Description: We overlaid commercial groundfish fishing effort (based on West Coast Observer Program data, 2002 - 2010) for the bottom trawl, midwater trawl and select fixed-gear fleets with benthic habitat types off the coast or WA,OR, and CA, out to the 1,600 m isobath. Benthic habitat was classified into nine categories, which combined attributes of three depth strata and three bottom hardness categoroes. The depth strata were shelf, upper slope and lower slope. Bottom hardness was classified as hard, mixed or soft. Weighting for each of the nine benthic habitat categories was assigned based on fleet type (bottom, midwater, fixed line and fixed point). The model grain was a gridded 2 x 2 km surface. Each gridcell represent data from three or more unique vessels over the modeling time frame (2002 - 2010). Details of this model can be found in the EFH Phase II report and associated appendices.
