We found evidence for
- Long Island Sound Paleo Environments
We have begun a program on the paleoenvironmental history of Long Island Sound which involves faunal, chemical and isotopic studies of LIS sediment cores. We address questions of pollution and changes in water temperature, turbidity and salinity over the last 100-300 years. We address the 'big question': did anoxia / hypoxia occur in LIS prior to industrialization and population increase? We are reconstructing in great detail the environmental history of the 1900's, the last 4 centuries and ultimately, we hope to reconstruct the environmental history of LIS over the last 15,000 years.
Students currently working on the project or starting this summer are Taras Gapotchenko (MA), Polina Rabinovitch, Irina Abramson, Ryan Huggins, and Janna Shackeroff.

(open circles). The d13C* values
are the observed d13C values in foraminifera
tests minus the predicted values based on the mixing characteristics of
LIS and the observed d18O in the
same foram test.
