Description:
Abstract:
BPI Structures are derived from two scales of a focal mean analysis on bathymetry and slope. The grid is based on gridded (5 m cell size) multibeam bathymetry, collected aboard NOAA Ship Oscar Elton Sette. BPI Structures was created using the Benthic Terrain Modeler (<http://www.csc.noaa.gov/digitalcoast/tools/btm/>). The Cell values represent one of 12 classes in an index of seafloor terrains. This data set is for Galvez Bank, South Galvez Bank, and 11-Mile Reef, Territory of Guam, USA.
Purpose:
The data were derived in support of Coral Reef Conservation Program goals. Goal 1 is to map all U.S. Coral Reef Ecosystems. This data set specifically addresses Objective 1 and 4: to develop high-resolution benthic maps and to characterize priority deep water reefs and associated habitats. This derivative of bathymetry provides a GIS layer that may be used for benthic and essential fish habitat characterization, and for the study of geologic features. By combining the dataset with bathymetry, backscatter, other derivatives, and in situ data, they collectively compose benthic habitat maps which are designed to be used to understand and predict moderate depth (~20m to ~150m) benthic habitats for different organisms that inhabit coral reef ecosystems.
Supplemental_Information:
Gridded bathymetry data were collected aboard the NOAA Ship Oscar Elton Sette, a 224' (68 m) United States National Oceanographic and Atmospheric Administration research ship. The NOAA Ship Sette's survey sensors included a 240-kHz pole-mounted Reson 8101ER sonar, which provides bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position,velocity, attitude and heading, and a Seabird SBE19 CTD used to measure sound velocity profiles. The metadata for the bathymetry is documented in this product metadata: <ftp://ftp.soest.hawaii.edu/pibhmc/website/data/cnmi-guam/bathymetry/3Banks_Guam_5m.txt>

Specific equipment configurations are documented in metadata from cruise SE1002. These metadata can be accessed at: <http://www.soest.hawaii.edu/pibhmc/pibhmc_cruise-catalog.htm>

Process_Description:
Bathymetric Position Index Structures were derived from the gridded multibeam bathymetry for Galvez Bank (gal5m), South Galvez Bank (sgal5m) and Eleven-Mile Reef (ele5m) using the Benthic Terrain Modeler (BTM) Version 3.0 (beta) for ArcGIS10.1 Desktop (<http://www.csc.noaa.gov/digitalcoast/tools/btm/>). BPI Structures are derived from two scales (broad and fine-scale) of a focal mean analysis on bathymetry and slope. After testing different experimental combinations, the following broad and fine scales were chosen as best identifying fine-scale structures for Galvez Banks (30 and 150), 11 Mile Reef (50 and 150) and South Galvez 30 and 150). Three ranges of slope define flat, slope, and near vertical: x < 5; 5 < x < 70; x > 70. There may be edge effects at the outer extent of the data.
