Arctic Sea Ice Polar AVHRR

The purpose of this page and column is to track significant sea ice fracturng events north of Greenland and Ellesmere Islands using AVHRR imagery.
The AVHRR imagery is from the Canadian Environmental Ellesmere-Polar webpage:
 
 
Review the images below from the bottom up to visualise the ice fracturing from Feb 20, 2013 to date.
 
 
Ellesmere Island AVHRR
 
The following fracture which created a line practically from Ellesmere past the North Pole seems to also be related to a storm which passed over the North Pole. The following series shows the before and after imagery with the storm captured in this process. The progression is from earlier to later imagery.
 
February 15, 2013 0229 - New pattern in place
 
February 14, 2013 1948, fracturing change underway
 
February 14, 2013 1249 Storm moving south from the NP.
 
February 13, 2013 1119, The black is a storm from the south crossing the Pole.

The following fracture event was over 525 miles in length, and may have happened in about 8 minutes. It seems associated with a SLP that moved over the Pole on Feb 9-12, 2013.
