Southern Ocean plays a dominant role in the uptake of anthropogenic carbon. \u0026nbsp;However, the air-sea flux of CO2 in the Southern Ocean is poorly represented by models, thus its future trajectory remains highly uncertain. \u0026nbsp;In this talk, I describe an ambitious observational campaign: The O2\/N2 Ratio and CO2 Airborne Southern Ocean Study (ORCAS), which aims to advance our understanding of the physical and biological controls on air-sea exchange of O2 and CO2 in the Southern Ocean. \u0026nbsp;ORCAS flew aboard the NSF\/NCAR Gulfstream V aircraft over a period of 6 weeks Jan-Feb 2016, performing intensive airborne surveys of atmospheric O2, CO2, related gases, and ocean surface properties. \u0026nbsp;The campaign covered diverse biogeochemical regions adjacent to the southern tip of South America and the Antarctic Peninsula. \u0026nbsp;Observations of O2 and CO2 ratios demonstrate the dominance of biology in driving the zonal mean air-sea flux. \u0026nbsp;Preliminary results indicate CO2 distributions that are inconsistent with published estimates of air-sea CO2 flux, suggesting that the summertime Southern Ocean is larger sink for CO2 than previously recognized.\u003Cbr \/\u003E\r\n\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIf you are interested in talking with Dr. Long, please contact Hollie Meyer
