- Description:
-
- Abstract:
-
Gridded multibeam bathymetry is integrated with gridded lidar bathymetry.
Gridded (5 m cell size) multibeam bathymetry were collected aboard NOAA Ship
Hiialaka'i and R/V AHI and by the Naval Oceanographic Office and NOAA
Office of Coast Survey in Apra Harbor. Lidar bathymetry were collected by the Naval
Oceanographic Office and by the Joint Airborne Lidar Bathymetry Technical Center
of Expertise. This map shows the coverage of each of these sources of bathymetry data,
for the shelf environment of the US Territory of Guam Island.
- 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 by CRED in 2003 and 2007 aboard the Hi'ialakai, a 218'
United States National Oceanographic and Atmospheric Administration
(NOAA) research ship, and 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. The
metadata for these bathymetry is documented in the product metadata,
guam_5m.txt on ftp://ftp.soest.hawaii.edu/pibhmc/website/data/cnmi-guam/bathymetry
Multibeam data were also collected by the Naval Oceanographic Office and NOAA
Office of Coast Survey in 2008, in Apra Harbor. These data are also presented
in a 1-m resolution grid online, and metadata for these data are documented in the
product metadata apra_bty_1m.txt on
http://www.soest.hawaii.edu/pibhmc/pibhmc_cnmi_apra_bathy.htm.
Lidar data were provided by the Naval Oceanographic Office, and were obtained
using a SHOALS airborne system during January-March 2001. Additional lidar data were
collected by the Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX).
These data were collected using the CHARTS system between February 18 and May 20 2007.
These data are available on NGDC and more detailed metadata for these data can be found on https://coast.noaa.gov/digitalcoast//data/index.html
