In recent years, the Black Sea experiences some significant climate change related issues; A distinct water masses defined by cold water cooler than eight degree Celsius was not generated during last couple of years in the Sea (Capet et. al, 2014; Miladinova et al., 2017; Stanev et. al, 2019), surface and the sub-surface temperature (50 m) has warming trend in recent decades (Sakalli 2018; Ginzburg et. al, 2004), and the deep salinity of the Sea is also increasing. A high-resolution circulation model based on NEMO was set-up for the Black Sea to better understand the possible effects of the climate change on the Black Sea dynamics. The model results have revealed the importance of the Bosphorus Strait input, and variability of the water masses during the model integration period.  

Figure shows the temperature profiles from the ARGO floats around the Black Sea exit of the Bosphorus Strait. There is relatively warm water outflowing into the interior of the Black Sea.
