Student Analyses Cores to Document Lake Level Changes
Geology major Lacy Folga began her Research In Geology project this semester with a trip to take sediment cores in the DEC Catherine Creek Wildlife Management Area south of Watkins Glen, New York. The core site was a wetland at the south end of Seneca Lake (the second largest of the Finger Lakes). The goal of the study is to compare these sediments with cores taken in the lake itself to piece together a history of lake level change, as well as an ecological history of the region since the last glaciation. The research is being done under the supervision of Dr. Rayburn.
Now that she has the cores, Lacy will be busy in the lab working on organic carbon content, inorganic carbonate content, and particle size analysis. Next semester Lacy will take samples from the cores to the United States Geological Survey's national headquarters in Reston, Virginia to extract and identify pollen.
