Abstract

The main goal of the work is to study the spatiotemporal structure of sea currents in the shelf–slope zone of the northeastern part of the Black Sea. The studies were carried out by numerical simulation methods using the combined hydrodynamic and spectral wave models incorporated in the DHI MIKE computational complex. The model has been verified based on the data of field observations performed by means of the hydrophysical test site of the Institute of Oceanology, Russian Academy of Sciences (Gelendzhik test site). As a result of calculations with a discreteness of half an hour, the fields of velocities and directions of currents for the period from January 2016 to December 2020 were obtained. Despite the fact that the total length of the massif is insufficient for climatic generalizations, analysis of the data obtained from the numerical experiment makes it possible to judge some general features of the seasonal dynamics of waters. As a result of the work that was carried out, the features of current velocity fluctuations in the frequency domain were revealed, and, based on the averaged current fields, the main seasonal features of water circulation in the shelf zone of the northeastern Black Sea coast were estimated.
