U.S. Atlantic Margin Seeps
Schematic showing the general setting of seeps on the US Atlantic margin and related processes, such as gas hydrate degradation, groundwater seepage, leakage through fractured rocks, or emissions from the seafloor overlying salt diapirs. Pockmarks shown in white, and the nominal updip limit of gas hydrate stability is represented by the dashed black line. Analyses indicate that present-day seepage on this margin does not coincide with pockmarks. After the Nature Geoscience schematic.
