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.
