Deep substrate model (100m) of the Pacific Canadian shelf

This deep water substrate bottom type model was created to aid in habitat modeling, and to complement the nearshore bottom patches. It was created from a combination of bathymetrically-derived layers in addition to bottom type observations. Using random forest classification, the relationship between observed substrates and bathymetric derivatives was estimated across the entire area of interest.

The raster is categorized into: 1) Rock, 2) Mixed, 3) Sand, 4) Mud
