ABSTRACT
Over the last decade many researchers have noticed an increasing of the annual average sea level which is associated with the general climate warming and the glaciers melting. Further rise could have a catastrophic impact on the environment and production activities of people in the coastal areas, in particular on the functioning of the port facilities. In the design and construction of the offshore structures it is necessary to know annual average sea water level during the last 50 years. Because of sea level is constantly increasing the trend in sea level must be taken into account. This paper focuses on presenting the results from analyzing mean sea level changes in the seas, surrounding the European part of the Eurasian. Data sets from 33 tide gauges covering the European coastline in the period approximately from 1880 to 2015 have been used to estimate the mean sea level time series. The results from smoothing and linear trend estimations are presented. It is noted the decreasing of the water level on the northern coast of the Baltic Sea and the Gulf of Bothnia and irregular increasing on the coasts of North, Adriatic, Balearic, Aegean and Black Seas.
