Description:
Abstract:
Rugosity is derived from gridded (5 m cell size) multibeam
bathymetry, aboard NOAA Ship Oscar Elton Sette.
Cell values reflect the (surface area) / (planimetric area)
ratio for the area contained within that cell's boundaries. They
provide indices of topographic roughness & convolutedness. The bathymetry grid includes multibeam bathymetry from the
Reson 8101 multibeam sonar aboar the NOAA Ship Oscar E. Sette collected as of
May 2010 by the NOAA Coral Reef Ecosystem Division in depths between 10 and 300
meters. These data complement multibeam data collected by the U.S. Naval Oceanographic
Office at FDM during several test cruises, which are available from NOAA's National
Geophysical Data Center.
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:
Multibeam data were collected aboard the NOAA Ship Oscar Elton Sette, a 224’ (68 m) United States
National Oceanographic and Atmospheric Administration research ship. The NOAA Ship
Sette's survey sensors included a 240-kHz pole-mounted Reson 8101ER sonar, which provides
bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position,velocity, attitude and
heading, and a Seabird SBE19 CTD used to measure sound velocity profiles.
Specific equipment configurations are documented in metadata from cruise
SE1002. These metadata can be accessed at:
