Abstract

The monthly mean sea level at 19 stations and the monthly mean atmospheric pressure at 15 stations in the Mediterranean Sea are analysed to find the trend of the sea level and to identify the significant oscillations from the power spectral estimates. The results show that from the present data at Marseille, Trieste and Genova it is expected that the sea level tends to increase by 13 cm /100 years, which will affect the water budget of the area. The spectral analysis of the pressure could explain most of the oscillations in the sea level time series at 12, 6 and 4 months’ periods, except in the Adriatic Sea where the steric effect is expected to have an important contribution.
