Presentation on Mercury in Cores from San Francisco Bays and Wetlands

Don Yee presented at the RMP Hg Meeting on the results of the Mercury coring study. Cores collected at 11 subtidal sites, distributed throughout the Bay, were studied to determine ages and pollutant chemical concentrations of various layers. The research showed that mixing is on-going in bay sediments, so there are likely no large deposits of pollutants waiting beneath the surface, however depositional wetland cores show continual loading of pollutants throughout the years.
