An airborne system for measurement of the total heat flow from the sea has been developed and used successfully during the BOMEX exercises in May 1969. Details of the system are described, and its operation is illustrated by one day’s results at Barbados, W. I. Continuous recalibration of detector sensitivity was a major improvement which permits measurement of sea surface temperature to 0.01°C.
