The NCAR/NSF G-V O2/N2 Ratio and CO2 Airborne Southern Ocean Study (ORCAS) took place in Jan-Feb 2016 and was based in Punta Arenas, Chile. The primary goal of the study was to investigate the air-sea exchange of O2 and CO2 over the Southern Ocean where the uptake of anthropogenic carbon is a key process that is poorly represented by models. In addition to many long-lived gases, measurements of reactive volatile organic compounds (VOCs) were measured using the Trace Organic Gas Analyzer (TOGA) and advanced whole air canisters (AWAS), and are used to better understand and constrain air-sea exchange in the southern ocean region.
