On the Long-Term Mediterranean Sea Level Variability

The present study focuses on the long term variability of Mediterranean Sea level variability. 14 long series of tidal heights were considered in this study to find out the long term trends in the sea level along the Mediterranean shores using Mann-Kendall test and Sen’s slope estimator. One advantage of Mann-Kendall test is that the data do not need any particular distribution. The second advantage of the test is its low sensitivity to abrupt breaks (change-points) in the time series. Sen’s method uses a linear model to estimate the slope of the trend (change per unit time). The identified yearly trends using these tests for more than fifty years of data point clearly and unequivocally towards the same conclusion that is the Mediterranean Sea level has risen since the end of the 19th century.
