Abstract:

The design of the Draper Laboratory Profiling Current and CTD Meter PCM is described. This self-propelled instrument processes and records signals from its sensors in a programmed depth-time sequence. Its most noteworthy features are an energy-efficient buoyancy control system for sustaining cyclic vertical motion throughout long-term immersion accurate measurement of current, temperature, and conductivity in the surface wave field and a microprocessor-centered programmable electronic system for sophisticated control of operational functions. The prototype system is configured to operate unattended on a mooring line while drawing its power solely from internal batteries. It is presently being evaluated in near-surface ocean pilot experiments.
