Description:

Abstract:

Rugosity is derived from gridded (5 m cell size) multibeam bathymetry, aboard NOAA Ship Oscar Elton Sette. Cell values reflect the (surface area) / (planimetric area) ratio for the area contained within that cell's boundaries. They provide indices of topographic roughness & convolutedness. This data set is for Thirty-Five Fathom Bank, and Thirty-Seven Fathom Bank, Commonwealth of the Northern Marianas.

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 to 150m) benthic habitats for different organisms that inhabit coral reef ecosystems.

Supplemental_Information:

Gridded bathymetry data were collected aboard the NOAA Ship Oscar Elton Sette, a 224’ (68 m) United States National Oceanographic and Atmospheric Administration research ship. The NOAA Ship Sette's survey sensors included a 240-kHz pole-mounted Reson 8101ER sonar, which provides bathymetry and imagery data, a TSS/Applanix POS/MV Model 320, which measures position,velocity, attitude and heading, and a Seabird SBE19 CTD used to measure sound velocity profiles. The metadata for the bathymetry is documented in this product metadata: ftp://ftp.soest.hawaii.edu/pibhmc/website/data/cnmi-guam/bathymetry/35fth_37fth_Bank_5m_bathy.txt Specific equipment configurations are documented in metadata from cruise SE1002.

Process_Description:

Rugosity was derived using the tool Surface Area and Ratio (Surface Ratio), available from DEM Surface Tools v 2.1.305 which are produced by Jenness Enterprises and available online at: http://www.jennessent.com/arcgis/surface_area.htm Rugosity was derived from the gridded (5m) bathymetry of Thirty-Five Fathom Bank and Thirty-Seven Fathom Bank. Prior to calculating rugosity, both bathymetry grids were clipped to 200 m. Input surfaces: tff_5m_200 and tsf_5m_200;
