- 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 Hiialaka'i, and R/V AHI, and it was created 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 French Frigate
Shoals, Hawaii, USA.
- 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 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. The metadata for the bathymetry is documented in
the product metadata, FFS_5m.asc.txt.

Bathymetric Position Index Structures were derived from the gridded
multibeam bathymetry (FFS_5m) 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 10 experimental
combinations, two scales (20 and 250) best identified fine scale
structures for French Frigate Shoals while
minimizing noise and optimizing possible reef structures (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).
