  Description: 
    Abstract: Slope is derived from gridded (5 m cell size) bathymetry from four sources:
      Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and
      NOAA Ship Hi'ialakai; multibeam bathymetry collected in Apra Harbor by the Naval Oceanographic
      Office and NOAA Office of Coast Survey; lidar collected by the Naval Oceanographic Office; and lidar
      collected by the Joint Airborne Lidar Bathymetry Technical Center of Expertise.
      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 US Territory of Guam.
    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 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.  These data are integrated with multibeam and lidar
      bathymetry data provided by the US Naval Oceanographic Office, NOAA Office of Coast Survey
      and the Joint Airborne Lidar Bathymetry Technical Center of Expertise.
      The metadata for these bathymetry data is documented in the product metadata,
      Guam_5m_Bathymetry_mb&lidar.txt.
      In two locations artifacts are visible in the data that result from the differing quality
      of the lidar versus multibeam data. In the northeast of Guam, north of Anao Point, it is possible
      to see the boundary between the lidar data (which shows as a rougher texture) and the deeper
      multibeam data (which shows as a smoother texture). A similar artifact is visible in a very
      small area along the northern edge of Pago Bay.
