Downloadable DataBathymetric Position Index (BPI) Zones 5 m grid derived from gridded bathymetry of Rose Atoll, Territory of American Samoa, USA.
Metadata Thumbnail BPI Zones are derived from a focal mean analysis on bathymetry and slope. The grid is based on gridded (5 m cell size) multibeam bathymetry, collected aboard R/V AHI merged with seafloor depths derived from multispectral IKONOS satellite imagery. BPI Zon...
Downloadable DataRugosity grid derived from gridded bathymetry of Rose Atoll, Territory of American Samoa, USA
Metadata Thumbnail Rugosity is derived from gridded (5 m cell size) multibeam bathymetry, collected aboard R/V AHI, and bathymetry derived from multispectral IKONOS satellite imagery. Cell values reflect the (surface area) / (planimetric area) ratio for the area contained w...
