ETOPO5 Global Surface Relief
ETOPO5 is a 5 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry. It was built from numerous global and regional data sets.... -
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,... -
Main Hawaiian Islands Multibeam Bathymetry Synthesis: 50-m Bathymetry and Topography
A 50-m resolution gridded synthesis of all available bathymetry (ocean depth) data for the main Hawaiian Islands, including ship-borne multibeam sonar surveys, from the Hawaii... -
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)... -
Seafloor Slope, 5m - Tutuila, American Samoa
Slope is derived from gridded (5 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hiialaka'i and R/V AHI, Cell values reflect the maximum rate of change (in...
