Summary

As part of the Hurricane Sandy Science Plan, the U.S. Geological Survey is expanding National Assessment of Coastal Change Hazards and forecast products to coastal wetlands. The intent is to provide federal, state, and local managers with tools to estimate the vulnerability of coastal wetlands to various factors and to evaluate their ecosystem service potential. For this purpose, the response and resilience of coastal wetlands to physical factors need to be assessed in terms of the ensuing change to their vulnerability and ecosystem services. Edwin B. Forsythe National Wildlife Refuge (EBFNWR), New Jersey, was selected as a pilot study area. As part of this data synthesis effort, hydrodynamic and sediment transport modeling of Barnegat [...]

Purpose

This polygon dataset facilitates quantifying the changes in salinity exposure of vegetation in the EBFNWR salt marsh complex by summarizing the results over the previously determined conceptual salt marsh unit polygons (Defne and Ganju, 2016b). Analysis of episodic change in salinity exposure is part of a comprehensive assessment to identify the factors and their weights in determining the vulnerability and resiliency of salt marshes. Salinity exposure was defined as the depth-averaged salinity times the duration of exposure. Change in salinity exposure has been estimated based on the hydrodynamic modeling of Barnegat Bay - Little Egg Harbor (BBLEH) estuary during Hurricane Sandy period from 10/27/2012 to 11/04/2012 (Defne and Ganju, 2016a).
