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 Hiialaka'i, and R/V AHI, and it 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 the shelf and slope environments of French Frigate Shoals, Hawaii, 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 multibeam data were collected aboard the Hi'ialakai,a 218' United States National Oceanographic and Atmospheric Administration (NOAA) research ship, and aboard the R/V AHI (Acoustic Habitat Investigator), a 25' survey launch owned and operated by the NOAA Pacific Islands Fisheries Science Center in Honolulu, HI. The metadata for the bathymetry is documented in the product metadata, FFS_5m.asc.txt.

Process_Description:
Bathymetric Position Index Structures were derived from the gridded multibeam bathymetry (FFS_5m) using the Benthic Terrain Modeler (BTM). The BTM (written for ArcGIS 8.x or 9.x) may be downloaded from <http://dusk2.geo.orst.edu/djl/samoa/tools.html>. BPI Structures are derived from two scales of a focal mean analysis on bathymetry and slope. After testing 10 experimental combinations, two scales (20 and 250) best identified fine scale structures for French Frigate Shoals while minimizing noise and optimizing possible reef structures (also after Lundblad et al. 2006; see Supplemental_Information). Three ranges of slope define flats, slopes, and near vertical: x < 5; 5 < x < 70; x > 70. Depth alone, in this case, is added only to separate flat structures into shelf (<30 m) and broad flat (>30 m) environments (depths based on SCUBA limits).
