CRED Fagatele Bay National Marine Sanctuary Bathymetric Position Index Habitat Zones 2004

Description

Bathymetric Position Index (BPI) Zones derived from derivatives of Simrad EM-3000 multibeam bathymetry (3 m resolution). BPI zones are surficial characteristics of the seafloor based on a bathymetric position index value range at a broad scale and slope values. High-resolution multibeam bathymetry, derivatives of bathymetry (bathymetric position index, slope and rugosity), backscatter imagery and in situ visual survey data have been combined in a geographic information system (GIS). These data are supplemented by three-dimensional (3D) visualization. Within this study, methods were developed for benthic mapping and applied to three sites around American Samoa, a new classification scheme was developed for bathymetric position index (BPI) zones (depressions, slopes, flats, crests) and structures (finer features within zones) around the study sites, and visual survey information was associated with the results.
