Description:
Abstract:
BPI Zones are derived from 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 IKONOS satellite imagery. BPI Zones
was was created using the Benthic Terrain Modeler
(
https://coast.noaa.gov/digitalcoast/tools/btm.html). Cell values
represent one of 4 classes (crest, depression, flat, slope) in an
index of seafloor terrains. This data set is for the bank top, edge and lagoon environments of Kure Atoll, Hawaii, USA.
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 (~20 m to 150 m)
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 ft survey launch owned and
operated by the NOAA Pacific Islands Fisheries Science Center in
Honolulu, HI and derived from IKONOS satellite
imagery. The metadata for the bathymetry is documented in
the product metadata: kur_5m.asc.
