The 2010 OCB Summer Science Workshop was held July 19-22, 2010 at the Scripps Institution of Oceanography in La Jolla, CA. This Workshop highlighted three interdisciplinary science themes: Arctic, low oxygen regions, and benthic-pelagic coupling. Within these themes, we were especially keen to address nitrogen cycling, ecological tipping points, and strengthened connections between experimentalists and modelers.

Arctic
The Arctic is undergoing rapid changes in response to warming, accelerated melting of large ice sheets, and reductions in seasonal sea ice cover. This session will explore implications of these changes for marine ecosystems (e.g., primary production, food webs) and associated physical (e.g., salinity, stratification, deep ocean circulation, etc.) and biogeochemical (nutrient cycling, carbon fluxes, carbonate saturation state, etc.) processes.
Low Oxygen Regions
Many models are predicting a significant expansion of oxygen minimum zones under the IPCC “business-as-usual” scenario for anthropogenic CO2 emissions, which will affect marine productivity, carbon and nutrient cycling, and food webs. This session will highlight new observations and applications of biogeochemical and ecological tools and approaches to study processes within different low oxygen systems.
Benthic-Pelagic Coupling
Benthic and pelagic ecosystems are intimately linked by way of biogeochemical cycling and transformation. Benthic-pelagic coupling along continental shelves represents a significant unknown in coastal carbon budgets, and the physical, chemical, and biological processes driving organic carbon export and burial in the open ocean remain poorly characterized. This session will focus on new observations and tools to explore benthic-pelagic processes.
