Spatial-temporal changes of hydrophysical and hydrobiological characteristics in the North-West Black Sea shelf are considered using the last 50 year time series with more detailed analysis of certain periods. The results show significant temperature and salinity trends for the winter season. Temperature substantially increased about 2°? in the surface level of 0–10 m, and more than 3°? in the benthonic level, moreover, the vertical density gradient has doubled. Also, an increasing level of organic forms of nitrogen has been observed. It is found that qualitative and quantitative structure of phytoplankton depends on the seasonal and long-term changes.
