SOGASEX
The Souther Ocean Gas Exchange Experiment is also known as GasEx III. The experiment took place in the Southern Ocean in austral fall of 2008 (February 29-April 12, 2008) on the NOAA SHIP RONALD H. BROWN. The research objectives for Southern Ocean GasEx are to answer the following questions: * What are the gas transfer velocities at high winds? * What is the effect of fetch on the gas transfer? * How do other non-direct wind effects influence gas transfer? * How do changing pCO2 and DMS levels affect the air-sea CO2 and DMS flux, respectively in the same locale? * Are there better predictors of gas exchange in the Southern Ocean other than wind? * What is the near surface horizontal and vertical variability in turbulence, pCO2, and other relevant biochemical and physical parameters? * How do biological processes influence pCO2 and gas exchange? * Do the different disparate estimates of fluxes agree, and if not why? * With the results from Southern Ocean GasEx, can we reconcile the current discrepancy between model based CO2 flux estimates and observation based estimates?
