Mark Marvin-DiPasquale, PhD
Dr. Marvin-DiPasquale is a Research Microbiologist for the USGS Water Resources Mission Area.
A native of Rochester NY, Dr. Marvin-DiPasquale is Project Chief in the Water Mission Area (WMA) Earth System Processes Division (ESPD). He is the science lead of the "Microbial Biogeochemistry” workgroup and the project manager of the WMA "Proxies Project". He completed a B.S. in Chemistry at SUNY StonyBrook in 1987 and a Ph.D. in 1995 from University of Maryland, Marine and Estuarine Environmental Science Program, with a focus on the microbial ecology of Chesapeake Bay sediments. He began a career at USGS (Menlo Park, CA) as a ‘National Research Council’ post-doc in 1995, and became a Project Chief in 2004. During much of his USGS tenure, his research focus has been on mercury cycling in various ecosystems, including: the San Francisco Bay watershed and associated mining areas throughout CA; FL Everglades; Carson River, NV (mercury Superfund site); coastal Louisiana; Patagonia region of Argentina; Puget Sound, WA; USGS-NAWQA and USGS-WEBB Study Units in OR, FL, WI, SC, NY, CO, GA, PR, and VT.
Research Interests: microbial ecology, biogeochemistry, estuarine and freshwater ecology, mercury and other trace metal biogoechemistry

Sources of mercury to San Francisco Bay surface sediment as revealed by mercury stable isotopes Sources of mercury to San Francisco Bay surface sediment as revealed by mercury stable isotopes
Mercury (Hg) concentrations and isotopic compositions were examined in shallow-water surface sediment (0–2 cm) from San Francisco (SF) Bay to determine the extent to which historic Hg mining contributes to current Hg contamination in SF Bay, and to assess the use of Hg isotopes to trace sources of contamination in estuaries. Inter-tidal and wetland sediment had total Hg (HgT)...

Spatial and seasonal variability of dissolved methylmercury in two stream basins in the Eastern United States Spatial and seasonal variability of dissolved methylmercury in two stream basins in the Eastern United States
We assessed methylmercury (MeHg) concentrations across multiple ecological scales in the Edisto (South Carolina) and Upper Hudson (New York) River basins. Out-of-channel wetland/floodplain environments were primary sources of filtered MeHg (F-MeHg) to the stream habitat in both systems. Shallow, open-water areas in both basins exhibited low F-MeHg concentrations and decreasing F-MeHg...

Geophysical bed sediment characterization of the Androscoggin River from the former Chlor-Alkali Facility Superfund Site, Berlin, New Hampshire, to the state border with Maine, August 2009 Geophysical bed sediment characterization of the Androscoggin River from the former Chlor-Alkali Facility Superfund Site, Berlin, New Hampshire, to the state border with Maine, August 2009
The former Chlor-Alkali Facility in Berlin, New Hampshire, was listed on the U.S. Environmental Protection Agency National Priorities List in 2005 as a Superfund site. The Chlor-Alkali Facility lies on the east bank of the Androscoggin River. Elemental mercury currently discharges from that bank into the Androscoggin River. The nature, extent, and the speciation of mercury and the...

The effects of sediment and mercury mobilization in the South Yuba River and Humbug Creek confluence area, Nevada County, California: Concentrations, speciation, and environmental fate – Part 1: Field characterization The effects of sediment and mercury mobilization in the South Yuba River and Humbug Creek confluence area, Nevada County, California: Concentrations, speciation, and environmental fate – Part 1: Field characterization
Millions of pounds of mercury (Hg) were deposited in the river and stream channels of the Sierra Nevada from placer and hard-rock mining operations in the late 1800s and early 1900s. The resulting contaminated sediments are relatively harmless when buried and isolated from the overlying aquatic environment. The entrained Hg in the sediment constitutes a potential risk to human and...

The effects of wetland restoration on mercury bioaccumulation in the South Bay Salt Pond Restoration Project: Using the biosentinel toolbox to monitor changes across multiple habitats and spatial scales The effects of wetland restoration on mercury bioaccumulation in the South Bay Salt Pond Restoration Project: Using the biosentinel toolbox to monitor changes across multiple habitats and spatial scales
The project was initiated in April 2010, and to date has included four sampling events of surface water (April, May, June/July, and August 2010) and five sampling events of biota (April, May, June/July, August, and September 2010) and three sampling events for surface sediment (May, June/July, and August 2010). This annual report briefly summarizes our progress to date.
