Abstract :

In this talk we will discuss the problem of sea ice extent (SIE) melting for Arctic Ocean. We took functional data approach to understand the problem. The analysis of mean function of SIE over different year blocks and 95% bootstrap confidence interval bands for Arctic Ocean shows a statistically significant drop in SIE. During the summer, the SIE is observed about 30% less in the current year block than that of first year block. We also developed a forecasting model to forecast the size of the Arctic sea ice cap. With this model we tried to forecast possible time frame by which the Arctic Sea Ice cap disappear.
