PC53B:
Oceanic Climate and Ecosystem Variability and Change in Eastern Boundary Upwelling Systems II


Session ID#: 36883

Session Description:
Coastal climates along the major oceanic eastern boundaries are governed by a complex interplay of alongshore winds and clouds shaped by topography, ocean upwelling and eddies. These factors combine to yield marine ecosystems that are highly productive and diverse, and at the cutting edge of major climate trends including hypoxia and acidification. Future projections of the climate and ecosystem response of EBUS to global change are compromised by poor resolution of the scales of coastal variability. We invite studies of EBUS based on observational analysis and high-resolution earth system models, aimed at characterizing patterns of variability and detection and attribution of trends in climate and ecosystem processes. Studies that identify mechanisms of variability and change are especially encouraged.
