The goal of this project is to improve current parameterizations of air-sea gas transfer for high wind speeds. This will involve continued field work in hurricanes during the 2008-2009 seasons. We also participated in the UK SOLAS Deep Ocean Gas Exchange Experiments (DOGEE), which involved two experiments in the North Atlantic (winter 2006 and Spring 2007). The data from these cruises are being used to validate our new water-side O2 covariance measurement technique based on fast-response O2 measurements on the floats.
