  • Seafloor Slope, 5m - Tutuila, American Samoa

    Pacific Islands Ocean Observing System (PacIOOS)

    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 degrees) in elevation between neighboring cells derived with the ArcGIS Spatial Analyst…
