Mediterranean Sea level trends from long-period tide gauge time series

The main purpose of this study is to highlight， on the basis of statistical tests， the significant long-term changes of the Mediterranean Sea level， through the analysis of historical tide gauge records. In this framework， 14 tide gauge monthly series selected from the Permanent Service of the Mean Sea Level （PSMSL） database were used. The search for the presence or not of trends within these series， that have a temporal coverage from 59 to 142 years， was carried out using the Mann-Kendall test and the Sen''s slope estimator. The obtained results show that the Split Rt Marjana series are the only ones which does not exhibit a significant trend. The other 13 series show significant increasing trends. This result seems sufficient to suppose the presence， in the past century， of a new climatic phase on the scale of the Mediterranean basin， where the rising sea level is one of the consequences.
