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. Purpose: BPI Zones were derived as a baseline, or framework, for spatial analysis during future habitat studies around American Samoa.

Lineage: Process_Step: Process_Description: This study uses the extensive multibeam bathymetry coverage around American Samoa to analyze and classify Bathymetric Position Index (BPI) zones, structures and rugosity for depths that can not be efficiently reached by other surveying methods. The methods developed here and applied to American Samoa sites are the first to successfully create a benthic classification for multibeam bathymetry beyond 30 meters depth that extends existing shallow water benthic classifications (The Development and Application of Benthic Classifications for Coral Reef Ecosystems Below 30M Depth using Multibeam Bathynmetry: Tutuila, American Samoa, 2004, Appendix A). Spatial analysis was used to derive slope and multiple scales of bathymetric position from the original bathymetry. The resulting derivative grids were combined with a new algorithm to develop final products: BPI zones, structures and rugosity classification maps for each study site. The maps make use of a new classification scheme that may be extended to other coral reef systems. The classification methods identify four BPI zones: crests, depressions, flats, and slopes. if (nfb02_tpi250s >= 100) fb_zns = 1 else if (nfb02_tpi250s <= -100) fb_zns = 2 else if (nfb02_tpi250s > -100 and nfb02_tpi250s < 100 and nfb02_slp <= 5) fb_zns = 3 else if (nfb02_tpi250s > -100 and nfb02_tpi250s < 100 and nfb02_slp > 5) fb_zns = 4 endif For additional information see ftp://ftp.soest.hawaii.edu/pibhmc/web/docs/Lundblad_Thesis.pdf Source Used: http://dusk.geo.orst.edu/djl/samoa Process_Date: 20030624 Process_Contact: Contact_Information: Contact_Organization_Primary: Contact_Organization: Pacific Islands Benthic Habitat Mapping Center (PIBHMC), Coral Reef Ecosystem Division (CRED), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA) Contact_Address: Address_Type: mailing and physical address Address: NOAA IRC Address: NMFS/PIFSC/CRED Address: 1845 WASP Blvd., Building 176 City: Honolulu State_or_Province: HI Postal_Code: 96818 Contact_Voice_Telephone: 808 725-5360 Contact_Facsimile_Telephone: 808 725-5429 Contact_Electronic_Mail_Address: nmfs.pic.credinfo@noaa.gov Spatial_Data_Organization_Information: Direct_Spatial_Reference_Method: Raster Raster_Object_Information: Raster_Object_Type: Grid Cell Row_Count: 624 Column_Count: 620 Vertical_Count: 1 Spatial_Reference_Information: Horizontal_Coordinate_System_Definition: Planar: Grid_Coordinate_System: Grid_Coordinate_System_Name: Universal Transverse Mercator Universal_Transverse_Mercator: UTM_Zone_Number: -2 Transverse_Mercator: Scale_Factor_at_Central_Meridian: 0.999600 Longitude_of_Central_Meridian: -171.000000 Latitude_of_Projection_Origin: 0.000000 False_Easting: 500000.000000 False_Northing: 10000000.000000 Planar_Coordinate_Information: Planar_Coordinate_Encoding_Method: row and column Coordinate_Representation: Abscissa_Resolution: 2.965509 Ordinate_Resolution: 2.965509 Planar_Distance_Units: meters Geodetic_Model: Horizontal_Datum_Name: D_WGS_1984 Ellipsoid_Name: WGS_1984 Semi-major_Axis: 6378137.000000 Denominator_of_Flattening_Ratio: 298.257224 Distribution_Information: Distributor: Contact_Information: Contact_Organization_Primary: Contact_Organization: Pacific Islands Benthic Habitat Mapping Center (PIBHMC), Coral Reef Ecosystem Division (CRED), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA) Contact_Address: Address_Type: mailing and physical address Address: NOAA IRC Address: NMFS/PIFSC/CRED Address: 1845 WASP Blvd., Building 176 City: Honolulu State_or_Province: HI Postal_Code: 96818 Contact_Voice_Telephone: 808 725-5360 Contact_Facsimile_Telephone: 808 725-5429 Contact_Electronic_Mail_Address: nmfs.pic.credinfo@noaa.gov Resource_Description: Downloadable Data Distribution_Liability: NOT for navigational purposes NOAA makes no warranty regarding these data,expressed or implied, nor does the fact of distribution constitute such a warranty.
