The work being described in this report represents the second phase of mercury investigations in the Bay-Delta Estuary. The primary goal of this project was to provide an integrated research project on sources and loads of mercury in the Bay Delta watershed, and the transport, cycling and transformation that occur to mercury and monomethylmercury within the watershed. This research project was designed to evaluate mercury sources and sinks and biogeochemical cycling using a mass balance approach. The objectives of this research program expanded upon previous findings to: 1. Fill in data gaps in our current conceptual understanding of Hg and MMHg sources, sinks, and cycling in the Bay-Delta and its watershed; 2. Verify and quantify seasonal variations of MMHg in sediments and in the water column with respect to habitat type; 3. Accurately characterize the spatial distribution of total Hg and MMHg in the Delta; 4. Estimate the loadings of MMHg from wetlands and evaluate their importance relative to other sources; 5. Provide a foundation and framework for long term monitoring of Hg contamination issues in the Delta.
