SUMMARY
In this paper, the seasonal and interannual variability of global and oceanic mean sea level variability are studied through a decomposition approach in the framework of the singular spectrum analysis (SSA) of available time series of sea level anomalies that extend back to 1993.The results show that the global mean sea level variability is dominated by an increasing trend. The rate of the global trend as seen by SSA appears to be about 3.36 mm/ year during the period 1993-2015. However, the trends from the different ocean regions show dissimilar patterns. The major contributions to the global sea level rise during 1993–2015 are from the Indian Ocean (3.80 mm/year).
