75744 Data Set Published / External 75715 Story Map: NOAA Fisheries West Coast Offshore Scientific Surveys Project In Work 2025-05-01 This layer is intended to represent the geographic extent of NOAA Fisheries’ Pre-Recruit Survey transects. The collaborative Pre-Recruit Survey started in 2011 and is led by NMFS Northwest Fisheries Science Center. This survey includes researchers from NOAA’s Northwest Fisheries Science Center, Oregon State University, University of Oregon, and the University of California, Santa Cruz. This consistent survey has generated significant information on within- and between-year variability in the California Current Marine Ecosystem and has yielded valuable insights into the food web off our coast. Parameters and ecological processes quantified during this effort are used in forecasts involving species, assemblages, and ecosystems and also to parameterize ecosystem models used to evaluate cumulative risks and managerial strategies. Annual surveys are conducted within the coastal ecosystem off Oregon and Washington. At all stations a Cobb Trawl at 30 m is towed. Data on hydrology, plankton, small fish, and predators are collected along transects over the continental shelf from Oregon and Washington. Specimens are collected for diet analysis, growth, containment load, and other studies related to the ecology and production of commercially important taxa and their relationships within the food web. 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.
