Abstract:

   The metrological and space-time sound velocity characteristics of the profilograph are considered in the article. The sound speed sensor is considered in detail, its water exchange in the measuring base at various immersion velocities has been studied. A dynamic correction of the vertical profiles, connected with the movement of the device, has been carried out. The profiles of sound velocity in which their vertical stratification of the order of several centimeters are given. Recommendations on the use of the instrument in full-scale conditions from the shipboard are given.

Keywords: temperature, sound speed, method, salinity, error, modeling, dynamic characteristics, gradient.
