CRED Bathymetric Position Index (BPI) Structures grid derived from gridded bathymetry of Tutuila Island, American Samoa, South Pacific
Description
BPI Structures are derived from two scales of a focal mean analysis on bathymetry; slope; and depth. The grid is based on gridded (5 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hiialaka'i and R/V AHI, and it was creating using the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast/tools/btm.html). Cell values represent one of 13 classes in an index of seafloor terrains. This data set is for the shelf and slope environments of Tutuila Island, American Samoa, South Pacific.
