Position: 86° 07.3' N, 45° 16' W, temperature - 22° C, air pressure 994 hPa, wind 3 knots from the NW. Ice drift 0.1 towards SE. A most welcomed "hot" day and opportunity for engine maintenance. Put a tarp over the engine bay and used the propane burner for heating. Adjusted the lift fan belt tension, greased all points and changed diesel fuel filters. We have lately been unable to get the engine to run over 1000 rpm, which turned out to be clogged fuel filters for the second time on the ice.

Position: 86° 07.6' N, 45° 16' W, temperature - 40° C, air pressure 1000 hPa, wind 1 knots from the N. Ice drift 0.1 knot to the W. Shooting seismic reflection, but little or no ice drift. Went to the old camp and broke loose the last 5 drums of Jet-A1 fuel from the ice. Took a 1.5 hour search for the bathymetry buoy nearest camp (500 m) , but did not find anything.

Position: 86° 07.5' N, 45° 29' W, temperature - 31° C, air pressure 1013 hPa, wind 7 knot from the NW. Ice drift 0.1 knots towards W. Operating the seismic reflection gear, but little or no ice drift. Freed two more drums of Jet-A1 from the ice in the old camp. Have received 5 cm of snow today.

Position: 86° 07.6' N, 45° 20' W, temperature -30° C, air pressure 1018 hPa, wind 3 knots from the NW. Ice drift 0.1 knot towards W. Shooting seismic reflection all day. Checked the radiation flux instruments and cleaned sensors. Have included the battery for the fan into the battery bank for the main engine to secure charging.

Position: 86° 07.6' N, 45° 05' W, temperature - 33° C, air pressure 1018 hPa, wind 9 knots from the NW. Ice drift 0.1 knot to the W. Shooting seismic reflection until 1200 hours. Hauled a drum of Jet A1 fuel from the old camp to the hovercraft to use for the stoves.
