Description:
Abstract:
Slope is derived from gridded (5 m cell size) bathymetry, from three sources:
Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and
NOAA Ship Hi'ialakai; Multibeam bathymetry collected aboard the US Naval Ship Sumner, and
lidar, both collected by Naval Oceanographic Office; and bathymetry derived from multispectral
IKONOS satellite imagery.
Cell values reflect the maximum rate of change (in degrees) in
elevation between neighboring cells derived with the ArcGIS
Spatial Analyst extension. This data set is for Tinian and Aguijan Islands, and Tatsumi Bank,
Commonwealth of the Northern Marianas (CNMI).
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 - 150m) benthic habitats for different
organisms that inhabit coral reef ecosystems.
Supplemental_Information:
Gridded multibeam data were collected aboard the R/V AHI
(Acoustic Habitat Investigator), a 25' survey launch owned and
operated by the NOAA Pacific Islands Fisheries Science Center in
Honolulu, HI. These data are integrated with bathymetry derived
from multispectral IKONOS satellite data and multibeam and lidar
bathymetry data provided by the US Naval Oceanographic Office.
The metadata for the bathymetry is documented in the product metadata,
TinMBLiDBmos_metadata.txt.
