The grid is based on gridded (5 m cell size) multibeam bathymetry, collected aboard R/V AHI merged with seafloor depths derived from multispectral IKONOS satellite imagery. BPI Structures was created using the Benthic Terrain Modeler (https://coast.noaa.gov/digitalcoast/tools/btm.html). Cell values represent one of 12 classes in an index of seafloor terrains. This data set is for Rose Atoll, American Samoa. 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.

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 9 experimental combinations, two scales (30 and 200) best identified fine scale structures for Rose Atoll while minimizing noise and optimizing possible reef structures (also after Lundblad et al. 2006; see Supplemental_Information). 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. Further artifacts are visible on the reef crest; these may be due to noise in the original IKONOS image, or discrepancies between the merged IKONOS and multibeam bathymetry. 2010-06-01T00:00:00 otherRestrictions Metadata Access Constraints: None otherRestrictions Metadata Use Constraints: None annually This metadata was automatically generated from the FGDC Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
