The Cyclesonde - A Practical Profiler for Upper Ocean Current and CTD Measurements,

Pagination or Media Count:
The Cyclesonde is an automatic autonomous vertical profiling device which rises and falls on a taut wire mooring making measurements on both the ascending and descending part of its profile cycle. About 30,000 velocity profiles have been recorded by Cyclesondes to date which is believed to be more than all other methods combined. Most of these recordings have been made during more than a dozen oceanographic experiments on continental shelves and in the upper 200-400 meters of the deep ocean. The remainder supplied crucial information during the installation of the largest offshore platform ever built COGNAC in the Gulf of Mexico at a depth of over 300 meters, Collipp et al. 1979. The discussion below will briefly cover the evolution of the Cyclesonde, the design philosophy, sampling errors and possible future direction.
