Summary

This data set contains rate of shoreline change statistics for New York State coastal wetlands. Analysis was performed in ArcMap 10.5.1 using historical vector shoreline data from the National Oceanic and Atmospheric Administration (NOAA). Rate of change statistics were calculated using the Digital Shoreline Analysis System (DSAS), created by U.S. Geological Survey, version 5.0. End-point rates, calculated by dividing the distance of shoreline movement by the time elapsed between the oldest and the most recent shoreline, were generated for wetlands where fewer than three historic shorelines were available. Linear regression rates, presented here, were determined by fitting a least-squares regression line to all shoreline points [...]

Purpose

This data set is part of a cooperative agreement between USGS and New York State Department of Environmental Conservation to assess coastal wetland vulnerability within the state. Monitoring shoreline change enables quantification of land loss or gain over time, determined by the balance between erosion and accretion along coasts. Metrics such as this are valuable to management decision makers in evaluating long-term wetland viability. In the case of salt marshes, erosion along the water boundary causes a loss of ecosystem services, such as habitat provision, carbon storage, and wave attenuation.
