The controlled flux technique (CFT) uses heat as a proxy tracer for gases to measure air-sea gas transfer rates. It has been used during the MBL/CoOP West Coast experiment in April/May 1995 aboard R/V New Horizon for the first time at sea. In this paper the technical realization of the sea-going instrument is outlined and first measurements of the gas transfer rate in the field are shown. The high temporal resolution reveals that the gas transfer rates are intermittant with respect to space and time. Depending on surfactant concentration and the patchiness of surfactants they vary up to +-25% of their temporal average for a certain wind speed within some minutes.
