Polygon boundary describing the source surveys used to build the Bathymetric Terrain Model of the U.S. Atlantic Margin of 100-meter resolution compiled by the U.S. Geological Survey (Esri Shapefile, Geographic WGS 84 Coordinate System)

Bathymetric Terrain Models (BTMs) of seafloor morphology are an important component of marine geological investigations. Advances in acquisition and processing technologies of bathymetry data have facilitated the creation of high-resolution bathymetric surfaces that approach the resolution of those available for onshore investigations. These BTMs provide a detailed representation of the Earth's subaqueous surface and when combined with other geophysical and geologic datasets, allow for interpretation of modern and ancient geologic processes.
