- 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 R/V AHI
merged with seafloor depths derived from multispectral
IKONOS satellite imagery. BPI Structures was created using the Benthic
Terrain Modeler (http://www.csc.noaa.gov/products/btm/). Cell values
represent one of 12 classes in an index of seafloor terrains. This data set
is for Rose Atoll, American Samoa.
- 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 bathymetry data were collected 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 and derived from multispectral IKONOS satellite
imagery. The metadata for the bathymetry is documented in
the product metadata, rose_5m_dbmb.asc.txt

Bathymetric Position Index Structures were derived from the gridded
multibeam and IKONOS merged bathymetry (rose_5m_dbmb) 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 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.
