- 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.

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.
