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.
What We Do
How do ocean conditions affect ocean fisheries? 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.
2020 Ocean Conditions
Our ocean indices combine a suite of oceanographic data to capture the changing ecosystem. These indicators characterize ocean conditions experienced by juvenile salmon entering the northern California Current. We rate each indicator in terms of whether the relative impact on the marine survival of juvenile salmon is "good," "poor," or "fair".

Ocean Conditions Affect Salmon Returns
We analyze various ocean conditions to develop "stoplight" tables that can be used to forecast adult salmon returns.
