An experimental system for monitoring the dynamics of temperature changes in the coastal zone was tested at the oceanographic platform in the village of Katsiveli (Crimea) continuously for more than a year from 2021 to 2022. The created system was based on three distributed temperature sensors (thermoprofilometers) identical in design and electronics (thermal copolymer), vertically installed on the spatial basis of an equilateral triangle with a side of 18 m. Continuous spatiotemporal data on vertical temperature profiles up to a depth of 19.5 m were obtained. Data correlation of simultaneous measurements of sensors with pronounced dynamics of temperature gradients allowed to calculate, in addition to the amplitude and period of oscillatory processes, the length, velocity and direction of internal wave propagation. Measurement data with pronounced time fronts of temperature changes made it possible to calculate the direction and velocity of transfer of water masses on horizons. Software algorithms for automatic calculation of specified parameters for correlated indicators of spatiotemporal displacement of calculating isotherms have been developed. The results of the experiments proved the possibility of using a system with the specified technical characteristics of thermoprofilometers installed on a spatial basis limited by the dimensions of the oceanographic platform to measure the parameters of internal waves and temperature variability with pronounced fronts.
