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).
