Summary

These data are a qualitatively derived interpretive polygon shapefile defining surficial sediment type and distribution, and geomorphology, for nearly 1,400 square kilometers of sea floor on the inner-continental shelf from Fenwick Island, Maryland to Fisherman’s Island, Virginia, USA. These data are classified according to Barnhardt and others (1998) bottom-type classification system, which was modified to highlight changes in secondary sediment-types such as mud and gravel across this primarily sandy shelf. Most of the geophysical and sample data used to create this interpretive layer were collected as part of the Linking Coastal Processes and Vulnerability: Assateague Island Regional Study project (GS2-2C), supported by the U.S. [...]

Purpose

These sea-floor data were created from geophysical and sample data collected along the Delmarva Peninsula from Fenwick Island, Maryland to Fisherman's Island, Virginia. These data are an interpretation of the seafloor sediment type, distribution, and geomorphology, and are classified according to a modified Barnhardt bottom-type classification system in order to capture meaningful changes in seafloor texture along the inner continental shelf of this region. Seafloor interpretations are important data layers for marine resource managers charged with protecting fish habitat, delineating marine boundaries, and assessing environmental change due to natural or human impacts.
