ABSTRACTModern methods of reconstruction of past climate variability allow now to study the decadal variability in the essential ocean climate variables at unprecedented resolution and accuracy. Firstly a new classification of estuarine and anti-estuarine regimes has been carried out my means of basin mean energy budgets with respect to wind and buoyancy forcings. Secondly the Mediterranean Sea circulation structure has been revisited and characterized. The re-analysis allowed to depict accurately the Northern Ionian Sea Reversal and the decadal strengthening of the Levantine circulation, together with the water mass formation variability. Finally the mean sea level tendency equation has been reformulated and the balances of terms show that the mean sea level tendency is dominated by a stochastic like contribution due to the mass balance in the basin at seasonal time scales added to the steric, almost periodic terms.
