                         Monthly Mean Sea Level (MSL) from 22 ports in the extra-tropical 
                         North Atlantic with 30 years of uninterrupted data {{(1957-1986;}} 
                         30°N {{}} 78°N) were examined by empirical orthogonal function 
                         (EOF) expansions and spectral analysis of principal components by 
                         two methods, with the three first EOF's explaining 58% of the 
                         total variance. To extend the results well into the interdecadal 
                         band, two series representative of the first two EOF's (44% of the 
                         total variance) were used with 95 years of monthly data without 
                         gaps (1893-1988) on opposite sides of the North Atlantic basin. We 
                         suggest that we can identify the signature of the Great Salinity 
                         Anomaly (GSA) and North Atlantic Oscillation (NAO) in the MSL 
                         data. Most of the energy in the anti symmetric {{{"}seesaw{"}}} 
                         mode is in the interdecadal band, with peaks around periods of 3, 
                         5-6, 14, 17-19, 28 and 57 years. These results were compared with 
                         those obtained from long series of other climatic indices and 
                         recent model results obtained by other authors.",
