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 <http://www.csc.noaa.gov/digitalcoast/data/index.html>
