RESPONSE OF OCEAN ECOLOGY TO CLIMATE CHANGE: AN INITIAL IPCC AR5 EARTH SYSTEM MODEL INTER-COMPARISON

We assess the response of ocean ecology to 21st century climate change across some of the new IPCC AR5 Earth System Models. These models have very different ocean ecology modules, resulting in different phytoplankton community structures and complexities, different surface chlorophyll and productivity, and ultimately different ecological responses to climate change. Here we provide an assessment of climate driven changes in the extent, productivity, community composition and organic matter export across the major biogeochemical provinces in the ocean in our model suite. We observe different phytoplankton behavior in the Northern and Southern Hemisphere subpolar and subtropical gyres; we verify whether this hemispheric asymmetry is driven by the different shifts in the midlatitude westerlies in the Northern and Southern hemispheres. We employ both old and new tools and metrics to relate trends in stratification, mixing and wind patterns to changes in ecology and biogeochemistry under climate change.
