Slope cell values indicate the maximum rate of change (in degrees) in elevation between a given cell and it's neighboring cells. This data set is for three banks located southwest of Guam, Territory of Guam, USA. 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 NOAA Ship Oscar Elton Sette, a 224’ (68 m) research ship.

Slope was calculated in degrees and a z-factor of 1 was used. The slope was calculated separately for the three banks included in this map, using the following input surfaces: gal_5m_100, sgal5m and ele5m.
