AbstractIn this study we investigate the contribution of individual oceanic regions to the global mean sea level change (mean trend and interannual variations) observed by the satellite Topex-Poseidon from 1993 through 1999. This allows us to analyze sea level change in regions not primary influenced by short-term climate fluctuations, in particular the 1997-1998 ENSO event. We report that the sea level in the southern oceans (here defined as the region between 60°S and 30°S) has been rising between January 1993 and December 1999 at a rate of 1.0+/-0.1mm/yr and 1.7+/-0.1mm/yr between December 1994 and April 1999. This rise is positively correlated with an increase of sea surface temperature and thus could reflect a warming of the southern oceans waters.
