Abstract

An instrument, the Cyclesonde, is described which consists of a buoyancy driven platform with a recording package containing sensors for pressure, temperature, current speed, and current direction. The Cyclesonde makes repeated automatic round trips up and down a taut-wire, subsurface mooring while scanning these four parameters with a 26-s sampling interval. According to the adjustable vertical speed ranging between 2 and 20 cm s-1, a vertical resolution ranging between 0·5 and 5 m can be achieved. The usage of the Cyclesonde is presently limited to the upper 200 m in the ocean and a maximum of 300 cycles (600 profiles) during a 5·5-day period. Selected sequences of typical profiles of various parameters are presented.
