Session ID#: 15141

Session Description:
The Southern Ocean is an important CO2 sink and biogenic gas source with unique sensitivity to climate change, yet large gaps remain in our understanding of the biogeochemical processes controlling present-day air-sea exchanges and carbon-climate feedbacks. Sparse observations and unique challenges to accurate modeling have been primary limitations.  Recent developments promise significant progress on both of these fronts. These include the 2016 O2/N2 Ratio and CO2 Airborne Southern Ocean (ORCAS) study; year-round biogeochemical observations facilitated by the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project; long-term observations from the Palmer LTER program, Drake Passage Timeseries, and Ocean Observatories Initiative; fully-coupled climate models, eddy-resolving biogeochemical ocean models and state estimates; and, finally, advanced algorithms for space and aircraft based remote sensing of chlorophyll, carbon, and major plankton groups. This session solicits results that leverage recent observational and/or modeling investments to advance our understanding of Southern Ocean biogeochemistry.
