U.S. Atlantic Margin Gas Hydrates and Methane Seeps Active
The U.S. Atlantic continental margin was one of the first locations where researchers recognized bottom simulating reflections, seismic features that are generally interpreted as marking the base of the gas hydrate stability zone in marine sediments. Geophysical cruises and ocean drilling in the 1990s provided insight into the Blake Ridge gas hydrate province. In the past decade, hundreds of seafloor methane seeps have been discovered on this margin between Cape Hatteras and Georges Bank. The USGS has conducted many cruises to image water column methane plumes, support geochemical and benthic ecology studies related to the methane seeps, and constrain the distribution of gas hydrates between Cape Hatteras and southern New England.

Surface methane concentrations along the mid-Atlantic bight driven by aerobic subsurface production rather than seafloor gas seeps
Relatively minor amounts of methane, a potent greenhouse gas, are currently emitted from the oceans to the atmosphere, but such methane emissions have been hypothesized to increase as oceans warm. Here, we investigate the source, distribution, and fate of methane released from the upper continental slope of the U.S. Mid-Atlantic Bight, where hundreds of gas seeps have been discovered between theAuthorsMihai Leonte, Carolyn D.

Spatial distributions and patchiness of dominant megafaunal invertebrates in deep-sea seep environments may indicate heterogeneities in the flux of reduced chemical compounds. At the Blake Ridge seep off South Carolina, USA, the invertebrate assemblage includes dense populations of live vesicomyid clams (an undescribed species) as well as extensive clam shell beds (i.e. dead clams).
