Department Welcomes New





The Chair's Corner
Greetings from Gainesville. We have just closed out a
very successful semester, with the vision of an increase in
appropriations for next year improving morale considerably!
We will also begin the next academic year with a new mem-
ber of our faculty. Raymond Russo of Northwestern Uni-
versity will join us beginning this fall semester. Ray is a
geophysicist with primary interests in global seismology.
Ray will bring active involvement in international geophys-
ics programs to UF, including his current projects in Roma-
nia and Chile. We will introduce Ray further in the next
edition of Rocky Gator.
As we look back on the first semester of our new President's
tenure, it is encouraging to see a fresh look at old problems.
President Machen appears committed to moving the Uni-
versity forward, and clearly recognizes that this can not be

Department Welcomes New


Andrew (Andy) Zimmerman arrived in
Gainesville in January of this year and
has been happily settling in. Andy
comes to us by way of the geological
science departments of The University
of Chicago (B.A.), The University of
Michigan (M.S.), and Penn State (post-
doctoral research) as well as the schools
of marine science at The University of
Texas (research assistant) and William
and Mary (PhD at VIMS). He also spent
a good chunk of time teaching, doing
research and traveling in the Far East.
Since arriving in Gainesville, he has been
busy making renovation and purchas-
ing plans for a new organic geochemis-
try laboratory that will be housed on the
third floor of Williamson. Andy's post-
doc at Penn State involved a teaching
component, which he is putting to good
use with-150 students in OCE 1005, In-
troduction to Oceanography.
Andy's geologic interests began with a
strong interest in sedimentology that
evolved to sediment geochemistry and
then to organic geochemistry and
biogeochemistry and finally
geomicrobiology andnanogeology. His
doctoral research was a study of the
biogeochemical and ecological changes
that have occurred in Chesapeake Bay
over the past five hundred years. For

example, organic geochemical
biomarkers were used to reconstruct the
changes in algal and bacterial
eutrophicationn) since European
settlement in the watershed of that Bay.
His immediate research plans include
the use of organic biomarkers to look
at the ecological changes that have
occurred in some of the coastal regions
of Florida due to human development.
Andy has also become interested in the
relationship between organic matter,
microbes, and mineral surfaces. One
recent set of experiments examined the
effect of mineral nanopores on the
preservation of organic matter in
sediments and soils through the use of
synthesized nanoporous alumina and
silica (see below) and the adsorption
of organic compounds to these
materials. Here in the department, he
will continue research of this type with

studies that move toward examinations
of natural mineral and organic
compound assemblages and include
the addition of microbiological factors
and looking at the results of these
processes in sedimentological and
groundwater settings. While this work
is of a fundamental scientific nature,
obvious applications can be found in
such fields as petroleum science,
contaminant bioremediation, and global
carbon cycling.
The newgeochemistry lab will include
some of the traditional analytical tools
of the organic geochemist; gas chro-
matograph (GC), mass spectrograph
(GC-MS), liquid chromatograph (HPLC),
but also some less traditional tools such
as a laser light scattering detector for
measuring molecular sizes and a gas
sorptometer for measuring mineral sur-
face area and shape. Next year he'll be
offering a class in Organic Geochemis-
try/Geomicrobiology to graduate stu-
dents and taking on a new graduate stu-
dent of his own. He has expressed an
appreciation for the collegiality and
pleasant atmosphere of his new depart-
ment and is learning what Rocky Gator
life is all about.. Football, Beerand Blue-
grass? Also, he reports not to have
missed the winters of Pennsylvania one
little bit.

accomplished without additional funding from all sources. I believe we can expect the announcement of a new capital
campaign n the near future!
In this regard, I want to thank each of you who contributed to the department financially in the 03-04 fiscal year. We are
particularly grateful for the response to our request to move the Anniversary Fund to the next matching level. We are well
on our way to raising the funds that will garner an additional $50,000 of state matching funds. The development of
continuing resources such as those generated by endowments are critical to our department's development. In terms of
how we use these funds, I'm happy to report that we have instituted a new program in which the Department uses
endowment income to provide support for major field excursions. Under this program, any faculty member can utilize GLY
5786L as a stand-alone course or as a companion to an existing course to provide students with an opportunity to visit
special geologic terranes. Right now, the Geology Club is organizing a trip to Death Valley (the geologic one, not Clemson
or LSU!) over next spring break. This will provide an excellent field experience for graduate and undergraduate students,
which would not be possible without your support. Thanks again and have a good summer.

Best wishes,

Paul Mueller

Hi from the Big Apple! (Jennifer Martin, MS 2004) Good news, I finally got a job! I'm a hydrogeologist with Geologic
Services Corporation in Holbrook, NY (on Long Island). Last week was my first week and it went pretty well. There's so much
to learn! I also presented a poster at GSA in Nov 2003 titled: "Establishing the exchange of water between conduits and
matrix in the Santa Fe River Sink/Rise System using water level data." It's finally warming up here thank goodness. I hope
things are going well. Say hi to everyone for me. Jennifer
This is long lost Alex Amigo (Ph.D. 1996) now in California. I am happy to share that Ijust received tenure here, at Sierra
College, and am enjoying every aspect of this work environment. I'm so far away now that visiting you guys looks
harder and harder, but I never lose hope! Cheers, Alex

Lauren Smith, (MS 2004) is with a consulting company (Mactec Engineering and Consulting, Inc.) as an Environmental
Scientist. Located just North of Boston.
Susan Tierney (nee'Kulp) (MS 2003) I'm finishing up my year as the Science teacher at Millhopper Montessori Middle
School (teaching 4th-8th grades); I am teaching two courses for SFCC this summer, Introduction to Environmental Science
and Physical Geology; and will be returning to UF in the fall to complete my Master of Education degree to be certified in
Earth and Space Science at the secondary level.
Matt Smith (PhD, 1999) returned to Gainesville inAugust 2003 when he joined the Department faculty as a Visiting Lecturer.
Matt comes to us from the American Geological Institute (AGI) where he was the Institute's Education Programs Manager.
Matt's responsibilities at AGI centered on curriculum development and k-12 teacher professional development. He was the
project manager and a developer/writer for three NSF-funded middle school and high school Earth Science curriculum
projects. Two of these inquiry-oriented, standards-based curricula (EarthComm-Earth System Science in the Community
and i,.. ,i,,. ,,oi Earth Systems) have been published and are already being used by more than 200,000 students nation-
wide. The third is currently in the final stages of classroom testing.

Matt's primary responsibility for our department is teaching our large-attendance, introductory courses. He is also working
to help the department better meet the needs of students intending to pursue careers as k-12 teachers. Meeting the needs of
these students is particularly important now because there is a great shortage of certified k-12 Earth science teachers in
