Abstract: 
Using some results of the international geodynamic VLBI program for 1994—2010, the coordinates of the station Simeiz are determined. The measurement results for the Simeiz RT-22 coordinates are compared with long-term monthly-averaged measurements for the Black Sea level which are performed at the stations located in Odesa, Ochakov, Sevastopol, Yalta and Katsively. All the stations of the sea level measurements have a different water flow, which gives the opportunity to explore global geodynamic processes and a relationship between them and a solar activity cycle. A spectrum of sea level variations in various points shows the presence of periods from one to 11 and 22 years. The periods for each level station separately are estimated with the use of wavelet analysis.
