The Trustees of Grinnell College received a $118,709 Project Grant from the National Science Foundation (NSF) Division of Earth Sciences Geobiology and Low-Temperature Geochemistry Program and Marine Geology and Geophysics Program, under the NSF Geosciences program (CFDA 47.050).

The research project seeks to develop a 1,000-year record of mercury (Hg) concentrations preserved in long-lived mollusk shells collected from the Gulf of Maine. This record will be paired with other climate proxy data preserved in the clam shells to provide detailed information on how marine Hg levels have changed in response to a changing climate. The researchers aim to assess the sensitivity of Hg bioaccumulation to natural climate variability and evaluate biogeochemical-climate models for predicting future Hg trends in marine ecosystems under climate change scenarios. The project will involve collaboration between researchers at Grinnell College and Iowa State University, and provide research opportunities for undergraduate students.
