Depth (Mean) Layer used to identify, delineate and classify moderate-depth benthic habitats around St. John, USVI
National Oceanic and Atmospheric Administration, Department of Commerce —
Mean depth was calculated from the bathymetry surface for each cell using the ArcGIS Spatial Analyst Focal Statistics "Mean" parameter. Mean depth represents the... -

Curvature Derivative Surface used to characterize the complexity of the seafloor around St. John, USVI
National Oceanic and Atmospheric Administration, Department of Commerce —
Curvature was calculated from the bathymetry surface for each raster cell using the ArcGIS 3D Analyst "Curvature" Tool. Curvature describes the rate of change of... -
