Paleoceanography and Paleolimnology
Mark Brenner is a limnologist and paleolimnologist with special interests in tropical and subtropical lakes and watersheds. He uses sediment cores from the bottoms of lakes to reconstruct the history of aquatic ecosystems and their drainage basins. (Email; Web Page)
Jason Curtis is a paleoclimatologist who focuses on Holocene and latest Pleistocene climate and environmental changes. Much of his work involves stable oxygen and carbon isotopes preserved in carbonate microfossils from tropical lake sediments. Currently he is analyzing material from the lakes in the Amazon basin, Crete, Mexico, and Guatemala. (Email; Web page)
David Hodell's research focuses on using sediment
cores collected
from lake and ocean bottoms as well as speleothems to reconstruct past
changes
in Earth's climate, oceans, and environment. His specialty is the
application of stable isotopes (oxygen, carbon, nitrogen,
strontium) to
study a broad spectrum of geologic problems including paleoclimatology,
paleoceanography, paleolimnology, geochemical cycling, and
stratigraphy. His
active deep-sea research programs include material collected on IODP
Expedition
303 (North Atlantic), and ODP Legs 208 (Walvis Ridge) and 177 (Southern
Ocean). Ongoing lake sediment core and
speleothem research is focused on Cambodia and the Maya lowlands of
Guatemala
and Mexico (Email;Web Page)
John
Jaeger examines the role
of
glaciomarine processes in high-latitude marine sedimentation, landscape
evolution, and modern climate change reflected in glacier dynamics. A
range of
sedimentological, mineralogical, and chronological tools are used to
quantify
the role of glacial processes affecting margin sedimentation in the
Gulf of
Alaska. (Email;

Ellen Martin uses radiogenic
isotopes in marine sediments to
study
the relationship between ocean circulation and climate over a wide
range of
time scales from the Permian to the Pleistocene. In particular,
Martin is focusing on the effects of major gateway
events such as the opening of the Drake Passage and the closure of the
Isthmus of
Panama. (Email; Web Page)
