      Title: Rugosity 60 m grid derived from gridded bathymetry of Guam Island,
        Mariana Islands, USA
      Geospatial_Data_Presentation_Form: raster digital data

  Description: 
    Abstract: Rugosity is derived from gridded (60 m cell size)
      multibeam bathymetry, collected aboard NOAA Ship Hiialaka'i and
      R/V AHI, using the Benthic Terrain Modeler with rugosity methods by
      Jeff Jenness (2003). Cell values reflect the surface area to planimetric
      area ratio for the area contained within that cell's neighborhood.
      They provide indices of topographic roughness & convolutedness.
      This data set is for the shelf environment 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 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 to deep depth (~10m to 3500m) 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.  The
      metadata for the bathymetry is documented in the product metadata,
      guam_60m.txt.  (http://www.soest.hawaii.edu/pibhmc/pibhmc_cnmi_bathy.htm)

      CNMI and Guam rugosity maps are all symbolized with the same
      stretched color ramp (1.5 standard deviations) in order to provide a
      standard for qualitative comparisons between islands. Each island has
      a unique maximum value for rugosity causing the distribution of values
      across the color ramp to vary slightly. It is recommended that
      the actual data set be used for integrated analysis in order to make
      quantitative observations. The values for this data set range from
      1.000 to 1.904 with a mean of 1.025 and a standard deviation of 0.043.
      
      The terrestrial elevation data shown in the map for this data set are
      SRTM Finished 3 arc sec Shaded Relief. They were collected during
      NASA's Shuttle Radar Topograph Mission (SRTM). For more information
      on the mission, go to:
      http://www2.jpl.nasa.gov/srtm/faq.html#data. The data are available
      from the United States Geological Survey (USGS) as reformatted
      elevation data that are consistent with other Digital Elevation Models.

      Process_Description: Rugosity was derived from the gridded multibeam bathymetry
        (guam_60m) using the Benthic Terrain Modeler (BTM). The BTM may
        be downloaded from http://www.csc.noaa.gov/products/btm/. The BTM,
        written for ArcGIS 8.x or 9.x, includes a component for deriving
        rugosity using methods by Jeff Jenness as he wrote for ArcView 3.x.
