Position: 85° 24.4' N, 37° 24' W, temperature - 34° C, air pressure 1011 hPa, wind 7 knots from the N. Ice drift 0.1 knot towards S. At 0230 hours, we suddenly woke up to the sound of ice ridging - the 100 meter wide lead next to the hovercraft was slowly closing. The 15 cm thick new ice on the lead was now piling up as rubble where the hydro hole was. We started winching while running the engine at maximum power and 50% forward thrust. The hovercraft came slowly up the incline out of the snow pit. The ice activity stopped in the early morning when the lead had narrowed down to 10 meter.
