Description
BPI Structures are derived from a focal mean analysis on bathymetry and slope. The bathymetry grid (5 m cell size) is derived from bathymetry from three sources: Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and NOAA Ship Hi'ialakai; Multibeam bathymetry collected aboard the US Naval Ship Sumner, and lidar, both collected by Naval Oceanographic Office; and bathymetry derived from multispectral IKONOS satellite imagery. BPI Structures was created using the Benthic Terrain Modeler (http://www.csc.noaa.gov/products/btm/). Cell values represent one of 13 classes in an index of seafloor terrains.This data set is for Tinian and Aguijan Islands, and Tatsumi Bank, Commonwealth of the Northern Marianas (CNMI).
