Groundfish species richness

Groundfish data are from the <a href="nwfsc.noaa.gov/research/divisions/fram/groundfish/bottom_trawl.cfm" target="_blank">NMFS U.S. West Coast Groundfish Bottom Trawl Survey</a> and were downloaded from the FRAM data warehouse at nwfsc.noaa.gov/data/map <a href='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"' target="_blank">with this API query</a>; Additional Calculations: Species richness for groundfishes on the West Coast from the West Coast Groundfish Bottom Trawl Survey.

Data underwent sample-based rarefaction and were then scaled to a set number of individuals (*standardized for sampling effort) to produce richness estimates.
