nwfscSurvey provides code for analysis of the Northwest Fisheries Science Center (NWFSC) West Coast Groundfish Bottom Trawl, NWFSC slope, Alaska Fisheries Science Center (AFSC) slope, and AFSC Triennial surveys. Code within this package allows for pulling of data from the NWFSC data warehouse, calculating the design-based indices of abundance, visualization of data, and processing length- and age-composition data for use in West Coast groundfish stock assessment.

This code was developed for use by scientists at the NWFSC and is intended to work on the specific data products that we have access to using methods specific to the needs of this group.
