Description:
Abstract:
Rugosity 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. Rugosity is derived 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 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 (<http://www.soest.hawaii.edu/pibhmc/pibhmc_cnmi_gua_bathy.htm>). 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. 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. References: Jenness, J. 2003.

Process_Description:
Rugosity was derived from the gridded multibeam bathymetry (gua_mb_ld) using the Benthic Terrain Modeler (BTM). The BTM may be downloaded from <http://www.csc.noaa.gov/digitalcoast/tools/btm/index.html>. 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.
