Marine Ecosystem Services

CCE research uncovered how long-term climate changes markedly affect the California Current System, among the world's most economically important ocean regions. Fish habitat and other important ecosystem services are affected by reduced oxygen levels, warmer surface waters, diminished zooplankton populations, and decreased water transparency.
