Shifting patterns in Pacific climate, West Coast salmon survival rates, and increased volatility in ecosystem services.

The author discusses research which examines the dominant patterns of co-variation in survival rates of hatchery-origin Chinook and coho salmon populations from southeast Alaska to California. Topics include climate variations aspects of Pacific climate and salmon population dynamics, the correlation of dominant survival rate patterns with the North Pacific Gyre Oscillation (NPGO) sea surface temperature pattern, and the effect of Pacific Decadal Oscillation (PDO) on salmon production.
