Tide gauge-based sea level variations since 1950 along the Norwegian and Russian coasts of the Arctic Ocean: Contribution of the steric and mass components
International audience We investigate sea level change and variability in part of the Arctic region over the 1950-2009 period. Analysis of 62 long tide gauge records along the Norwegian and Russian coastlines shows that coastal mean sea level in these two areas was almost stable until about 1980 but...
