Purpose. The purpose of the study is to assess the trends in a change of the Black Sea thermohaline structure on the interannual time scales in 2000-2020 based on three reanalyses performed using different methods, as well as direct observations. Methods and Results. Four datasets are applied to perform the research. The first one is an array of temperature and salinity profiles on a regular grid with a 10-day time resolution and a 10′ × 15′ spatial resolution for 2000-2021, which is based on the data of 13952 oceanographic stations. The second set is formed according to the results of reanalysis carried out using the MHI Black Sea circulation model. The ERA-5 atmospheric reanalysis results are used as an atmospheric forcing. The satellite data on sea surface temperature and altimetry are assimilated in the model. The third dataset represents the reanalysis results obtained based on the NEMO model regional configuration. The atmospheric forcing is also preset using the ERA-5 reanalysis results...
