USGS hydrologist Kaitlyn Colella and a Shinnecock Nation member work together gathering oyster and bed sediment samples.  Contaminants released and or mobilized as a result of Hurricane Sandy may be retained in bed sediments in aquatic environments and may be accumulating in exposed organisms, especially at low trophic levels (for example, oysters).

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.
