| Abstract |
The successful implementation of some instrumentation programmes for acquiring marine environmental data are reported. The instruments are used for instantaneous measurements of water current and direction, salinity, temperature and depth of operation. Sensors with novel features were developed and used in water current meter and salinity -temperature-depth meter. The sensors designed with very low impedance and high level signal outputs have rendered the instruments to be quite reliable with comparatively simpler electronics. A sixteen channel data acquisition system designed for automatic of coastal environmental data is reported. |
