Abstract :
An instrument has been designed to record vertical current information. It does this by sequentially monitoring pressure, temperature, and rotation sensors. The data is stored on a digital cassette tape recorder. In addition, it generates a signal for acoustically telemetering part of the data. This permits a check on performance without the need for recovery. The instruments can be readily adapted to a wide range of sensors. Its original use was in the long range floats used in the Mid Ocean Dynamics Experiment (MODE I).
