Nick Walker took part in a demonstration with the Norwegian Coast Guard to test the feasibility of using satellite derived sea ice information at high latitudes in the Arctic Ocean for navigation purposes. The icebreaker, KV Svalbard, travelled north into the sea ice reaching a latitude of over 82 degrees. A key factor was the timeliness of getting data to the vessel in these conditions. Sea ice is constantly moving because of winds, currents and tides. So the position of the ice may have changed from that shown in a product if it has taken several hours to arrive. The development of the data integration and visualisation system has been supported by the European Commission funded project, POLAR ICE, led by eOsphere.
