The data were collected to provide information on the 25, 50, and 100 fm contours in the NWHI, which are important for establishing management boundaries for the NWHI Coral Reef Ecosystem Reserve. The data are being used to provide bathymetric and backscatter data for previously unmapped areas. The data support ecosystem management requirements for benthic habitat mapping and location of Essential Fish Habitat. The data are also used to study the geologic features of the area.
