Substrate, Hard bottom vs. Soft bottom - 5 meter grid
Substrate : This is a preliminary product classified from sidescan and multibeam
bathymetry data. Cell values reflect whether the seafloor is hard or
soft. Please see the metadata for additional information.

Slope - 1 meter grid
Slope: Cell values reflect the maximum rate of change (in degrees) in elevation between neighboring cells. Slope was derived with the ArcGIS Spatial Analyst extension.

Rugosity - 1 meter grid
Rugosity: Cell values reflect the surface area and (surface area) / (planimetric area) ratio for the area contained within that cell’s boundaries. They provide indices of topographic roughness and convolutedness. (Jenness 2003)
