Position: 87° 22.0' N, 63° 23' W, temperature <- 40° C, air pressure 1012 hPa, wind 14 knots from WSW. Ice drift 0.1 knots towards the east. We put the air box in place and closed all openings between the work space and the hovercraft superstructure. Also connected the Zarges box with the stove. It is very cold today, so in between you often have to go inside and warm up.
