Environmental Change Laboratory

The Environmental Change Laboratory (ECL) and its members are dedicated to using the biological, chemical, and physical properties of lake sediment to reconstruct long-term and recent patterns of climate change in the Inter-mountain West of the United States, the central Canadian Arctic and the Ohio River Valley.

The Environmental Change Laboratory (ECL) and its members are dedicated to using the biological, chemical, and physical properties of lake sediment to reconstruct long-term and recent patterns of climate change in the Inter-mountain West of the United States, the central Canadian Arctic and the Ohio River Valley. Our primary objectives at the ECL involve identifying the forcing factors behind long-term and recent climate change, and to trace the impact of these changes on natural ecosystems and people. Lakes are extremely sensitive to local and regional environmental change and we exploit the archival material contained within the lake basins, i.e. sediment, to develop detailed histories of past environmental conditions.

The paleoclimatology and paleolimnology facilities operated by David Porinchu in the Department of Geography at University of Georgia will occupy approximately 1000 square feet on the 3rd floor of the Geography-Geology Building. The ECL, when completed, will include a state-of-the-art paeloenvironmental laboratory dedicated to the study of lake sediment. The paleolimnology laboratory will contain: a Costech elemental analyzer for carbon and nitrogen analyses; a muffle furnace for Loss-On-Ignition analysis; a large drying oven; an analytic balance; cold storage cabinet for sediment core archiving and a full suite of glassware and chemicals. In addition, six Zeiss DV4 Stereomicroscopes are available for chironomid sorting and a Zeiss Axioskop 2 Plus Research Microscope with digital camera and imaging software is available for fossil specimen identification. A reference collection consisting of fossil chironomid remains from the western United States and Arctic Canada and Russia is housed in the lab. A full suite of field equipment is also available, including a YSI handheld dissolved oxygen/ conductivity/salinity/temperature meter, pH meters, inflatable boats, coring platforms and coring equipment (Livingstone and a DeGrand maxi-corer).
