Abstract: Present study aims at the investigation of long-term satellite derived images of Earliest Melting Onset Date (EMOD) and Latest Melting Onset Date (LMOD) to study the sea ice variability in the Arctic. By applying cluster classification technique on the images of EMOD and LMOD, clusters having similar tendency were retrieved. The locations of centroids of the clusters revealed a distinct pattern showing tendency of clusters towards the early/delayed onset of melting. It was observed that the clusters having larger differences between EMOD and LMOD fell within the ocean area that became ice-free in September 2007. This study indicates that similar analysis using information on the onset of melting over the recent past (1998-2009) may help to predict the ice-free vulnerable zones in the coming 6-8 years.
