The historical data series of 34 tide gauges located along the Mediterranean coast were analyzed using statistical trend tests.

The application of the Man Kendall test and its version which takes into account the presence of the seasonal component, shows that most of tidal stations have significant trends in sea level rise.

The annual rates of sea-level changes estimated by using the Sen’s approach are quite similar to those estimated by the Permanent Service for Mean Sea Level (PSMSL), thus demonstrating the adequacy of selected statistical tests and approaches.

The estimated rates of change point to the same conclusion: the Mediterranean sea level has risen since the end of the 19th century.
