRG also completed an environmental project partially funded by the U.S. Minerals Management Service (MMS): Baseline Investigation of Estuarine Sediment Metals for the Steinhatchee River Area of the Florida Big Bend. This was a baseline program to identify concentrations of metals within sediment facies of the Steinhatchee River estuary. Sediment metals-enrichment were related to basin land use where possible. A second MMS-supported study is MMS- 2, A Geological Investigation of the Offshore Area Along Florida's Central East Coast. This multi-year study is designed to characterize the geologic processes and parameters affecting the shore and nearshore coastal areas of Florida's central eastern Atlantic coast, as well as evaluate known and potential offshore sand resources for beach renourishment. Similar nearshore investigations by the FGS (1985- 1992) have examined the sand and heavy mineral resources off the Gulf Coast of northwest Florida, off Cape Canaveral on the Atlantic coast, north of Cape Canaveral to the Florida-Georgia state line, and off southeast Florida from Ft. Pierce to Miami. In 1996, the CRG completed an EPA sponsored project to conduct an inventory of Florida Gulf of Mexico investigations of offshore sand resources. The purpose of this inventory was to establish a database for future identification of offshore sands suitable for beach renourishment. NORTHWEST FLORIDA WATER MANAGEMENT DISTRICT During the years 1995-1996, the FGS provided technical assistance to several hydrogeological studies carried out by the NWFWMD. Under short-term contracts, FGS research assistants described the lithology of wells drilled for the Corry Field assessment, the Jackson County Karst Hydrogeologic Unit Assessment, and local studies in Bay and Washington Counties. Printed lithologic logs and digitized columnar sections were provided to the District, and samples from the studies were archived in the FGS sample repository. SUWANNEE RIVER WATER MANAGEMENT DISTRICT GEOLOGY AND HYDROGEOLOGY OF THE UPPER CARBONATE UNIT OF THE INTERMEDIATE AQUIFER SYSTEM IN BRADFORD AND UNION COUNTIES, FLORIDA The FGS and the Suwannee River Water Management District cooperated in this study in Bradford and Union Counties. The FGS drilled 19 sites, collecting continuous core or cuttings samples for lithologic and stratigraphic analysis, collecting split spoon samples for hydraulic conductivity analysis and constructing monitor wells at selected sites. One site includes an eight-inch well for aquifer testing. Each test hole will penetrate into the upper carbonate unit of the intermediate aquifer system. This unit is the primary source of potable water in the study area. Eight of the sites were located around the perimeter of Lake Samson to determine the relationship of the lake to the aquifer. WELL DESCRIPTION PROGRAM The FGS and the Suwannee River Water Management District (SRWMD) have maintained a successful and mutually beneficial working relationship for nearly 20 years. During much of this period, the SRWMD funded geology graduate students to work as research assistants at the FGS, describing well samples and cores and entering the coded lithologic logs into the FGS database. This arrangement has worked exceedingly well, resulting in the addition of much new data on the geology of the District to the databases of both agencies. This cooperative project continued through the years 1995-1996. During this period, over 100 previously unworked wells were described and added to the FGS database. In addition, data from the existing well file database was compiled to construct preliminary isopach maps of the surficial aquifer system within the SRWMD. A new contract to continue the well description and surficial aquifer delineation projects was signed in early October of 1996. In addition to a variety of other tasks, FGS research assistant Tom Miller describes the lithology of well cuttings. (photo by F. Rupert) SOUTH FLORIDA WATER MANAGEMENT DISTRICT and UNIVERSITY OF MIAMI SOUTHERN FLORIDA CORE DRILLING PROJECT The FGS, South Florida Water Management District (SFWMD), and the University of Miami are cooperating on this project. Three deep cores had been drilled by the end of 1994, two of which were converted to monitor/observation wells for the SFWMD. The remaining well in this project is located within the Everglades National Park and has a total depth of 648 feet. A shallow monitor well was constructed at this site. A fifth is currently being drilled near Sunniland, Collier County. Interpretation of these cores will significantly increase the information available on the subsurface framework of the Florida Keys and the formation of the Keys. This project is also being expanded to study the Pliocene coarse sands under southern Florida and their potential effect as a nutrient conduit to Florida Bay. ST. JOHNS RIVER WATER MANAGEMENT DISTRICT DISTRICT OBSERVATION WELL NETWORK (DOWN) A cooperative program was developed between St. Johns River Water Management District (SJRWMD) and the Florida Geological Survey in keeping with the missions of both agencies. SJRWMD is developing a District Observation Well Network (DOWN) program. Geologic samples obtained during the emplacement of these wells provide site- specific data which is vital in ascertaining local and, eventually, regional hydrogeologic conditions. Samples from the DOWN Program as well as other previously undescribed samples on file at the FGS will be inventoried, examined, described and entered into an electronic database for use by both the FGS and SJRWMD. SOUTHWEST FLORIDA WATER MANAGEMENT DISTRICT GEOLOGIC CROSS SECTIONS An on-going cooperative program was established in 1991 between the Southwest Florida Water Management District (SWFWMD) and the FGS to construct geologic cross sections throughout the 16-county SWFWMD region. The purpose of the project is to delineate the extent of lithostratigraphic and hydrostratigraphic units within the Southwest Florida Water Management District (SWFWMD), thus providing knowledge essential for the protection and management of ground-water resources in southwest Florida. The project is subdivided into three phases: Phase I includes the southwest region from Pinellas and Hillsborough to Charlotte Counties. Phase II includes the northwest region from Levy and Marion to Pasco Counties. Phase III includes the southeastern region, including Polk, Highlands, Hardee and DeSoto Counties. Detailed lithology, regional lithostratigraphy of Eocene through Miocene formations, gamma-ray log characteristics of these formations and aquifer-system delineations within each study area are the primary focus of the cross sections. Most of the data used to construct the cross sections are taken from detailed descriptions of wells drilled as part of the SWFWMD Regional Observation and Monitoring Program (ROMP). In areas where ROMP data are not available, borehole data from the FGS and U.S. Geo- logical Survey are utilized. Interim reports on each project phase are either in preparation or have been published. Twenty-one cross sections have been completed to date. A final report on the geologic framework of southwest Florida is planned and will be facilitated by further cooperative programs with the SWFWMD. GEOGRAPHIC INFORMATION SYSTEM DATABASE Through a cooperative agreement between the FGS and the Southwest Florida Water Management District (SWFWMD), more than 4,800 borehole records have been entered into a computer database and subsequently imported into Arclnfo. Each of these records contains up to 88 parameters, identifying well location information (including location accuracy), type and availability of geological data and samples, well construction information, well use, and other pertinent information. As a result of this effort, information on all wells in FGS files for which geologic samples or geophysical logs exist is easily accessed. This new GIS coverage provides an invaluable resource to many aspects of hydrogeologic and geologic research, ground-water management and protection and data evaluation/dissemination. U.S. GEOLOGICAL SURVEY FLORIDA BAY ECOSYSTEM HISTORY FGS staff member Dr. Tom Scott is assisting the USGS in the investigation of the ecosystem history of Florida Bay, part of the South Florida Ecosystem Restoration Project. This project is utilizing fossil mollusks, dinocysts, forams, pollens and sediment lithology to determine the environments present within the bay at a given time and location. Lead isotope dating techniques provide reliable ages of the sediments encountered. The project will run five years. THE HYDROGEOLOGY OF THE SURFICIAL AQUIFER SYSTEM IN COLLIER COUNTY, FLORIDA This is a cooperative project with the USGS. FGS geologists are describing cores, determining formational breaks and analyzing permeabilities in order to characterize the surficial aquifer system. Seven cores, averaging 200 feet deep, were drilled and lithologic descriptions completed during 1996. THE OLIGOCENE TO PLIOCENE SUBSURFACE STRATIGRAPHY OF SOUTHERN FLORIDA An ongoing cooperative project with the USGS was initiated in 1994 to investigate the subsurface stratigraphy of southern Florida. To date this investigation has produced some interesting results utilizing a multidisciplinary approach to study the strata. The most notable result was the determination that the Arcadia Formation, Hawthorn Group, began deposition in the late Early Oligocene and continued, in some areas, through the Early Miocene. This investigation documented the existence of the thickest and best preserved record of Oligocene deposition in the Atlantic and Gulf coastal plains. SURFICIAL AND BEDROCK GEOLOGY OF THE U.S.G.S. 1:100,000 HOMESTEAD QUADRANGLE This cooperative project is funded jointly by the FGS and the USGS under the State Geologic Mapping Program (STATEMAP) established by the National Geologic Mapping Act. The driving force for mapping in this area is the recent priority given the south Florida area by both state and federal agencies. The study area includes parts of the Everglades, Florida Bay and the Florida Keys. Geological Investigations section geologists field mapping by helicopter, Florida Everglades (photo by Tom Scott). The mapping of the Homestead Quadrangle is a two-year effort which started late in 1994 with the eastern half of the quadrangle, concluding with the western part in 1996. Twenty coreholes were drilled for this project. Numerous shallow push cores of surficial sediments and hand samples were collected. Surficial sediment maps, bedrock geology maps and cross sections of the shallow subsurface were produced. In August of 1996, the FGS began working on the 1996-1997 STATEMAP project. This FGS/USGS funded project will produce a bedrock geologic map, a surficial sediments map, and several geologic cross sections for the western two-thirds of the 1:100,000 scale Sarasota Quadrangle. Field mapping for this project began in November, with a planned completion date of August, 1997. NATIONAL WATER QUALITY ASSESSMENT (NAQUA) SUMMARY OF THE GEOLOGY AND HYDROGEOLOGY OF THE LITTLE RIVER BASIN, SUWANNEE COUNTY, FLORIDA This cooperative study by the FGS and the USGS National Water Quality Assessment (NAQUA) program investigated the geology and hydrogeology of the Little River basin, a karst drainage basin. The FGS drilled fifteen test holes into the Ocala Limestone (upper Floridan aquifer system) and collected core or well cutting samples for lithologic and stratigraphic analysis. Split spoon samples were collected from selected zones for hydraulic conductivity analysis. A monitor well was installed in each test hole for water quality sampling and to facilitate investigation of the interaction of surface and ground water. SPECIAL PROJECTS FLORIDA GEOLOGY EDUCATION VIDEO PROJECT In 1995, the FGS received funding from the Florida Advisory Council on Environmental Education to produce a classroom video on Florida geology. The Florida Geology Educational Video (FGEV) project, developed in conjunction with Diane Wilkins Productions and staff of the Florida Geological Survey, fulfills the need for Florida-specific geological education materials for use in the classroom and for general public information. The video, entitled Florida's Geology Unearthed, utilizes an enthusiastic and contemporary videographic approach to capture the target 8th- and 9th- grade student audience. The classroom version of the video includes a 58-page Educator's Guide and supplemental written materials all contained in an attractive notebook. A second version of the video (57.5 minutes) is intended for general public education through broadcasting via Florida Public Television or its affiliates.

PHYSICAL PLANT AND SCIENTIFIC LABORATORY UPGRADES During the biennium 1995-1996, a number of improvements to the FGS laboratories and the overall physical plant were carried out. These include both space renovation and equipment upgrades. FGS Storage Facility: An existing foundation "footprint" previously housing an old air conditioning/heating facility has been converted to an 18-foot by 12-foot "on-site" out-building for additional storage along the west side of the Gunter Building. This, in turn, has allowed for more efficient use of space and has allowed for FGS laboratory upgrades. Core Preparation Bay: One of two garage bays in the basement of the Gunter Building has been converted to a core preparation/description, rock cutting, and sedimentological preparation facility. Ro-Tap Box: A 3'(w) x 6'(1) x 5'(h) box, housing 2 rotating/tapping sedimentologic analytical devices (one of which staff has re- built) has been installed in the core preparation bay. The insulated box has been successful in eliminating potentially harmful decibel levels that the machines produce. Core Cutter: A safety-conscious core- cutting device and station has been designed, installed, and is in use in the core preparation bay. The lay-out table station and saw (the latter known as the Blade Runner) allows for splitting of PVC and aluminum core barrels up to 5" in diameter. Drill Press Corer: A drill press mounted, water-cooled coring device has also been constructed in the core preparation bay. The device allows for obtaining small, cylindrical cores of rock/core samples for detailed mass density, permeability, transmissibility, and related analyses. Top Loading Balance: A new state-of- the-art balance has been acquired for the sedimentological laboratory. This sensitive scientific device will measure mass (weight) of up to 810 grams (28.4 ounces or 1.77 Ibs). It rounds off to an astounding 0.001 grams. In addition, a "stilling box" has been constructed to eliminate effects of local drafts. It will accommodate introduced physical dimensions of objects to be weighed of 17"(w)x17"(1)x14"(h). The balance is fully configured to communicate with the proper computer interface. Permeameter Laboratory: The Falling- Head Permeameter (FHP) laboratory has been rebuilt and upgraded from 20 to 44 units. FHP analyses are time-consuming, requiring a one-month analytical period for completion. These analyses are commonly part of studies undertaken in the FGS' various cooperative contracts and grants. The FGS FHP lab has become the most comprehensive such laboratory in the State. A 3-tier analytical schedule has been adopted to determine transmissivity of samples, which has enhanced the efficiency of the laboratory. In addition, computer related automation for data recording and analysis is under consideration for the future. , FGS permeameter laboratory PUBLICATIONS Despite severe budget cutbacks, production of printed reports in the FGS publication series continued in the years 1995- 1996.

Cation Exchange Capacity And Normalization Of Trace Metal Concentrations In Sediments Of The Steinhatchee River Estuary, North- Central Florida, by C. A. Trimble, P. C. Ragland, J. F. Donoghue, R. W. Hoenstine, and A. B. Highley, 1995, Southeastern Section, Geological Society of America, Abstracts with Programs, v. 27, n. 2, p. 93. The Steinhatchee River Estuary is a small relatively pristine bay located on the northwest Florida Gulf of Mexico coast. Sedimentary accretion rates within the system vary 1.4-4.1mm/yr based on Pb-210. Samples collected from 31 locations, representing four sedimentary lithofacies, were analyzed for major and trace element content (ICP-AES), texture, total organic matter, clay mineralogy, and cation exchange capacity. Cation exchange capacity was determined by calcium exchange and weighting of excess salts. Two ICP extraction methods were evaluated: partial, aqua regia digestion and total, hydrofluoric acid digestion. The chemical and physical factors affecting the ability of a sediment to concentrate trace metals introduce uncertainty in distinguishing anthropogenic from naturally-occurring concentrations of many metals. The standard practice of normalization of metal concentrations assumes a linear relationship between either geochemical or sedimentological characteristics and the metal. The following standard methods were evaluated: granulometric normalization of metal concentrations against total weight % fines; geochemical normalization against reference elements (Al, Fe, and C); and normalization to sediment organic matter content. A new geochemical method, normalization against cation exchange capacity, was compared with accepted procedures. The best correlations were found when trace metals were normalized with respect to Al. Aqua regia, partial leach was as reliable, for most metals, as total digestion. Normalized data indicated little evidence of significant contamination in this system. Exceptions included lead levels, which appeared to be significantly elevated in a few areas of the salt marsh. Mercury values were also elevated with respect to the expected trends in three locations. Potassium and phosphorous also appeared slightly elevated in several of the marsh samples. This may be due to the presence of nutrient loading from local communities, or application of these elements in fertilizer. Facies, Fossils and Time A Discussion of the Litho- and Biostratigraphic Problems in the Plio-Pleistocene Sediments of Southern Florida, by T. M. Scott, and G. L. Wingard, 1995, in: T. M. Scott, compiler, Stratigraphy and Paleontology of the Plio-Pleistocene Shell Beds, Southwestern Florida: Southeastern Geological Society Guidebook 35, unpaginated. Florida's Plio-Pleistocene sediments contain one of the world's most spectacular and diverse fossil mollusk assemblages. The beds exposed in the APAC and Quality Aggregates pits are reported to contain over 1,000 species of fossil mollusks. The quality and quantity of preservation in these deposits has attracted the attention of professional and amateur paleontologists alike for over a century. Paleontologists have amassed vast fossil collections from an extremely limited number of exposures primarily located in southwestern Florida. Despite this extreme focus, however, there is only limited basic understanding of the age, stratigraphic position and depositional history of these beds. Numerous factors have played a role in preventing a valid litho- and biostratigraphic framework from being developed. Principal among these is the paucity of vertical sections where sedimentologic and biologic sequences can be studied. The few vertical sections that do exist are temporary exposures found in quarries, canals and construction sites; the short-lived nature of such localities makes them less than ideal for establishing type sections. Many type sections established by earlier workers for the named Plio-Pleistocene units are no longer available for study. The paucity of accessible exposures has led many paleontologists to collect fossils from spoil piles, not in situ. Stratigraphic analysis has been further encumbered by the interfingering and overlapping nature of diverse depositional facies. The discontinuous nature of many of the identified shell beds makes it difficult to trace units laterally or vertically. In addition, most of the depositional units are very thin; the entire Quaternary section is less than 30 feet thick in southwestern Florida. In many surficial exposures, once fossiliferous sediments contain only molds and casts of fossils or the fossils have been destroyed altogether. This effectively limits the biologic information available for interpretation. Often sedimentologic changes, including the recognition of disconformities, between faunally-derived units are insufficient to separate the sediment packages into formational units. These factors have resulted in the application of lithostratigraphic names to units defined on the basis of the fossils, essentially a biostratigraphic unit. Geology and Geomorphology of Okaloosa County, Florida, by W. Schmidt, 1995, in; U.S.D.A., Natural Resource Conservation Service, Soil Survey of Okaloosa County, Florida, p. 3-6. Late Paleogene and Neogene Sea Level History of the Southern Florida Platform and Phosphatic Sediment Deposition, [abs] by T. M. Missimer and T. M. Scott, 1995, Society for -Sedimentary Geology (SEPM) Annual Meeting, St. Petersburg, Florida, August 1995. Eleven third-order sea level events were recognized from sequences within the stratigraphic record beneath the central part of the Southern Florida Platform between 3.4 and 35 Ma based on seismic reflection data, sequence stratigraphic analysis of cores, and detailed chronostratigraphic analysis. The major sequences found within the stratigraphic section are separated by a number of major hiatuses. The most significant hiatuses correspond to the following global sea level events: mid- Pliocene (0.1 to 0.2 million years missing), Late Miocene (2.5 to 3 million years missing), Middle Miocene (2.5 to 3 million years missing), Oligocene-Miocene boundary (2 to 2.5 million years missing), and mid-Oligocene (2 million years missing). The sea level curve for the Southern Florida Platform corresponds closely to the global sea level curve with the exception of the Early Miocene between about 20 and 23 Ma. Three significant sea level events occurred in that time frame with outer ramp to restricted subfacies stacking patterns indicative of major changes in eustatic sea levels. There are no corresponding closely time-spaced events shown on the Haq curve for this time period. Based on the relative sea level data for the Southern Florida Platform and composition of the sediments, phosphogenesis began in the Late Oligocene at about 28 Ma. The episode of maximum phosphate deposition occurred between 20 and 23 Ma, which does not correspond to the period of maximum flooding, dated between about 14 and 17 Ma. Metal Analyses In Sediments Of The Steinhatchee River Estuary, North-Central Florida, by C. A. Trimble, P. C. Ragland, J. Donoghue, A. B. Highley, and R. W. Hoenstine, March, 1995, Southeastern Section, Geological Society of America, Abstracts with Programs, v. 27, n. 2, p. 93. The Steinhatchee River Estuary is a small, relatively pristine bay located on the Florida Big Bend coast. The Steinhatchee River is part of a unique, sediment-starved and karst-controlled watershed. The river flows across north Florida for approximately 55 kilometers through woodlands, wetlands and tree farms prior to entering the Gulf of Mexico. Sedimentation rates in the bay, determined by lead-210, are quite low, ranging from about 1.4mm/yr in intertidal marshes to about 4.1mm/yr in subtidal areas. Sediment organic matter content ranges from less than 1% in the open estuary to greater than 50% in the organic-rich salt marsh sediments. A set of 66 short cores was collected from four different sedimentary environments. These samples were analyzed for major and trace metal content, texture, mineralogy and total organic matter. Presently used methods of metal data analysis and normalization were examined for the purpose of determining which normalization technique is most robust and universally applicable. Metal data were normalized against several reference elements, including aluminum and carbon. Normalization against total fines, clay content and total organic matter was also examined. Two sediment digestion techniques were compared: aqua regia leaching and HF digestion. Preliminary data indicate that both digestion methods provide similar normalization results. Open-System Behavior in Karst-Related Wetlands in Florida, by P. A. Bond and J. K. Osmond, 1995, Geological Society of America, Abstracts with Programs, v. 27, n. 6, p. A-307. Ongoing hydrogeologic processes associated with wetlands in Florida have been examined using uranium series isotopes. The wetlands studied here are located in isolated karst-related depressions in central peninsular Florida. In both study areas ground water is mainly associated with the Floridan aquifer system and is under artesian conditions. Radiocarbon dates from other studies indicate that peats from the eastern site (Brevard Co.) were deposited between approximately 11,000 and 5,000 years before present. Organic matter from the western site (Polk Co.) could not be dated using the radiocarbon method. Vertical sequences of samples have been analyzed for uranium and thorium. Uranium in Florida is mainly associated with the phosphate-bearing mineral carbonate fluorapatite, and is transported via oxidizing ground waters. The concentration of uranium in organic matter and disequilibrium within the uranium-series isotopes suggests that these deposits are subject to open-system behavior. This work suggests that these wetland deposits interact with the local ground-water regime and modify it by removal of dissolved metals. Preliminary results indicate that uranium may exhibit some vertical movement within the deposit. Although the wetland deposits considered here are by no means modern, they continue to be active geochemical elements in their current hydrogeological setting. Phosphate Deposition in the Oligocene: Implications for Southern Florida [abs], by T. Scott, G. L. Wingard, L. E. Edwards, and S. D. Weedman, 1995, Society for Sedimentary Geology (SEPM) Annual Meeting, St. Petersburg, Florida, August 1995. The base of the Arcadia Formation, Hawthorn Group, marks the deepest occurrence of phosphate in southern Florida. Recent age determinations using 87Sr/8Sr of unaltered skeletal grains, dinocysts and mollusks indicate that Hawthorn deposition began at different times in different parts of the Florida Platform. Although the base of the Hawthorn has been traditionally placed at or near the base of the Miocene, our studies show that the age is latest early or earliest late Oligocene in southwestern Florida in the South Venice core in Sarasota County and earliest early Oligocene in eastern Florida in the Phred #1 core in Indian River County. Pelletal phosphate grains occur throughout the Hawthorn Group in concentrations ranging from a trace to more than 30 percent. Most phosphate grains occur with detrital quartz sand and appear to have been remobilized from the area in which they formed. Therefore age determinations on the sediments that host the phosphate grains indicate the age of their final deposition and can only suggest a minimum age for phosphogenesis of 31 million years. Diagenetic studies of the Arcadia Formation reveal significant leaching. In the upper 70 m, dolomite rhombs have hollow centers, skeletal grains are extensively leached and phosphate grains commonly are pitted to partially dissolved. Consequently, phosphate grains would be inappropriate for 8Sr/86Sr age determinations of phosphogenesis. Our studies reveal that the age of the base of the lithologically defined Hawthorn Group is nonsynchronous. Thus, on the Florida Platform, the shift from the carbonate- dominated sedimentation to phosphatic, siliciclastic-dominated sedimentation was more complex than previously envisioned. Preliminary Analysis of Integrated Stratigraphic Data from the Phred #7 Corehole, Indian River County, Florida, by S. D. Weedman, T. M. Scott, L. E. Edwards, G. L. Wingard and J. C. Libarkin, 1995, U.S. Geological Survey Open File Report 95-824, 63p. The lithostratigraphic sequence penetrated by the Phred #1 corehole in Indian River County, Florida, was analyzed utilizing an integrated stratigraphic approach. The core encountered sediments ranging from Upper Eocene to Holocene. The analyses included Sr isotopes, mollusks, dinocysts, mineralogy, and diagenesis. The data gathered is part of an ongoing project to better define the Cenozoic strata of southern Florida. Sedimentary Characteristics Of Central Florida East Coast Sands, by H. Freedenberg, Z. Chen, and R. W. Hoenstine, 1995, First SEPM Congress on Sedimentary Geology, Programs and Abstracts, v. 1, p. 56. Onshore sampling along the central east coast of Florida has locally revealed a distinct transgressive sedimentary sequence. The sampling program included the collection of 15 pushtube cores and two vibracores. More than 100 granulometric analyses have been performed on splits obtained from these cores and organic rich sediments have been prepared for radiocarbon dating. Results of the sampling program demonstrate several regional trends: 1) Carbonate content of the beach sands increases to the south. 2) In many areas, the beach sediment is comprised of two distinct populations, a fine grained, subangular to rounded siliciclastic fraction and a medium to gravel sized, rounded to subangular carbonate fraction. 3) The carbonate fraction consists exclusively of biogenic debris. 4) The siliciclastic sediments show evidence of transport while the biogenic sediments are locally formed. All fieldwork was accomplished by the Florida Geological Survey in a cooperative effort with the United States Minerals Management Service. This work was performed as part of a multi-year study designed to locate and characterize sands suitable for beach nourishment along the central east coast of Florida. Future phases of this study will integrate the onshore data with a new offshore sampling program. Siliciclastic Facies Belt Formation and the Late Oligocene to Middle Miocene Partial Drowning of the Southern Florida Platform, [abs.], by T. M. Missimer, and T. M. Scott, 1995, Geological Society of America Annual Meeting Program, p. 112. A series of siliciclastic shoreline deposits began to penetrate onto the Southern Florida Platform during the deposition of the Early Oligocene age Suwannee Limestone. These siliciclastic sediments were composed of fine to very fine quartz sands deposited in belts running parallel to the margin of the platform. The influx and mixing of these siliciclastic sediments did not affect the continued deposition of carbonate sediments on the platform because the sediments did not contain significant quantities of mud and the major siliciclastic sediment influx occurred during minor regressive, eustatic sea level events affecting primarily the platform margins. Beginning in Late Oligocene time, the frequency and volume of siliciclastic sediment influx onto the Southern Florida Platform began to cause the drowning of the eastern margin of the platform. The eastern margin of the platform receded from the current geographic margin position westward a distance of about 110 to 130 km. In the central part of the platform about 185 m of mixed carbonate and siliciclastic sediment was deposited from the Late Oligocene to the Middle Miocene (Chattian to Serravallian) compared to a maximum of about 20 m of mixed carbonate and siliciclastic sediment along the eastern margin of the platform. Subsequent influx of predominantly siliciclastic sediment with some carbonates terminated the growth of the platform and infilled the drowned part of the platform to produce the approximate geometry observed today. The influx of siliciclastic sediments occurred primarily in Late Miocene and Early Pliocene time, first as a series of southward prograding shoreline deposits with primarily mud deposition on the shelf to the east and later as a southward prograding deltaic sediment complex. Stratigraphy and Paleontology of the Plio- Pleistocene Shell Beds, Southwestern Florida: Compiled by T. M. Scott, 1995, Southeastern Geological Society Guidebook 35, unpaginated. This field trip guidebook discusses the problems inherent in the current way that many geologists view the Plio-Pleistocene shell beds in southern Florida. Alternative methods of understanding these beds are discussed. Stratigraphic Variability In Confining Materials Overlying The Floridan Aquifer System in a Regional and Local (sublake) Geologic Framework: Lake Wales Ridge, Central Florida [abs], by J. D. Arthur, A. Tihansky, and R. DeWitt, 1995, First SEPM Congress on Sedimentary Geology, Abstracts and Programs, v. 1, p. 26. Seismic-reflection profiles from four lakes within the Lake Wales Ridge in Polk and Highlands Counties, Florida, provide local detail within the regional hydrogeologic framework as described by litho- and hydrostratigraphic cross sections. These cross sections provide proximal geologic control and identify relationships between geologic formations and aquifer-system units. Clays of the Peace River Formation (Hawthorn Group) comprise the bulk of the confining beds within the intermediate aquifer system/confining unit, which separates the surficial aquifer system from the Floridan aquifer system. These confining beds are less than 10 feet thick in the northern part of the study area and thicken southward, where they become interbedded with more permeable carbonates of the Peace River and underlying Arcadia Formations. In general, reflectors observed in the sublake seismic data are of two types: 1) a discontinuous, irregular surface, and 2) a more continuous, concordant package that may be flat-lying or undulatory, exhibiting sags and/or draping structures. The discontinuous reflectors appear to correlate with the uppermost occurrence of carbonate, whereas the sagging structures appear to correlate with clayey confining units of the Peace River Formation. Seismic profiles suggest a relation between bathymetry and reflector type. Generally, deeper parts of the lakes are underlain by the deeper, irregular reflectors; the draping and sagging reflectors are observed beneath shallower parts of the lakes. These relations between bathymetry and reflectors suggest that confining units have controlled syn- to post-depositional (Neogene and younger) karstification and local ground-water recharge. Localized breaches within the confining units may contribute to greater hydraulic connection between the surficial, intermediate and Floridan aquifer systems.

Between The Dean Formation (Great Smoky Group) and the Shields Formation (Walden Creek Group), Western Blue Ridge, Southern Appalachians, by S. L. Palmes, 1996, Southeastern Section, Geological Society of America, Abstracts with Programs, v. 28, n. 2., p. 40. The stratigraphic succession of the Ocoee Supergroup has traditionally been broken into the basal Snowbird Group (overlying Grenvillian basement), the Great Smoky Group and the Walden Creek Group. The Dean Formation (DF) is the uppermost unit of the Great Smoky Group and the Shields Formation (SF) overlies the Licklog and is overlain by the Wilhite and Sandsuck Formations of the Walden Creek Group. A stratigraphic correlation between the SF and the DF recently proposed by Carter and others offers an innovative but radical departure from the traditional stratigraphic succession. The significant differences in overall lithology and clast population between conglomerates of the DF and SF indicate that either these rocks cannot be correlated, or that the provenance differed significantly across the intervening Copperhill anticline. Other significant differences between these units include bedding thicknesses, grain sizes, types of primary structures, and position in stratigraphic succession. Additionally, a correlation between DF and SF requires the Wilhite and Sandsuck Formations to be correlative with the Nantahala and Brasstown Formations of the Murphy belt, further requiring the Licklog Formation to be correlative with equivalents of the Ammons, Boyd Gap, or Hothouse Formations. Until these issues can be satisfactorily resolved, the correlation between the DF and SF should be viewed as one of several significantly different working hypothesis relative to correlation of units in the Walden Creek Group. Paleontology and Lithostratigraphy: Applications to Hydrogeological and Environmental Problems in Southern Florida, by T. M. Scott and G. L. Brewster-Wingard, 1996 [abs.]: Southeastern Section, Geological Society of America Abstracts with Programs, v. 28, n. 2, p. 43. A number of environmental issues are currently of great concern in southern Florida. Among these are the quantity, quality and distribution of water, waste disposal, and the occurrence of cover subsidence karst features. The surficial aquifer system provides water for many urban areas. Waste disposal occurs on top of and within the surficial aquifer system. The surficial aquifer system is developed in the Pliocene- Pleistocene siliciclastics, carbonates and shell beds that encompass the Tamiami Formation and the Caloosahatchee, Bermont and Fort Thompson faunal units. Difficulties in recognizing the position and age of the sediments that comprise the surficial aquifer system arise from the use of fossil mollusks to determine "formational" units. It has been proposed that the Caloosahatchee, Bermont and Fort Thompson faunal units (often referred to as formations) be placed in the informal Okeechobee lithologic unit. The determination of biostratigraphic zones and depositional environments, using paleontologic data, provides information on the distribution and interfingering relationships of lithofacies. Paleontologic data coupled with lithostratigraphic data identifies the position within the aquifer system and aides in the identification of aquifer characteristics. In addition, these data can serve as a predictive tool in determining flow direction, water quality and water quantity. Depositional environment data can assist in determining the aquifer system pollution susceptibility and aid in locating waste management sites. Depositional environment data also aides in delineating areas where cover subsidence karst features caused by dissolution of shells may be a hazard. The use of paleontologic and lithologic data provides a valuable tool to aid in the protection and responsible use of resources in southern Florida. The Hawthorn Group: A Historical Perspective, by T. M. Scott and G. L. Wingard, 1996, [abs.], Florida Scientist, v. 59, p. 24. The phosphatic siliciclastics and carbonates of the Hawthorn Group have been investigated for more than a century. The Hawthorn is widespread in the State forming the intermediate confining unit/aquifer system. It is economically important due to the occurrence of phosphate and fuller's earth. Until the 1980's, the Hawthorn Group was considered to be Middle Miocene. In the 1980's, the age of the Hawthorn was recognized to range from latest Oligocene or earliest Miocene to earliest Pliocene. Current biostratigraphic investigations have extended the range from late Early Oligocene to Early Pliocene. Future research will continue to investigate the depositional patterns, facies relationships, and biostratigraphy of the Hawthorn Group. Uranium Series Disequilibrium in Florida Wetland Deposits [abs.], by P. A. Bond and J. K. Osmond, 1996, Geological Society of America Abstracts with Programs, v. 28, n. 7, p. A-409. The interaction of dissolved metals with organic deposits in the shallow geologic environment of Florida has been examined using U-series disequilibrium techniques. This interaction is environmentally significant since the organic deposits are related to wetlands. These areas are continually pressured by the relentless development which accompanies Florida's extraordinary population growth. Although the botanical and zoological aspects of wetlands have been extensively documented, their geochemical significance is poorly understood. The redox-related solubility behavior of U and Th, coupled with alpha-recoil induced fractionation between U-234 and parent U- 238, are especially useful tools in Florida's hydrogeological environment. Carbonate fluorapatite from the widespread Hawthorn Group acts as a source of uranium, which may then be leached and transported by oxidizing ground waters. Isotopic evidence suggests that organic deposits function as geochemical sinks while simultaneously exhibiting open system behavior. The distribution of uranium and thorium isotopes in vertical suites of samples from organic deposits in several hydrogeologic settings have been examined. Results of this work indicate that, locally, on an ongoing basis, and to a variable extent, organic deposits function as geochemical sinks in Florida. It is suggested that in sensitive hydrogeologic settings, the geochemical significance of an individual wetland should be considered along with botanical, zoological, and hydrological aspects when policy is decided. Testimony in Support of the Reauthorization of the National Geologic Mapping Act of 1992 (H.R. 3198), by W. Schmidt, 1996, Written testimony submitted on behalf of the Association of American State Geologists to the U.S. House of Representatives Subcommittee on Energy and Minerals Resources, 4/23/96. The Florida Geological Survey's Environmental Geology Programs, by J. M. Lloyd, 1996, Environmental Geology, vol. 27, p. 71-72. An understanding of Florida's environment has become a major focal point of public policy. There is an increased public awareness of the fragility and importance of the environment, its relationship to the state's economy, and its effect on the quality of life and health. Recognizing this, the Florida Geological Survey established the Office of Mineral Resources and Environmental Geology in 1985. The section's staff conducts applied geologic research in the areas of mineral resources and environmental geology. Environmental geology research includes two main program areas. Florida's phenomenal population growth places unusual stress on the environment; thus, one program area focuses on the hydrogeology and environmental geology of specific high-growth urban areas. In addition, Florida beaches and coasts are a major economic draw for the state's tourist industry; thus, the other program area focuses on coastal sedimentology and processes.

BUDGET SUMMARY During FY 1994/95, the FGS was funded primarily from General Revenue. Some positions concerned with minerals and related resource issues were funded by the Nonmandatory Land Reclamation Administration Trust Fund. One Engineer III position in the Oil and Gas Section was funded from the Petroleum Exploration and Production Bond Trust Fund. During FY 1995/96, the General Revenue funding and Petroleum Exploration and Production Bond Trust Fund was transferred to the Minerals Trust Fund; Nonmandatory Land Reclamation Administration Trust Fund remained the same. The requested budget is reviewed by the Division of Administrative and Technical Services and the Secretary's Office of the Department of Environmental Protection before being presented to the Governor. Upon approval, the budget request is submitted to the Florida House of Representatives and the Florida Senate for review by their budget committees. The appropriations listed below include all funding, including outside contracts.

M. Lloyd. Florida oil production began to decline in 1979 and generally has continued to do so; however, production increased by eight percent from 1993 to 1994. Production then declined by six percent during 1995. Two of the south Florida oil fields (Sunoco Felda, and Sunniland) are nearing the end of their production history. The last reported production from Sunniland field was in 1991 and the last reported production from Sunoco Felda was in 1992. Exploration activity during 1994 and 1995 was very limited. There were no exploratory wells drilled, however, one well which was completed in 1993 is included in this report because the completion report was received in 1994. This Santa Rosa County well was plugged and abandoned as a dry hole. Geophysical exploration during 1994 and 1995 covered only 22.5 miles of seismic lines in the Florida panhandle, 20.3 miles of seismic lines in south Florida, and 102 miles of gravity survey in south Florida. In addition to this completed geophysical exploration, a permit application was pending for an extensive offshore seismic, gravity, and magnetic survey. A similar area was covered by an approved permit during 1992/93 but the permit expired without any exploration having been conducted. This exploration would potentially explore a dense grid off Florida's Gulf coast extending from offshore of Apalachicola, Franklin County to offshore of Naples, Collier County. One exploratory well was being drilled in federal waters off Florida at the close of 1995. This well will be the fourth drilled in the Destin Dome area by Chevron. Two of the previously drilled wells were classified by the federal government as producible Norphlet gas discoveries. A summary of offshore exploratory drilling is included in this report, as well as descriptions of each of Florida's 22 oil fields. The descriptions include discovery data, geologic information, and production totals. Open File Report 61 Lithostratigraphic and Hydrostratigraphic Cross Sections Through Hillsborough and Pinellas Counties, Florida, 1995, by R. Green, J. Arthur, and D. DeWitt. In cooperation with the Southwest Florida Water Management District (SWFWMD), the Florida Geological Survey (FGS) utilized detailed well sample descriptions, gamma logs, and hydrologic data to construct a series of six geologic cross sections through the District. Topographic profiles are included on each section to facilitate comparison of surface morphologies with subsurface stratigraphy. Delineation of formational boundaries is based on inspection of available borehole samples (cores and/or cuttings) by geologists from the SWFWMD and FGS. Hatching patterns are used on the hydrostratigraphic columns to show the three aquifer systems present in the study area. Open File Report 62 Core Drilling and Analysis: City of Sarasota, Downtown Well Field, Revised, by K. M. Campbell, T. M. Scott and R. C. Green. The Florida Geological Survey (FGS), in cooperation with the U.S. Geological Survey (USGS) and the city of Sarasota, drilled and analyzed a deep core hole located at the Sarasota Downtown Well Field (SDWF). The investigation focused on the Neogene and Paleogene lithostratigraphy and the Floridan aquifer system. The corehole was drilled into the top of the Middle Eocene Avon Park Formation and terminated at a total depth of 1,101 feet below land surface (bls). A four- inch diameter monitor well was constructed after coring was completed with a monitor zone from 353 to 590 feet. The core obtained in this study is cataloged as well W-16999 and is stored in the FGS core repository. A lithologic description for the core was generated utilizing a binocular microscope. The description was recorded in the standard FGS format and entered into the FGS data base. A stratigraphic column was also generated from the lithologic log. The SDWF draws water from both the intermediate and Floridan aquifer systems. The intermediate aquifer system and confining units consist of Neogene and Paleogene Hawthorn Group sediments. The Floridan aquifer system is composed of latest Paleogene sediments of the Hawthorn Group, and Paleogene sediments of the Suwannee and Ocala Limestones and the Avon Park Formation. Open File Report 64 Microfossil Sample Preparation and Techniques, 1996, by Ron Hoenstine. Sample preparation procedures for a diversity of microscopic fossils including calcareous nannoplankton (coccoliths), diatoms, foraminifera, and ostracods are presented in this report. This includes techniques for concentrating specific microfossil groups for investigation. Open File Report 67 Topographic Maps, Useful Tools for the Florida Fossil Hunter, 1995, by Frank R. Rupert. One of the more useful maps for the avocational and professional paleontologist alike is the topographic map. Topographic maps show the locations and form of hills, valleys, streams, and other natural features as well as many manmade landmarks. The entire state of Florida has been mapped by the U.S. Geological Survey in 7.5 minute topographic quadrangles. One thousand and thirty-seven 7.5 minute maps are required to cover the state. A handy index showing the locations and names of all 1,037 quadrangle maps covering the state is printed by the United States Geological Survey. Earlier topographic maps, generally dating from prior to 1940, were based on 15 minute quadrangles. These covered an area equivalent to four of the 7.5 minute maps, and had a scale of 1:62,500. The larger, modern 7.5 minute maps generally provide better detail, although the older maps can often be used to document historical changes in land features or urban sprawl. In many regions of Florida, topographic maps may prove extremely useful to the avocational paleontologist in search of fossiliferous exposures. They are an aid in locating mines, quarries, sinks, and incised streams, all features which might expose otherwise buried fossiliferous strata. This report includes several examples of how topographic maps may be used by fossil hunters in different parts of Florida. Open File Report 69 A Geological Investigation Of The Offshore Area Along Florida's Central East Coast, 1995, by H. Freedenberg, R. Hoenstine, Z. Chen, and H. Williams. This report documents a literature review, data search and findings of the Year 1 cooperative agreement between the United States Minerals Management Service (MMS) and the Florida Geological Survey (FGS). The purpose of this agreement is to identify and characterize offshore sands suitable for potential beach restoration along the central east coast of Florida. Southern Brevard, Indian River, St. Lucie and Martin Counties are included in this study. Year 1 tasks include contacting local organizations to provide a history of previous work done in the study area, conducting a thorough literature search to document past work done in the area of investigation, collecting representative onshore push cores and vibracores to characterize existing beach sediment, and determining existing zones of maximum erosion/accretion based on the literature search and local interviews. This report, which serves as a Year 1 annual report for this MMS cooperative agreement, consists of an introduction and summary, annotated bibliography and coastal atlas. Selected photographs of field activities are also included. A map indicating proposed seismic coverage for future phases of this study was prepared as part of the coastal atlas. Grain size distribution summaries are included in the lithologic log and granulometrics section. In the course of preparing this report, more than 160 reprints and professional publications were examined to document work previously done in the study area. Of these publications, 40 were considered Historical Background and Regional Summary papers, 42 documents concerned Sediment and Wave Mechanics, six papers were concerned with Breakwater and Groin Design, 71 papers were case history oriented Beach and Inlet Studies and nine papers discussed Field Procedures and Techniques. Fifteen PVC push cores and two aluminum vibracores were also collected as a part of this investigation. Fourteen of these cores were collected at arbitrarily chosen locations throughout the study area. The fifteenth core was collected at a control location on Cape Canaveral in northern Brevard County. Two hundred and nineteen samples were extracted from these cores for granulometric analysis. A subgroup of forty- nine granulometric samples was chosen for digestion in hydrochloric acid. These samples were also analyzed to determine size distribution of the carbonate grains. Median grain size for the entire sample population was found to be 0.433mm (1.2f). Median size of the carbonate grains was determined to be 0.602mm (0.73f) and median silica grain size was 0.366mm (1.45f). The carbonate grains were locally formed and primarily biogenic in origin (shell fragments and coral debris) while the silica grains showed evidence of longshore transport. Overall sample grain size and silica grain size distributions were found to approximate log- normality while the carbonate grain size distribution was, in many cases, bimodal. Bimodality of the carbonate grains can be attributed to distinctive populations of coarse shell fragments and finer grained abrasion products. Carbonate abundance in the digested sample was highly variable ranging between 18.80 and 83.52 %. In general, carbonate abundance in beach sand increases as one moves southward along Florida's east coast. An Appendix showing the results of grain size distribution analyses has been included in this report. A coastal atlas was prepared for the study area (Part III of this report). This atlas includes information on bathymetry, information on previous geophysical surveys, location of previously collected grab samples, push cores and vibracores. Areas of eroding shoreline are also shown along with information on known hardbottom areas (where available). Aerial photography was used in developing these data (photo inventories are maintained at the Bureau of Beaches and Coastal Systems of the Florida Department of Environmental Protection and at the Florida Department of Transportation). A preliminary coverage grid has been developed for future offshore acoustic profiling work. Findings of this investigation indicate that the largest concentrations of offshore sand suitable for beach nourishment are found on shoals paralleling the coastline. While past generic assessments of these resources have been made, detailed studies are needed in order to characterize these sands. In view of the ever-increasing need for renourishment sand, it is important that these resources be delineated as soon as practical. Open File Report 70 The Geomorphology and Geology of Taylor County, Florida, 1996, by Frank R. Rupert. Designed primarily as a general overview of the geology of Taylor County, Florida, this report provides information on the geomorphology, Middle Eocene to Recent stratigraphy, ground-water aquifer units, and mineral resource commodities in the county. The landforms and shallow stratigraphy are illustrated in a geomorphic map and two geologic cross sections. Special Publication 40 William F. Tanner on Environmental Clastic Granulometry, 1995, compiled by James H. Balsillie. This work presents, describes, and discusses sedimentologic field sampling, sample analysis, data reduction, numerical and statistical analytical methods, and interpretive tools for granulometric endeavors. Determination of agents of transportation and deposition form the focal issue of the work. Applications and methods contained in the publication represent over 45 years of applied research on the part of W. F. Tanner. FLORIDA GEOLOGY EDUCATION VIDEO PROJECT The solid earth is a fundamental and critical component of Florida's ecosystems: we need to know about earth materials because we live on them and depend on them. Geology affects our lives and economy. An understanding of Florida's solid earth, such as ecosystems, aquifers, geologic history and framework, energy and mineral resources, and geologic processes and hazards is essential toward effective, holistic environmental education. The Florida Geology Educational Video (FGEV) project, developed by Dr. Jon Arthur, Diane Wilkins Productions and staff of the Florida Geological Survey fulfills the need for Florida-specific geological education materials for use in the classroom and for general public information. The video, entitled Florida's Geology Unearthed, utilizes an enthusiastic and contemporary videographic approach to capture the target eighth- and ninth-grade student audience. The classroom version of the video includes a 58-page Educator's Guide (Lane and Rupert, 1996) and supplemental written materials all contained in an attractive notebook. A second version of the video (57.5 minutes) is intended for general public education through broadcasting via Florida Public Television or its affiliates. Seven hundred and fifty classroom versions of FGEV are being distributed to Florida's 72 school districts, as well as to local, community college and state libraries, state departments, museums, DOE Regional Service Projects and professional teaching organizations. Five broadcast copies will be marketed and distributed to selected public television stations within the state. Goals and objectives of the FGEV project include: 1) demonstrate why geology is important regarding infrastructure demands due to Florida's population growth; 2) describe Florida's unique geologic history, how it relates to geologic processes and hazards, and how it has shaped the land surface of present-day Florida; 3) establish the importance of geology to the understanding of Florida's ecosystems; 4) complement existing state-wide education curriculum standards as described in Science For All Students and the Sunshine State Standards (Florida Department of Education): the Educator's Guide will help implement the FGEV project into classroom curricula, where classroom discussion is fostered through video stops and suggested Learning Activities in the Guide; and 5) instill personal awareness of and responsibility for Florida's renewable and non- renewable solid-earth resources by clarifying the relationship between the depletion of these resources and Florida's economy. An advisory committee of local environmental educators, including eighth and ninth grade teachers, has contributed to the effective implementation of the FGEV into the classroom. Technical accuracy of the FGEV project has been enhanced by a second advisory committee consisting of licensed professional geologists from throughout the state. Measurable effectiveness of the FGEV project has been determined through pre- and post-viewing tests and comment forms distributed to classroom field-test sites. Initial test results and feedback have been very positive. Long-term benefits of the FGEV project can be inferred from the value of education: with a better understanding of geology through the FGEV program, viewers may be in a position some day to make an informed decision about managing or protecting Florida's natural resources.
