Peat auger core collected from the back-barrier marsh of Assateague Is

Detailed Description

A peat auger core collected from the back-barrier marsh of Assateague Island, Maryland. An inorganic-rich layer found at the top of the core was delivered to the marsh via Hurricane Sandy. Visual contrast in sediment down-core reveal similar layers as that observed at the top of the core (i.e., Hurricane Sandy layer). Detailed grain size analysis, measurement of basic textural parameters (bulk density and organic matter), and chronology helped refine the origin of these event layers and how they contributed to marsh accretion. In addition, the dated layers provide evidence of overwash observed in historical remote sensing data.
