Defne, Z., and Ganju, N.K., 2018, Elevation of marsh units in Plum Island Estuary and Parker River salt marsh complex, Massachusetts: U.S. Geological Survey data release, https://doi.org/10.5066/P9R229RI.

Summary

This data release provides elevation distribution in the Plum Island Estuary and Parker River (PIEPR) salt marsh complex. Elevation distribution was calculated in terms of mean elevation of conceptual marsh units defined by Defne and Ganju (2018). The elevation data was based on the 1-meter gridded Digital Elevation Model and supplemented by 1-meter resampled 1/9 arc-second resolution National Elevation Data, where data gaps exist. Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands, including the Plum Island Estuary and Parker River salt marsh complex, with the intent of providing [...]

Purpose

The purpose of this shapefile is to calculate mean elevation for each marsh unit and its vegetated component. Analysis of marsh elevation is planned to be a part of a comprehensive assessment to identify the factors and their weights in determining the vulnerability and resiliency of salt marshes.
