Methane Seeps along Offshore New England
Seafloor image at a deepwater (~1400 m water depth) seep site on the New England margin. Seafloor conditions here are well inside the pressure-temperature stability field for methane hydrate. Gas being emitted below the rock overhang has formed gas hydrate (the white ice-like material). Distinct bubbles are visible in the foreground. The red laser scale is 10 cm.
