The Keene Faculty Center
Our faculty have long deserved a
place of their own. Since last November,
they have had just that in the form of the
Keene Faculty Center, located in Dauer
Hall. If you have not seen this facility
and taken advantage of it, do yourself a
favor and come by for a visit.
The Keene Faculty Center, argu-
ably one of the most beautiful venues
on campus, was designed to provide an
attractive, inviting space for faculty to use
in a variety of ways. First and foremost,
it is a quiet get-away spot where fac-
ulty can retreat to read, converse with
other faculty, or simply relax between
classes. A Java Hut cart in the lobby
serves specialty coffees, teas, and bagels.
Packaged lunches are available for those
who frequent the Center at mid-day, but
you should also feel free to brown-bag it.
Inside the Center, you will find the New
York Times and Gainesville Sun available
daily and the Chronicle of Higher Educa-
tion weekly. The Ethan Allen chairs and
couches are plentiful and comfortable.
You can even plug in your laptop and
access the internet. And if there are other
things you would like to see in the Center
(affordable by CLAS), let us know. We
have a Faculty Advisory Group to provide
input, but we welcome individual com-
ments as well.
In addition to the large ground floor
of the Keene Faculty Center, the facility
features a spacious gallery overlooking
the main hall. Here smaller meetings can
be held, including lunches of up to about
15 people. A reconditioned baby grand
piano is available in the gallery for recit-
als. Indeed, the acoustics of the Keene
Faculty Center make it an attractive
venue for chamber music performances.
Note that this is not a Faculty Club.
There are no dues, nothing to join, no

From the Depths of the Earth

Geologist David Foster studies birth and death of mountains


Though the Bitterroot Mountains on
the Montana-Idaho border may not
be as flashy as some-at 10,200
feet, the range's tallest peak is hardly a
Denali, much less an Everest-geologist
David Foster considers them one of the
most important mountain ranges in North
America.
"The Bitterroots are interesting because
they expose rocks that formed in the
earth's middle crust at depths somewhere
around 20-30 kilometers (12-18 miles) be-
low the surface," Foster says. "The rocks
formed there mainly between 90 and 50
million years ago when Western Montana
was part of a mountain range (known as
the northern Sevier Orogen) more like the
Andes, much higher and more extensive
than it is today."
Fifty million years ago, the Sevier Moun-
tains were torn apart by the extension or
thinning of the continental crust. As the
earth's crust thinned and the mountain belt
collapsed, portions of the middle crust
were transported upward to the surface on
very large faults that are well exposed in
a flank of the Bitterroot Range. "So by
studying this mountain complex," explains
Foster, "we can understand what happens
at the middle part of the crust during the
formation and destruction of many large
mountain ranges. Additionally, we can use
the Bitterroots as a proxy for what's now
going on deep within the crust in the Andes
or to understand what's occurring within
the mountain ranges of the Himalayas and
Tibetan Plateau."
This is especially valuable, says Foster, be-
cause recent evidence indicates that in Ti-
bet, the middle crust is unusually thick and
has build up enough heat that it may have
started to partially melt. The presence of
magma could weaken the crust enough that
the mountain belt may eventually collapse,
mimicking the evolution of the Bitterroots.


Foster is pictured above using GPS (Global
Positioning System) to obtain the location
of a sample from the Bitterroot fault zone.
GPS uses signals from 12 satellites to
calculate specific locations.


During the collapse phase of a mountain
belt, the chances for large earth quakes,
volcanic eruptions, landslides and other
large scale geological hazards are greater
because the rate of movement on faults is
more rapid. "Certainly the recent events
in Turkey are a reminder of just how
unstable the earth's crust is," says Foster.
"In the middle crust, rocks are the bound-
ary between where layers of the crust fail
and break by brittle fracture at shallower
depths and where they start to flow like
plastic at deeper levels," he explains. "It's
a natural breaking point." Since many of
the large earthquakes along major faults
like the San Andreas are propagated from
the same mid-crustal depths Foster studies,
his work may potentially help pinpoint
new areas prone to earthquakes or other
geological disasters.
Foster's tectonic research is not restricted
to Montana. "Over past eight to ten years
I've been working on a very large scale
project aimed at reconstructing the evolu-

English
Chris Snodgrass was invited to write the special 100-year
retrospective on scholarship about Aubrey Beardsley, a major
late-Victorian artist whose Centennial year was 1998. This long
essay, which was also responsible for assessing the position of
Beardsley in current Victorian studies as well as reviewing all
recent scholarship on Beardsley, appeared as the lead article in
English Literature in Transition, 1880-1920.

History
Geoffrey Giles was a Fellow this summer in the US Holocaust
Memorial Museum's first Research Workshop for Scholars. The
eight participants spent two weeks at the museum's Center for
Advanced Holocaust Studies in Washington, DC, discussing
papers and carrying out further research in the Center's archives
and library, as well as in the National Archives. The theme of
this first workshop was "SS Racial Policies in Occupied Eu-
rope."

Philosophy
Greg Ray presented a paper entitled "Is There a Problem about
Vagueness?" coauthoredd with Kirk Ludwig) at the annual meet-
ing of the Society for Exact Philosophy, Lethbridge, Canada,
in May. Ray will host the next meeting of this international
organization here at UF

Kirk Ludwig presented his paper "Logical Form" at the annual
meeting of the Society for Exact Philosophy. Dr. Ludwig pre-
sented the coauthored paper "Is There a Problem about Vague-
ness?" at the Pacific Meeting of the American Philosophical
Association, held in Berkeley, California, in April.

John Biro, president of the Hume Society, presented the paper
"Hume on Memory" at the Society's annual meetings in Ireland
in July. In August he gave a series of lectures on fallacies at the
University of Turku, Finland. He is coediting a volume of es-
says on Spinoza to be published this year by Oxford University
Press.

Psychology
Robin Lea West, Director of the Center for Gerontological
Studies, gave an invited address at the American Psychologi-
cal Association (APA) meeting in Boston in August, 1999. Her

History Lecture Series Created in
Memory of Gus Burns
In order to recognize the outstanding contributions of "a
master teacher and scholar," friends and col-
leagues of history professor Gus Burns, who
died April 30, 1999, have established an annual
history lecture series in his name. "It is our
hope that the Gus Burns Memorial Lecture
Fund will attract outstanding scholars to the
University of Florida," says Florida Studies
Director Julian Pleasants, a long-time colleague
of Burns. Each invited scholar will give one
public address and will also meet with graduate and undergradu-
ate classes. Tax deductible donations to the fund (#007613) can
be made through the University of Florida Foundation.

CLAS Computing: Web Help for Faculty


A message from Jack Sabin,
CLAS Director of Information Technology


It's time to welcome two
more folks to the CLAS
technology fold.
As you know, we are continu-
ally encouraged to upgrade the
level of technology that we
use in our teaching and service
activities. For example, all
faculty now have a Gatorlink
account, which will soon be the
only possible method for sub-
mitting grades. Please note that
your Gatorlink e-mail address,
which you automatically get
with your account, is the only
address usually listed in the UF
directory, so it's important, if
you don't use your Gatorlink
mail, to have it auto-forwarded
to one of your active accounts.
This is very easy to do quickly
online at edu>.
Another aspect of our increas-
ing integration of technology
into our jobs is the use of Web


based resources in classes and
the proliferation of educational
Web pages. We UF profes-
sors are now expected to have
a Web page for each course,
containing the syllabus at a
minimum. Soon these pages
will be connected to the UF cat-
alogue by hot links, so prospec-
tive students or those register-
ing online can access course
content in real time. Examples
of the beginnings of these
pages can be found at reg.ufl.edu/99-20catalog/coll-
liberal-arts.html>. In addition
we are encouraged to use the
Web and e-mail to interact with
our students.
Many faculty and graduate
students also have professional
personal Web pages, normally
accessible from their depart-
mental home pages, which offer
contact information and details
about their professional lives,


publications, etc. Examples
can be found at edu/users-dept.html>.
Preparation of a personal
or class Web page is not, in
principle, difficult, as there
is a plethora of editors avail-
able that help in writing the
HTML (Hyper Text Markup
Language). In addition, OIR
provides courses each semes-
ter in Web page preparation
at the Faculty Support Center.
We highly recommend that, if
you are an HTML novice, you
attend an OIR training session
and become familiar with the
basics of Web page prepara-
tion. The problem here is that,
after you learn how to prepare
a Web page at the Center, you
may have a different machine
in your office running differ-
ent software than that used in
the training session. To help
you over that barrier, we have


Jack Sabin


hired two undergraduate Web
experts, who will come to your
office and help you adapt the
information you learned at the
OIR course to your office sys-
tem. These students will work
out of UCET and be supervised
by Dr. Connie Shehan. They
will each be available several
hours a week starting imme-
diately. You may make an ap-
pointment to have one of them
visit you by calling 846-1574.
Let me introduce them to you:


Amano Kazumi

"In my new position, I
look forward to helping
CLA S faculty create
and maintain effective
Web pages."


Amano (Joseph) Kazumi (Douze) is a fifth year senior
from West Palm Beach majoring in East Asian languages
and literatures, with a Japanese concentration. In addi-
tion to making personal Web pages as a hobby, Kazumi
worked at CIRCA for four years and has been a Webmas-
ter at the college of business for three years.


Meghan Gill is a junior from Boca Raton majoring in deci-
sion information systems (computer programming and busi-
ness) and international economics. Her experience includes
Cobal and Programming in C, and she does database manage
ment for the Alzheimer's Association.



"I am really excited to
get the chance to work
with the faculty as well
as improve my com-
puter skills."

Exploring the Ocean Floor

An interview with Elizabeth Screaton, Geological Sciences |m W' M


Cn: What is your geological area of specialty?
ES: I am a hydrogeologist-one area that I work on is water and
plate tectonics and the role of fluids at subduction zones on the
ocean floor (where an oceanic plate slides under another tectonic
plate).

Cn: How do geologists track how these giant plates move over
time?
ES: We combine a lot of different methods to get a clear profile
of what is happening and what has already happened. We use
remote methods and geophysical methods (looking at the source
areas of earthquakes allows you to track the subducting plate).
Closer to the surface, we can actually use seismic reflections, in
which we create a shaking that is transmitted through the earth
and it bounces off the boundaries between layers and comes
back up to the surface giving us an image similar to an ultra-
sound. This allows us to get a look at what's down there without
drilling into it.
We can estimate how much sediment is being subducted,
and we've got an idea how much water is in that sediment. We
know that the fluid has to be getting out somehow when the sedi-
ment is compacted, so we use computer models to tell us what
ways are possible for it to be getting out, and how that's going to
affect pressures. Fluid pressures play an important role in allow-
ing plates to slide past each other and in generating earthquakes.
We can drill holes at these sites to take a look at core sam-
ples. We also make observations by going down to the seafloor
[see MBARI photographs in Jon Martin's article, page 7]. At
this level, you can locate places where you've got fluid expul-
sion because you often get communities of clams and sometimes
tube worms that live there and feed off the methane and hydro-
gen sulfide that gets carried up in the water.

Cn: Are certain areas of the ocean floor more desirable to work
on?
ES: A lot of areas around the world have active subduction
zones (the Ring of Fire, for example), and many of these areas
are being worked on by different people. The area under Japan,
for example, is fairly well marked out. Dr. Perfit (Geology)
is working along some of the ridges where new ocean plate is
forming, and I am looking at the other end, where a plate is
disappearing.


Cn: How do geologists travel to
these areas?
ES: There is currently only one
large drilling ship, so the whole
international community of geolo-
gists splits up time. The year is
divided up into six two-month
trips-only six a year-so when
you apply for time, you have to
make a really strong case as to
why this is an important place to
study and what scientific goal it
fulfills. There are a lot of different
aspects to drilling the ocean floor
that compete for the ship's time (besides subduction issues) such
as studying paleoclimates (ancient climates). Dr. Hodell (Geo-
logical Sciences) works in this area, which helps us to understand
how climate might change in the future.

Cn: Do geologists hope to be able to predict earthquakes eventu-
ally?
ES: I don't know if we will ever be able to predict an earthquake
like a weather forecast, but we hope be able to say what areas are
ready for or overdue for an earthquake. We also hope to find out
why some earthquakes generate tsunamis, and why others don't.
Tsunamis depend on some sort of disruption in the seafloor that
acts as reason to start the wave.

Cn: On a completely different note, you're also doing ground-
water work here in Florida, right?
ES: Yes, I'm starting a project going with Jon Martin right now
to look at (among other things) what happens at the Santa Fe
River between where it disappears underground and comes back
up. When the water goes down and comes back up, is it the same
water? Is it mixing with the ground water around there? What
does that mean for its vulnerability to contamination from surface
water? The aquifers around here are pretty important to us, so this
should be a really interesting project.%

centrations of carbon dioxide and methane, both greenhouse gases. Consequently, circulation through subduction zones may play a
role in the greenhouse warming of the earth. The volume of water and gases venting from subduction zones is poorly known because
individual vents are small, although widespread. Continued research should ultimately define the volumes of water and gas that vent
from subduction zones.
Although geology can be broken into many sub-disciplines, including hydrogeology, essentially all geologists working on recent earth
processes study the physical and chemical effects of water on the earth. As such, water is probably the most important, however im-
probable, of all geological materials.%

tion of eastern Australia, from the time
sediments were deposited on the ocean
basin some 500 million years ago through
a series of large collisions between that
continent and oceanic island chains that
occurred between 440 and 300 million
years ago. During all of this time Australia
was part of the super-continent of Gond-
wana, attached to India, Antarctica, Africa,
and South America."
Those collisions formed major moun-
tain ranges in eastern Australia, which,
now worn down and nearly flat, contain
some of the largest gold deposits in the
world. "Our main objective is to examine
the evolution of the mountain belts there
because they are an ancient example of
the current geologic activity in southern
Alaska, but secondary follow-up research
allows mineral companies to pinpoint areas
where exploring for gold and other miner-
als would be more prospective."
But tectonics work is only half of what


Foster does. He also utilizes tempera-
ture-sensitive isotopic dating methods
or 'thermochronologic methods' in his
research, allowing him to measure the
temperature and time history of rocks.
"Since most geological processes involve
heat," he explains, "if we know when a
rock was at certain temperature, it tells us
about how it formed and about the history
of the mass of rocks around it. This tech-
nique also gives us insight into the whole
mountain building process, the extension
and breaking apart of the continents, and
the erosion process."
As part of the renovation of their new
home in Williamson Hall, Foster and his
geological sciences colleagues plan to
establish a thermochronology lab here at
UF. "The lab will feature a large mass
spectrometer for measuring noble gases,"
Foster says, which will work in tandem
with two other proposed labs that use
additional thermochronological methods.
"Each lab will allow us to -
look at different tempera-
ture intervals of a rock's
thermal history. We'll be


able to track the history
a rock from temperatures
of >500C to, effectively,
surface conditions. Most of
the lab applications will be
to look at tectonic process-
es, but the lab will also be
used to help the petroleum
industry determine which
sedimentary rocks are pro-


spective for petroleum exploration."
The other thing these labs will be able to
do, says Foster, is to date the precise age
of volcanic eruptions, which will help es-
tablish the age of many geological events,
as well as determine the periodic eruption
intervals of certain volcanoes. Resulting
research will also help geologists to under-
stand the age of different parts of the sea
floor and to date fossil localities, particu-
larly Hominoid sites.
The department has made fundraising
for the new labs a priority. "We're partly
funded by UF, but we're seeking external
matching funds from NSF or other outside
sources for the remainder," says Foster.
"In the next two years, we hope to have all
this up and running."%

Water and Geology


An improbable but important link
by Jon Martin, Department of Geological

Most people probably think of a geologist as someone
myopically focused on rocks, not water. But water
influences the physical and chemical evolution of the
earth (the essence of geology), probably making it the most im-
portant material in all geological processes.
The influence of water can be seen in many common processes,
such as erosion of mountains through stream runoff, slow grind-
ing of glaciers, and frost wedging during freeze-thaw cycles. A
good Floridian example of the erosive power of water comes
from the destructive force of hurricanes (I am writing this article
during my forced evacuation from Turlington Hall because of
Hurricane Floyd). In addition to causing erosion, however, water
is important as a precious commodity similar to another valuable
liquid, oil. For example, Florida's economy is essentially based
on water, from tourism to
to agriculture. And like oil,
more than 95% of all fresh
water is located under-
ground, leading to many
important problems.
Most water in Florida
is located in a group of
limestone rocks, called
the Floridan aquifer, that
provides nearly all water
for drinking and irrigation

and leads to the wide-
spread formation of a landform called karst. Karst is common to
Florida and makes the state world-renowned for cave diving and
sinkholes. Karst also leads to a series of interesting questions that
I have been working on lately, such as how and at what rate does
water infiltrate the aquifer, where does it flow through the subsur-
face, and what are the resulting chemical changes to the water and
rocks during its flow?
A common belief among karst hydrogeologists (geologists
interested in water flow through karst areas) is that caves act as
primary reservoirs and flow paths for water in the subsurface.
This belief, now almost dogma, comes about because most well-
studied karst occur in old regions (more than 150 million years)
of North America and Europe. Some of my recent work shows,
however, that the relatively young Floridan aquifer (about 55
million years old) does not behave this way. Instead water flows
through the Floridan aquifer in both large conduits and micro-
scopic pore spaces contained within the matrix rocks surrounding
the caves. The difference between the Floridan and older karst

aquifers appears to result
from recrystallization and
loss of porosity of the
older karst rocks. The
distinction between water
flowing in conduits versus
matrix may seem trivial,
but it is very important John Martin (left) with fellow

remains underground,
referred to as residence
time. Residence time, in turn, controls the extent of dissolution
and the frequency of cave and sinkhole formation. It also controls
the distribution of pollutants that flow into the aquifer along with
the recharged water. And ultimately, it controls where those pol-
lutants emerge back to the surface, for example, in springs, estuar-
ies, or perhaps your kitchen sink.
Many other important geological processes involve water, but are
rarely experienced in everyday life. A good example is provided
by hydrothermal vents at mid-ocean ridges. These submarine
springs are sufficiently active to circulate all seawater through the
crust every ten years. This process changes the chemical compo-
sition of the water, and thus controls the concentration of salts in
seawater, supports non-photosynthetic biological communities,
and because conditions at the vents are similar to those of the
early earth, may have provided the setting for the origin of life.
Less commonly known, however, is that water is also important
at subduction zones, the other end of the plate tectonic conveyor
belt. In these areas, high water pressure lubricates faults and
allows the plates to slide freely past each other. Most free water
is squeezed from the rocks
by about 13 km below the
surface. At this point rocks
can break brittlely, caus-
ing large earthquakes with
catastrophic results, such as
the recent events in Turkey
and Greece.

of my research thus in-
volves trying to understand the mechanisms that drive water from
the rocks, to determine the origin of this water, and the volume of
the water that is vented. It is possible that some of the water vent-
ing from subduction zones is recirculated seawater, similar to the
mid-ocean ridge hydrothermal vents, in which case subduction
zones could play an important role in the chemical evolution of
seawater. Subduction zones also commonly contain high con-

New Chair

Chris Stanton, Chair
Physics Department
A s we approach the year 2000 and look back at the scientific achievements impacting society over the
last 100 years, it is safe to say that physics has played a major role. While the role of physics is
obvious in areas such as the development of the transistor and laser, it is less obvious in other realms.
t For instance, fundamental research in solid state, atomic and nuclear physics has lead to the development of
modem medical imaging techniques such as Computed Axial Tomography (or CAT Scan), Magnetic Reso-
nance Imaging (MRI), Ultrasound, and Positron Emission Tomography (PET Scan). The Global Positioning
System or GPS resulted from research designed to test Einstein's theory of relativity. The $1.5 trillion/year
telecommunications industry responsible for the information super highway was aided by early physics research. Physicists developed
new materials, electronics and lasers, which in turn lead to fiber optics and cellular communications. In addition, though not well
known, particle physicists designed the World Wide Web as a means for scientific communication with colleagues.
It is clear that physics will play a fundamental role in many of the new technologies that emerge in the next century. It is our goal
as a department to train and educate the students who will be making contributions and competing in a highly technical society. To
meet that goal, the department has changed dramatically in the last 20 years. When I was an undergraduate student here in 1979, the
department had 22 faculty members. Today, we have over 50 tenure track faculty members, almost half of whom were hired since the
fall of 1988. The excellence of our faculty is demonstrated by the fact that the department has had six National Science Foundation
Presidential Young Investigator/Early Career Award recipients, two Cottrell Scholars, two Sloan Fellows, three Guggenheims and two
Jesse Beams Medal winners. The recruitment of faculty has enabled the department to establish active research groups in astrophys-
ics, cosmology and gravitation, condensed matter physics (experimental, theoretical and computational), low temperature physics, el-
ementary particle physics (experimental and theoretical) and more recently biophysics. Excellence in the faculty has translated down
to excellence in our students. Two of our undergraduate students have been finalists for the American Physical Society Apker Award
(given to the top research project by an undergraduate student in the US) with one student winning the award outright.
These improvements have enabled our department to move into the top quarter of all physics departments nationwide according
to the National Research Council's rankings. Like the university as a whole, however, we are not content with this level of distinction
and want to move onto the list of top 10 public university physics departments. The New Physics Building will be a valuable resource
in attaining this goal. In addition, we must continue to recruit the best faculty from around the world, and to increase our external
funding. This will allow us to further improve our graduate and undergraduate programs while securing our position at the forefront
of research.

Research and Management Tech-
niques for the Conservation of Sea
Turtles
Edited by Karen L. Eckert, Karen A.
Bjorndal (Zoology), F. Alberto Abreu-
Grobois and Marydele Donnelly
Marine Turtle Specialist Group

(from preface)
To ensure the survival of sea turtles,
it is important that standard and ap-
propriate guidelines and criteria be
employed by field workers in all range
states. Standardized conservation and
management techniques encourage
the collection of comparable data and
enable the sharing of results among
nations and regions. This manual
seeks to address the need for standard
guidelines and criteria, while at the
same time acknowledging a grow-
ing constituency of field workers and
policy-makers seeking guidance with
regard to when and why to invoke one
management option over another, how
to effectively implement the chosen
option, and how
to evaluate suc-
cess.

(excerpt)
Knowledge of
the effects of
human activities
on sea turtles in
foraging habi-
tats are clearly a high priority for the
management and conservation of sea
turtles. Current levels of directed take
of sea turtles on foraging grounds and
the effect of these harvests on popula-
tion stability should be assessed. The
opinion that sea turtle populations
can sustain harvests on their foraging
grounds as long as they are protected
at their nesting beaches reflects a lack
of understanding of just how unrelent-
ing and efficient such harvests can be.


Reputations of the Tongue: On Po-
ets and Poetry
William Logan (English)
University Press of Florida

(from book jacket)
William Logan is the most dangerous
poetry critic
since Randall
Jarrell. Intense ...
and savagely
witty, he is the
most irritating
and strong-
minded reviewer
of contempo- ON nya ou ND POETm Y
rary poetry we
have. A survey
of American,
British, and Irish poetry in the eighties
and early nineties, Reputations of the
Tongue is a book of poetry criticism
more honest than any since Jarrell's
Poetry and the Age....
Logan's reviews have been noted
for their violence, intelligence, candor,
and humor. Many aroused tempers on
first publication, leading one Pulitzer
Prize winner to offer to run the critic
over with a truck.

(excerpt)
A book of selected poems is a monu-
ment to middle age. It may revive a
flagging career or embalm an overval-
ued one. As a sign of respectability,
or as a device to return to print poems
long out of it, a selected poems is an
unendurable temptation for poets who
have not received their due (and even
great poets fear they have not received
their due). Though a clever poet can
obscure his old sins or alter his allianc-
es (early Yeats, in our standard texts,
is often late Yeats in sheep's clothing),
revising with a liver-spotted hand the
radical errors of youth, these monu-
mental designs usually falter, like those
of public statuary, between ingratiation
and ingratitude. Most poets should
rest on their laurels or read their old
reviews.


Book Beat

Native Americans in Florida
Kevin McCarthy (English)
Pineapple Press

(from book jacket)
The book begins with a discussion of
several basic areas of interest to those
studying Native Americans in Florida.
The author explores the importance of
archaeology in preserving the past for
future generations, how archaeologists
do their work, and even how young
people can gain hands-on experience
on a real dig. The different types of
Indian mounds-burial mounds, shell
middens, and platform mounds-and
their uses are explained, as well as
Indian languages and reservations.

(excerpt)
Today in Florida only two languages
are still spoken among the Seminole
people. These are Mask6i (erroneous-
ly called "Creek" by English speakers)
and a Hitchiti dialect called MisiksDki.
But 50 years ago, seven languages
were still in use, and 150 years ago,
there may have been a dozen or more.
The only trace of the original lan-
guages spoken
in Florida for
several thou-
sand years is
in a few place
names that the
Europeans bor-
rowed from the
Indians. It was
usually easier for
the new explor-
ers to use an Indian name for a lake,
river, valley or settlement than to make
up a new name. The Europeans might
ask friendly Indians what they called a
certain place. The Indians would tell
the Europeans what the Indian name
was, and the Europeans would listen to
the word and then pronounce it in their
own language as close to the Indian
pronunciation as they could.

responsibilities. It was funded by private
support by Mr. and Mrs. Kenneth Keene,
with state matching funds. By use of
non-state monies, we were able to cre-
ate a Faculty Center of unusual beauty
and quality, in keeping with the Keenes'
wishes. The room itself goes back to
1937, when it was built as part of the
first UF Student Union, which eventually
became the Arts and Sciences Building
and later, Dauer Hall. In its earliest days,
the Center was known as the University
Banquet Hall, but archival photos show
many types of events taking place there
in the 1940s and 50s. Thus, a rich history
precedes its reincarnation as the Keene
Faculty Center.
In addition to individual use by
faculty, the Keene Center finds extensive
demand as a site for dinners, lunches,
receptions, and various types of organiza-
tion activities. Its popularity is grow-
ing rapidly. Associate Dean Joe Glover
oversees the Center, schedules events,
and makes appropriate decisions for its
use. Please see him if you have questions
or take a look at the Keene Faculty Center
Web site
for more information.
Soon we will begin Phase II of the
Center renovation process, which will add
more hardwood floors in the upper lobby
and extend this treatment down the Dauer
hallway to connect with the McQuown
Room, a site for smaller meetings and
conferences. Future plans call for devel-
opment of a landscaped courtyard to the
north of the Keene Faculty Center.
The Center is sponsored and funded
by CLAS, but we encourage participa-
tion by those from other colleges as well,
so that it may serve as a central meeting
site for faculty across UF I hope you are
already enjoying and taking advantage of
the Keene Faculty Center, a rare and mar-
velous facility that recognizes and honors
our faculty.
See you at the Keene.

A Note From the Chair

Paul Mueller, Chair
Geological Sciences

T he Geological Sciences constitute a diverse
array of disciplines directed towards improv-
ing our understanding of the origin and his- -
tory of the Earth and the life it holds. True to this
definition, faculty and students in the Department of
Geological Sciences pursue research and teaching H
programs ranging from climatology to volcanology.
Taking the broad definition of life to include homo
sapiens, we also study humankind's influence on our
planet, including the impact of our continuing pursuit
and consumption of non-renewable natural resources;
the implications of geologic systems and hazards for land use (e.g., sinkholes, ground-
water contamination, etc.); and the debate about global warming. In order to meet these
challenges to our future, the Department of Geological Sciences has developed well inte-
grated educational and research programs that address the most fundamental and topical

issues in the earth sciences. Current areas of
emphasis include geochemistry, geophysics,
hydrology, and environmental geology. We
also have begun to develop a new instruction-
al/research program that focuses on the his-
tory of the Earth from a systems perspective,
and emphasizes studies of ancient climates as
a guide to understanding how anthropogenic
activity may affect our planet's future.
Growing enrollments in our graduate and
undergraduate courses, strong interest in our
graduates from employers in Florida and
nationally, and record levels of extramural
support of both our research and instruc-
tional programs speak to the quality of these
programs. Most recently, our research efforts
in geological oceanography were recognized
in the form of an invitation to become one of
only 14 institutions that comprise J.O.I. (Joint
Oceanographic Institutions). J.O.I. oper-
ates the $46M Ocean Drilling Program (the


world's largest multi-national earth science research program) for the National Science
Foundation. In addition, we are implementing a $1,000,000 National Science Founda-


tion grant to renovate research space in
Williamson Hall that will cap a gratify-
ing year that began in late 1998 with a
celebration of the 50th anniversary of an
independent Department of Geological
Sciences at the University of Florida. The
next fifty years will no doubt prove most
interesting for our students and faculty as
they strive to meet the challenges posed by
the ever increasing demands that society
places on our planet.%
