In 2008 a six-week research expedition aboard the NOAA Ship Ronald H. Brown was conducted with sponsorship from NASA, NOAA, and NSF. The Southern Ocean Gas Exchange Experiment departed Feb. 28 from Punta Arenas, Chile, and spent most of its time in the storm track east of the Southern tip of S. America (51 S 36 W). Scientists from dozens of universities and research institutions were on board to measure turbulence, waves, bubbles, temperature, ocean chemistry and biology, and investigate how these factors relate to the air-sea exchange of carbon dioxide and other climate-relevant gases. A consortium of researchers from NOAA/ESRL - U. Colorado, U. Connecticut, Columbia U., and U. Hawaii cooperated on comprehensive suite of instruments to make direct motion-corrected covariance and inertial-dissipation flux measurements and associated forcing variables such as near-surface bulk meteorology, surface waves and whitecap fraction. In this paper we report on analysis of the turbulent fluxes of momentum and water vapor and a comparison of the bulk transfer coefficients with the COARE algorithm (version 3.0).
