Slope grid derived from gridded bathymetry of Pearl and Hermes Atoll, Hawaii, USA

- Description:

- Abstract:
-
Slope is derived from gridded (5 m cell size) multibeam
bathymetry, collected aboard NOAA Ship Hiialaka'i and R/V AHI, and
IKONOS derived depth values. 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 the bank top
and lagoon environments of Pearl and Hermes 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
coral reef organisms.
- Supplemental_Information:
-
Gridded multibeam data were collected aboard the Hiialakai, 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, PH_5m.asc.txt.
