Climate change, marine food webs and salmon in the northern California current
Producer - Michael Furniss
Videography - Ben Nieves
Technical production - Jeffrey Guntle
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.
