8/7-15

Position: 82° 06.18' N, 09° 56.7' W, temperature -2 °C, 1028 hPa, wind 6 knots from the NE. Ice drift 0.1 knot to the SW. Activated two ARGOS trackers and the CMR buoy on the cargo stored on the pressure ridge, and started driving the hovercraft in the direction of Greenland. Had to stop after one hour because of vibrations when the propeller pitch is increased beyond 2/3 of full. Consulted with Griffon Hoverworks, UK, tightened the drive belt and continued. Got stuck on an ice ridge and had to winch out. At about midnight, we came into a very challenging area characterized by a mess of ice ridges and had to park. About 4 nautical miles had been covered.
