Possible Changes in the CCS Associated with Global Climate Change
Potential Impact: Decreased zooplankton production and prey for higher trophic levels (fish)
- Decreased inflow from the north and total transport in the CCS
Potential Impact: Decreased survival and recruitment to coastal fish and invertebrate populations because of increased offshore transport of larvae and/or dispersion of prey organisms.
- Increased intensity of upwelling, offshore transport and mesoscale activity
Potential Impact: More frequent and stronger disruptions of “normal” conditions, favoring different species adapted to disturbed environments; periodic warmer than average temperatures; perhaps regime shifts.
- Altered frequency and intensity of ENSO events
Potential Impact: Shifts in major biogeographic boundaries; altered recruitment rates of coastal species through changes in the effectiveness of larval transport; increases in warm water predators altering mortality patterns and rates.
- Increased average sea surface temperature (1-2°C) and increased stratification of the water column
