Description

BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (5 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hi'ialakai and R/V AHI, and it was creating using the Benthic Terrain Modeler (http://www.csc.noaa.gov/products/btm/). Cell values represent one of 4 classes in an index of seafloor terrains. This data set is for the shelf and slope environments of Tutuila Island, American Samoa, South Pacific.
