ArcGIS Benthic Terrain Modeler (BTM), v. 3.0, Environmental Systems Research Institute, NOAA Coastal Services Center, Massachusetts Office of Coastal Zone Management. Available online at [https://esriurl.com/5754]. Rugosity is derived for islands and banks across the U.S. Pacific Islands Region primarily from gridded multibeam bathymetry collected aboard NOAA Ships Hi'ialakai and Oscar Elton Sette, and aboard R/V AHI (Acoustic Habitat Investigator) from 2003 to 2012 by the PIFSC Ecosystem Sciences Division (ESD). Other sources of available data used to derive rugosity for a few locations include estimated depths derived from IKONOS satellite imagery from 2000 to 2002, LIDAR data from 2001 and 2007, and multibeam bathymetry collected in 2001 and 2002. Rugosity is derived using the Benthic Terrain Modeler with rugosity methods by Jeff Jenness (2004). 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. The rugosity grids generated for each location are available via the Pacific Islands Benthic Habitat Mapping Center (PIBHMC) website. The data, maps, layer files, and detailed documentation (more specific than this pacific-wide record) about the data sources are included in the zip file for each location. Prepared by the PIFSC Ecosystem Sciences Division (ESD) and funded by the NOAA Coral Reef Conservation Program (CRCP), the data were derived in support of CRCP goals to map all U.S. coral reef ecosystems by developing high-resolution benthic maps to characterize priority 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. These data can be combined with bathymetry, backscatter, derivatives, and other datasets to compose benthic habitat maps that can be used to understand and predict benthic habitats for different organisms that inhabit coral reef ecosystems. These maps were made possible with funding from the CRCP, and additional support was received from the NOAA Habitat Blueprint for the West Hawaii Focus Area.

This multibeam data may be synthesized with other data including LiDAR bathymetry and Ikonos or WorldView satellite image derived bathymetry. Multibeam data collection targets waters from 20 meters to 500 meters depth. LiDAR and satellite derived bathymetry target waters less than 20 meters depth. The goal of all data collection is to collect data over the entire seafloor within the 0-500 meter depth range. Data artifacts may exist in the individual rugosity datasets as a result of problems associated with the original satellite imagery or with merging satellite-derived or LIDAR bathymetry with the multibeam bathymetry. These specific issues are captured and documented with the individual island files. Accuracy Horizontal positioning system: GPS C/A Horizontal position accuracy: typically 25 meters (refer to individual metadata files for each island for specific accuracy based on data sources used) Range resolution of sonar: varies with depth Raw sounding resolution: varies with depth Vertical accuracy of gridded product ~ 1% of water depth Completeness Report Rugosity values were determined for all areas where gridded bathymetry data was available. Some gaps exist in bathymetry coverage due to hazardous conditions that prohibited access for the NOAA vessels or to limited time or funding resources. Conceptual Consistency Multibeam bathymetry data were collected by different NOAA vessels using the same or similar collection methods. All multibeam data processing was conducted in the same or similar manner by the PIFSC Ecosystem Sciences Division. The MHI bathymetry synthesis provided by the Hawaii Mapping Research Group was the source data for the Main Hawaiian Islands products. The method to develop the geomorphological data layers are generally described in the Benthic Habitat Mapping "Overview" section of the Pacific Islands Benthic Habitat Mapping Center website. Rugosity: Cell values reflect the surface area and (surface area) / (planimetric area) ratio for the area contained within that cell’s boundaries. They provide indices of topographic roughness and convolutedness (Jenness 2004). Distributions of fish and other mobile organisms are often found to positively correlate with increased complexity of the seafloor. Investigations of which of the many methods available for quantifying benthic complexity best correlate with fish distributions in Pacific coral reef ecosystems are underway. Results of the Jenness (2004) method are provided as a standardized and well-documented interim product. Jenness, J. S. 2004. Calculating landscape surface area from digital elevation models.
