Juvenile Salmon and Ocean Ecosystem Survey (station)

This layer is intended to represent the geographic extent of NOAA Fisheries’ Juvenile Salmon and Ocean Ecosystem Survey stations. The Juvenile Salmon and Ocean Ecosystem Survey (JSOES) started in 1998 and is led by NMFS Northwest Fisheries Science Center. This survey is the longest running salmon survey on the U.S. West Coast. The primary goal of our work is to develop a mechanistic understanding of how trophic dynamics and conditions in the ocean and Columbia River plume affect survival of juvenile salmonids. JSOES collects juvenile salmon and other open-ocean animals which allows identification of shifts in abundance, distribution, and growth/condition of migrating juvenile salmon. JSOES has demonstrated correlations between ocean conditions and the distribution, abundance, and survival of juvenile Columbia River salmon in the Northern California Current nearshore ecosystem to provide context for efforts by states, tribes, and others to restore and enhance salmon production. The samples from this survey improve salmon forecasts in a quantitative rather than qualitative manner, and decouple the effects of mitigation efforts in the freshwater environment from the effects of a changing ocean environment. The survey is conducted two times a year (late May and late June) for roughly ten days each. This study utilizes a surface trawl. A surface trawl collects juvenile salmon and other open-ocean animals during sampling.

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.
