Description:
Abstract:
Rugosity is derived from gridded (10 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hi'ialakai 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 and slope environment of Sarigan 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 depth (~20m to 800m) benthic habitats for 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, sarigan_10m.txt. (<http://www.soest.hawaii.edu/pibhmc/pibhmc_cnmi_bathy.htm>) References: Jenness, J. 2003.

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 6.084 with a mean of 1.138 and a standard deviation of 0.224.

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 (sarigan_10m) 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.
