Zipped data files contain 1) Arc ASCII file, 2) layer (.lyr) file for symbology, 3) high-res JPG of image, and 4) explanatory metadata text file (identical to linked file listed below).
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.

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)
