Seafloor Rugosity, 5m - Tutuila, American Samoa
Rugosity is derived from gridded (5 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hiialaka'i and R/V AHI, using the Benthic Terrain Modeler with rugosity methods... -
Seafloor Slope, 40m - Swains, American Samoa
Slope is derived from gridded (40 m cell size) multibeam bathymetry, collected aboard R/V AHI, and NOAA ship Hi'ialakai. Cell values reflect the maximum rate of change (in... -

Seafloor Rugosity, 40m - Swains, American Samoa
Rugosity is derived from gridded (40 m cell size) multibeam bathymetry, collected aboard R/V AHI and NOAA ship Hi'ialakai. Cell values reflect the (surface area) / (planimetric... -
Bathymetric Position Index (BPI) Structures, 40m - Swains, American Samoa
Bathymetric position index (BPI) structures are derived from gridded (40 m cell size) multibeam bathymetry, collected aboard R/V AHI and NOAA ship Hi'ialakai, and it was created... -
Bathymetric Position Index (BPI) Zones, 5m - Tutuila, American Samoa
Bathymetric position index (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,... -
Bathymetric Position Index (BPI) Structures, 5m - Tutuila, American Samoa
Bathymetric position index (BPI) structures are derived from two scales of a focal mean analysis on bathymetry; slope; and depth. The grid is based on gridded (5 m cell size)... -
