Usage

Arguments

survey

A character entry from one of the following options that specifies which survey to pull the data for. The input options are: Triennial, AFSC.Slope, NWFSC.Combo, NWFSC.Slope, NWFSC.Shelf, NWFSC.Hypoxia, NWFSC.Santa.Barb.Basin, NWFSC.Shelf.Rockfish (not yet working), NWFSC.Hook.Line (not yet working), NWFSC.Video, Triennial.Canada The National Marine Fishery Service Alaska Fisheries Science Center (AFSC) Triennial survey was conducted between 1977 - 2004 occurring every 3rd year. The initial year, 1977, survey is not traditionally used in calculating indices of abundance. The Triennial survey sampled areas within the Canadian EEZ on the West Coast of Vancouver Island in 1980 - 2001 but these data are associated with a different survey name "Triennial.Canada". The AFSC Slope Survey (AFSC.Slope) along the west coast of the U.S. began in 1984 and occurred annually from 1988-2001, with the exception of 1994 and 1998, when surveys were not conducted. Prior to 1997, only a limited portion of the coast was covered in each year. U.S. West Coast groundfish stock assessments only use the four years of consistent and complete survey coverage (1997, 1999-2001). The Northwest Fisheries Science Center (NWFSC) Slope survey (NWFSC.Slope) was conducted between 1998 - 2001. The NWFSC West Coast Groundfish Bottom Trawl survey (NWFSC.Combo) is conducted annualy starting in 2003 (excluding 2020) and samples both the U.S. west coast shelf and slope between 55 - 1,280 meters. Data can only be pulled from one survey at a time, though we are working on allowing for a vector of survey names. Currently, NWFSC.Shelf.Rockfish and NWFSC.Hook.Line are not supported.
