Source Data: Groundfish data are from the NMFS U.S. West Coast Groundfish Bottom Trawl Survey (https://www.nwfsc.noaa.gov/research/divisions/fram/groundfish/bottom_trawl.cfm) and were downloaded from the FRAM data warehouse at https://www.nwfsc.noaa.gov/data/map with the following API query:Â https://www.nwfsc.noaa.gov/data/api/v1/source/trawl.catch_fact/selection.csv?variables=program,trawl_id,date_dim$year,date_dim$yyyymmdd,vessel,performance,year_stn_invalid,depth_m,latitude_dd,longitude_dd,scientific_name,common_name,species_category,partition,total_catch_numbers,total_catch_wt_kg,cpue_kg_per_ha_der,cpue_numbers_per_ha_der,"actual_station_design_dim$station_invalid_survey_year", "actual_station_design_dim$reason_station_invalid","reason_stn_invalid (target station)", "year_stn_invalid" Additional Calculations: Ratio of groundfish and crab scavengers to total biomass for the West Coast shelf and slope.
