“Learning from the Impacts of Superstorm Sandy: Paleotempestology on Long Island.”

E. Christa Farmer and J. Bret Bennington


Analysis of the sedimentology and stratigraphy of Superstorm Sandy washover lobes reveals a grain size profile that is consistent with washout of the dune line as the major source of washover sand. Superstorm Sandy washover deposits are compared to overwash-generated layers in core matched to 20th Century storms using historical aerial photographs. The close similarity in sedimentological characteristics demonstrates that previous washover deposits in this area preserved in the subsurface have very similar characteristics to Sandy overwash, which can be used to distinguish overwash from other types of coarse-grained deposits in the marsh. Trace metal (Cu, Zn, and Pb) concentration profiles in the sediment cores collected from a saltwater marsh on a barrier beach island near Hampton Bays, NY are consistent with values seen in other Atlantic coast saltwater marshes. Peak Pb values in the middle of the profiles are consistent with a higher anthropogenic signal in the middle of the last century, and provide insight into the timing of storm deposits.
