One of the first Soviet hydrophysical Aist probes, an automatic salinity and temperature meter, was constructed in 1968 at the P. P. Shirshov Oceanology Institute of the USSR Academy of Sciences. The Aist probe is designed for automatic measurement and recording of the vertical distribution of the temperature and electrical conductivity of seawater down to a depth of 3.5 km from a drifting ship. The apparatus includes a submersible measuring probe and an on-board system. Information is transferred to the on-board system and the supply voltage is fed to the submersible probe by means of a single-core cable. Information arrives on board in the form of a serial pulse code with fequency filling. Decoding and conversion of the information take place in the on-board system by means of code-code and code-analog converters. The data are recorded in graphical form with two-coordinate potentiometers and in digital form on a tape puncher and in magnetic storage.
