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.  February 12, 2013 2152  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.

Arctic Ocean Composite AVHRR February 20 2013 0310 - two fractures run the entire Arctic Basin  February 19, 2013 0833 - further fracturing across the Chukchi and Beaufort plus a new semi-circular fracture in the Arctic Ocean from north of Wrangel Is across the CAB to Ellesmere.  February 17, 2013 1912 - the full fracture described form Feb 12-14 is visible along with a new long fracture across the Chukchi and Beaufort.  |
