Abstract:
Slope is derived from gridded (1 m cell size) multibeam
bathymetry, collected aboard the Survey Vessel Swamp Fox. Cell
values reflect the maximum rate of change (in degrees) in elevation
between neighboring cells derived with the ArcGIS Spatial Analyst
extension.
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
coral reef organisms.
Supplemental_Information:
Survey data were acquired by the United States Navy (USN) Fleet
Survey Team (FST) with Survey Vessel Swamp Fox. A Reson 8125
multibeam echosounder was mounted from an arm on the port
side of the vessel. The Klein 3000 Side Scan Sonar is operated
in the stern-towed configuration. Additional detailed
information on data acquisition, equipment configuration, and
corrections can be found in the Data Acquisition and Processing
Report (DAPR) that can be accessed at: www.soest.hawaii.edu/pibhmc
and is included in the ZIP file containing the bathymetry grids.
