Abstract
The TOPEX/POSEIDON and ERS-1/2 satellite altimetry missions have revealed significant low-frequency changes of sea level in the North Atlantic Ocean. This work describes the changes that occurred from 1993 to 2001. Decomposition of total variance in three main modes of variability - annual, inter-annual and high frequency (basically eddies) - has been performed. As the analysis has shown, the annual and inter-annual signals are responsible for a greatest portion of variability in the northern North Atlantic outside the North Atlantic Current and its branches. In the areas where the inter-annual change is found to be significant, the sea level change followed the North Atlantic Oscillation index when it changed from its positive phase to negative in winter of 1995 - 1996 and 2000–2001.
