    • Bathymetric Position Index (BPI) Zones 10 m grid derived from gridded bathymetry of Agrihan Island, Commonwealth of the Northern Mariana Islands, USA.

    Metadata Updated: March 22, 2025

    BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (10 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hi'ialakai and R/V AHI, and it was created using the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast/tools/btm.html). Cell values represent one of 4 classes (crest, depression, flat, slope) in an index of seafloor terrains. This data set is for the shelf and slope environments of Agrihan Island.
