Electromagnetic-laser ice thickness data collected by helicopter and ice distribution data collected with Video-laser sensors from ArcticNet 1b survey leg of the summer 2013 in Kennedy Channel of Nares Strait

The BO105 helicopter on board the CCGS Amundsen was used during the northern section of the ArcticNet 1b leg to collect the ice thickness and video data along flight paths across Kennedy Channel. The main collection of data was done on three days between August 21 and August 24. In addition a total of 5 beacons were deployed on thick ice floes during these flights to monitor the ice drift of the floes within Kennedy Channel. From the two data sets the ice flux through Kennedy Channel can be estimated as shown below. At the end of the survey, ice thickness data was collected with an EM sled from a floe in Barrow Strait (74.0N and -96.4W) on September 1, 2013.
