Bathymetric Position Index (BPI) Zones derived from gridded bathymetry of Farallon de Medinilla (FDM), Commonwealth of the Northern Mariana (CNMI), USA.
Description
BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is derived from gridded (5 m cell size) bathymetry and was created using the Benthic Terrain Modeler 3.0 (Beta 3). The bathymetry grid includes multibeam bathymetry from the Reson 8101 multibeam sonar aboar the NOAA Ship Oscar E. Sette collected as of May 2010 by the NOAA Coral Reef Ecosystem Division in depths between 10 and 300 meters. These data complement multibeam data collected by the U.S. Naval Oceanographic Office at FDM during several test cruises, which are available from NOAA's National Geophysical Data Center.
