| Abstract: | A self-governing profiling system with a depth capability of 100 m has been developed for measuring flow velocity, temperature, salinity, and turbidity of water in the near-bottom parts of shelf seas. In the system, a moving profiler unit holding the sensors for measuring the above parameters and depth and containing a data-recording device is made to move up and down, in cycles, along a mooring line. This motion of the profiler unit is governed by a self-contained microprocessor. The system has been field-tested: examples of recorded data are presented. |
