“…The initial temperature and salinity for the Black Sea basin were taken from Black Sea Marine Forecasting Center (BSMFC) (http://mis.bsmfc.net:8080/thredds/catalog.html). We chose BSMFC product because our preliminary analysis (Kholod et al., 2018; Mizyuk et al., 2018) showed better values of cal/val metrics for the MHI Black Sea MFC products (Black Sea Marine Forecasting Center of MHI) compared to the CMEMS (Copernicus Marine Service) one. For the Sea of Marmara the initial conditions are taken from the product of the Global Ocean reanalysis of CMEMS (http://www.marine.coperniucs.eu/).…”

This paper reports the water temperature structure and associated coastal processes in the NE part of the Black Sea. In situ temperature was measured in the water area of the Utrish Nature Reserve. The thermistor chain was moored in 2020 and included 6–10 temperature sensors with an accuracy of ±0.025 °C and time step of one minute. The seasonal variations in the water temperature, upwelling events, internal waves and diurnal cycle were analyzed. The maximum value of SST (28.6 °C) was registered in the subsurface layer in August 2021; the minimum (7.7 °C) was registered in March 2022. Estimates of the diurnal temperature cycle were obtained according to spectral analysis. Summer months show the diurnal cycle more than 60% of the time, and the cold period shows it less than 10% of the time. Internal waves appeared in thermocline with periods from 5 min to 20 h. The strongest Ekman upwelling was registered in September 2021. The water temperature dropped from 26 °C to 16 °C in 10 h. Additionally, quality assessments of two hydrodynamic models were made. The models showed a good correlation (0.9) with water temperature measurements, but RMSE could reach 1–1.8 °C for subsurface layers. Temperature variability and its characteristics are an important basis for future coastal ecosystem studies in the Utrish.

The paper considers the matters of numerical modelling and forecast estimation accu-racy of sea surface temperature in the two monitoring and forecasting centers of the Black Sea – in Federal State Budget Scientific Institution «Marine Hydrophysical Institute of RAS» (FSBSI MHI) and Copernicus marine environment monitoring service. The CTD (Conductivity Temper-ature Depth) profiling data of in situ measurements from research vessel “Professor Vod-yanitskiy” were used to solve the problem. Spatial and temporal mismatch between the model data and in situ measurements was eliminated to form a joint sample of these two data sources. Comparison was performed for the time period from October 2017 to September 2018 and showed that the forecasting results of sea water temperature in FSBSI MHI are more reliable than in Copernicus marine service for all forecast terms.
