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. The grid is derived from gridded (5 m cell size) bathymetry and was created using the Benthic Terrain Modeler 3.0 (Beta 3). The Cell values represent one of 13 classes in an index of seafloor terrains. The bathymetry grid includes multibeam bathymetry from the Reson 8101 multibeam sonar aboar the NOAA Ship Oscar E. Sette collected as of May 2010 by the NOAA Coral Reef Ecosystem Division in depths between 10 and 300 meters. These data complement multibeam data collected by the U.S. Naval Oceanographic Office at FDM during several test cruises, which are available from NOAA's National Geophysical Data Center.

Purpose:

The data were derived in support of NOAA 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:

Multibeam 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.

Specific equipment configurations are documented in metadata from cruise SE1002. These metadata can be accessed at: http://www.soest.hawaii.edu/pibhmc/cms/cruise-catalog/ Metadata for the bathymetry grid can be found here: ftp://ftp.soest.hawaii.edu/pibhmc/website/data/cnmi-guam/bathymetry/FDM_5m.txt

Process_Description:

Bathymetric Position Index Structures were derived from the gridded multibeam bathymetry for Faraloon de Medinilla using the Benthic Terrain Modeler (BTM) Version 3.0 (beta) for ArcGIS10.1 Desktop (https://coast.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, scalefactors of 200 and 25 were used for broad and fine scale grids. 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.
