Description:
Abstract:
Rugosity is derived from gridded (5 m cell size)
multibeam bathymetry, collected aboard NOAA Ship Hiialaka'i
and R/V AHI, and IKONOS derived depths using the Benthic
Terrain Modeler with rugosity methods by Jeff Jenness (2003).
Cell values reflect the surface area and
(surface area) / (planimetric area) ratio for the area
contained within that cell's boundaries. They provide indices of
topographic roughness & convolutedness. This data set is for
the bank top and lagoon environments of Kure Atoll, Hawaii, USA.
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 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 ft United States National Oceanographic and Atmospheric
Administration (NOAA) research ship, and 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. IKONOS estimated depths were produced using rule-based,
semi-automated image analysis of high-resolution satellite imagery.
The metadata for the bathymetry is documented in the product metadata,
Kure_5m.asc.txt.
