Geospatial characterization of South Atlantic Bight salt marshes

This data release provides conceptual marsh units for salt marshes in the South Atlantic Bight of the southeastern United States. Marsh plains are subdivided into smaller units using a digital elevation model, capturing the spatial variability of physical factors that influence wetland condition. The U.S. Geological Survey is expanding its national assessment of coastal change hazards and forecast products to include coastal wetlands with the goal of providing managers with tools to estimate the vulnerability and ecosystem service potential of these wetlands. Understanding how these wetlands adapt to change is key to this effort.
