- Abstract:
-
BPI Structures are derived from two scales of a focal mean
analysis on bathymetry; slope; and depth. The grid is based on
gridded (5 m cell size) multibeam bathymetry, collected aboard NOAA
Ship Hiialaka'i and R/V AHI, and it was creating using the Benthic
Terrain Modeler (http://www.csc.noaa.gov/products/btm/). Cell values
represent one of 13 classes in an index of seafloor terrains. This
data set is for the shelf and slope environments of Tutuila Island,
American Samoa, South Pacific.
- 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 foot United States National Oceanographic and Atmospheric
Administration (NOAA) research ship, and aboard the R/V AHI
(Acoustic Habitat Investigator), a 25 foot survey launch owned and
operated by the NOAA Pacific Islands Fisheries Science Center in
Honolulu, HI. The metadata for the bathymetry is documented in
the product metadata, Tutuila_5m.asc.txt.

Bathymetric Position Index Structures were derived from the gridded
multibeam bathymetry (Tutuila_5m) using the Benthic Terrain Modeler
(BTM). The BTM may be downloaded from
http://www.csc.noaa.gov/products/btm/. The BTM was written for
ArcGIS 8.x or 9.x.
BPI Structures are derived from two scales of a focal mean analysis
on bathymetry; slope; and depth. After testing 10 experimental
combinations, the two scales of bpi (20 & 250) were chosen based
on the diameter of reef structures seen in the bathymetry (also
after Lundblad et al. 2006; see Supplemental_Information). Three
ranges of slope define flats, slopes, and near vertical: x < 5;
5 < x < 70; x > 70. Depth alone, in this case, is added only to
separate flat structures into shelf (<30 m) and broad flat (>30 m)
environments (depths based on SCUBA limits).
