From May 3 to May 11, 2017, the U.S. Geological Survey, in collaboration with the British Geological Survey and with support from these two agencies, the National Oceanic and Atmospheric Administration (NOAA) Office of Ocean Exploration and Research, and the U.S. Department of Energy, will lead an expedition aboard the R/V Hugh R. Sharp to explore seafloor methane seeps on the northern U.S. Atlantic margin between Baltimore Canyon and Cape Hatteras

For this expedition, we will record high resolution video observations of seep communities and make discrete collections of sediments, rocks, megafauna (e.g., mussels), and water to improve our understanding of the biology and ecology of US Atlantic seeps and the processes that influence these unique environments.

The U.S. Atlantic margin offers an exciting setting for investigations related to the chronology of past methane seepage, because cold seeps are distributed over a large geographic area, a wide range of water depths, and diverse geological settings.

During the IMMeRSS Mid-Atlantic cruise, scientists will use acoustic instrumentation to detect methane plumes emitted from seafloor seep sites and to map the characteristics of the seafloor near seep sites.

The USGS Gas Hydrates Project is a multidisciplinary effort that is jointly supported by the Coastal and Marine Geology Program and the Energy Research Program at the USGS. Most personnel are based in Woods Hole, Massachusetts (Coastal and Marine) and in Denver (Energy). Additional personnel are located at the Santa Cruz Coastal and Marine Science Center, the Earthquake Program in Menlo Park, and the Minerals Program in Reston.
