Research Webinar: Mercury bioaccumulation in the deep and shallow basins of Lake Champlain

In LCSG's third spring research webinar, Dr. Vivien Taylor from Dartmouth College will present her Lake Champlain Basin Program research findings on mercury concentrations in Lake Champlain. Lake Champlain is a fascinating system to study mercury because of the variation in biogeochemical properties across its distinct basins. In this research, Dr. Taylor and her team investigated concentrations of mercury in game fish across all seven basins of the lake, compared them to data from previous years, and used stable isotopes of mercury, carbon and nitrogen to assess the sources and processes driving mercury bioaccumulation in the lake. They also compared seasonal trends in mercury in the water column and in zooplankton across the deep and shallow basins, showing the hypolimnia of the deep basins to be zones of heightened bioaccumulation.

Participants should expect approximately 30 minutes of presentation, which will be recorded, followed by a facilitated, 30-minute Q&A period.
