| 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. |
