The U.S. West Coast Groundfish Bottom Trawl Survey started in 1998 and is led by NMFS Northwest Fisheries Science Center. This survey provides long-term time-series data for the management of West Coast groundfishes as well as coastwide environmental sampling for monitoring change within the California Current Ecosystem. The bottom trawl survey covers West Coast waters (55-1280 meters [30-700 fathoms]) twice annually using a trawl net and a random sampling design, stratified by depth and latitude. The survey collects fishery-independent data on abundance, distribution, and biology of most species included in the west coast groundfish management plan. Weight and measurements are collected from vertebrates and invertebrates alongside various biological samples. Samples collected include otoliths and other structures for aging, finclips for genetics, gonads for reproductive analysis, and stomach contents and tissue samples for diet/stable isotope analysis. Oceanographic sensors are affixed to the trawl net, collecting data such as temperature, salinity, and dissolved oxygen for each trawl at depth. This data product is intended to help communicate the geographic extent of NOAA Fisheries’ scientific surveys on the continental margin of the U.S. West Coast. NOAA Fisheries conducts numerous scientific surveys to inform the status of fish stocks and protected resources. For the West Coast Region and Pacific Fisheries Management Council, more than a dozen surveys are conducted routinely across the continental margin, focusing either on pelagic or demersal species or the ecosystem as a whole. They collect a variety of biological and environmental data to provide a synoptic view of the habitats and ecosystems for which the target species inhabit. The surveys utilize varying designs including fixed stations where a number of operations are centered, transect lines where fishery acoustic data are continually collected, and stratified random sampling, to name a few.

The data was filtered using a definition query of `SurveyNum = 1 And SampleType = 'trawl'` to isolate trawl samples from the WCGBTS. The dataset was then uploaded to the NOAA GeoPlatform as a Feature Service for display on NOAA Fisheries West Coast At-Sea Scientific Surveys StoryMap.
