Abstract:
Gridded multibeam bathymetry is integrated with bathymetry
derived from multpectral World View-2 satellite data. Gridded (5 m cell
size) multibeam bathymetry collected aboard NOAA Ship Hiialaka'i and
R/V AHI. Multibeam data were also collected aboard the NOAA Ship Oscar
Elton Sette in 2010, a 224? (68 m) United States National Oceanographic
and Atmospheric Administration research ship. Bathymetry values shallower
than ~20 m were derived by gauging the reletive attenuation of coastal,
blue, green and yellow spectral radiance as a function of depth. A multiple
linear regression analysis of coastal,blue, green and yellow band spectral
values against depth determined the variables of y-intercept, coastal,blue,
green and yellow slope values. Variables then used in multivariate slope
intercept formula to derive depth. Digital image processing to derive depths
conducted with the ENVI 4.8 software program while data editing and integration
was performed using ArcGIS 10. This data set is for the shelf environment of
Rota Island, Mariana.
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 integration of derived
bathymetry with multibeam sonar data provides a GIS layer with
expanded spatial coverage that may be used for benthic and essential
fish habitat characterization, and for the study of geologic features.
By combining the dataset with other bathymetry, backscatter, derivatives,
and in situ data, they collectively compose benthic habitat maps
designed to be used to understand and predict shallow depth (0m to 150m)
benthic habitats for 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, aboard the R/V AHI (Acoustic Habitat
Investigator), a 25? survey launch owned, and aboard the NOAA Ship
Oscar Elton Sette in 2010, a 224? (68 m) United States National Oceanographic
and Atmospheric Administration research ship.
