Description:

Abstract:

BPI Zones are derived from a focal mean analysis on bathymetry and slope. The bathymetry grid (5 m cell size) is derived from bathymetry from two sources: Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and NOAA Ship Hi'ialakai; multibeam bathymetry collected aboard the US Naval Ship Sumner by the Naval Oceanographic Office, and lidar, also collected by the Naval Oceanographic Office. BPI Zones was created using the Benthic Terrain Modeler (http://www.csc.noaa.gov/products/btm/). Cell values represent one of four classes in an index of seafloor terrain; flats, depressions, crests and slopes. This data set is for Saipan Islands, Commonwealth of the Northern Marianas (CNMI).

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 - 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. These data are integrated with multibeam and lidar bathymetry data provided by the US Naval Oceanographic Office. For the purposes of creating a bathymetry grid (sai_mb_li_db) these bathymetry data were also combined with bathymetry derived from multispectral IKONOS satellite data. The metadata for these bathymetry is documented in the product metadata, Sai_MB_Li_DB_metadata.txt. However, for the purpose of deriving BPI, a version of this data was used that did not include the IKONOS-derived bathymetry, as these data were found to introduce artifacts into the BPI Zones product.

Process_Description:

Bathymetric Position Index Zones were derived from the gridded bathymetry (sai_mb_li_db without IKONOS-derived bathymetry, as described above) 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 Zones are derived from a focal mean analysis on bathymetry and slope. After testing three different scalefactors, a scalefactor of 150 was chosen as best identifying broad scale features, while minimizing artifacts (also after Lundblad et al. 2006; see Supplemental_Information). Two ranges of slope define flat and slope, x < 5 and x > 5. There may be edge effects at the outer extent of the data.
