Ocean Ecosystem Indicators of Pacific Salmon Marine Survival in the Northern California Current
Long-term monitoring of ocean conditions and their effect on juvenile Pacific salmon survival off Oregon and Washington
Ocean Indicators - In development
Since 1996, the Northwest Fisheries Science Center has monitored the ocean environment off the Washington and Oregon coasts, its interaction with the California Current, and how ocean conditions affect fisheries, with a focus on Pacific salmon.
From a suite of oceanographic data, we identify climate and atmospheric, local physical, and local biological indicators that characterize the changing ecosystem experienced by juvenile salmon entering the northern California Current. We rate each indicator on whether the conditions for juvenile salmon survival are “good”, “fair”, or “poor”. These ratings are compiled into a “stoplight” table that can be used to forecast adult salmon returns.
