Description

This presentation looks at the effect of physics (water circulation patterns) on biology (food webs for salmon). Factors that affect plankton, food chains, pelagic fish and salmon include: large scale circulation patterns and kinds of water that feed the California current, seasonal reversal of coastal currents - southward in summer and northward in winter, coastal upwelling, and phase of the Pacific Decadal Oscillation (negative or positive).

You should gain an understanding of:

The critical physical and biological processes that link climate forces to salmon survival.

How we may assess the impact to salmon of impending climate change.
