Position: 87° 22.5' N, 63° 47' W, temperature - 30° C, air pressure 1019 hPa, wind 1 knot from the SSW. Ice drift 0.0 knots. Acquiring seismic reflection data until 0815 hours as we were out of air from loss of heat on the compressor. Started work on the generator to see if there was any hope of repair. The engine has to be opened from the generator side and the generator axle is pressed on to the engine drive shaft so special tools would be needed. Further pursuit of repair was considered futile. Audun made a hole for deployment of the thermistor string. The hole is to be lined with three plastic core liners bundled together and partly filled with ethanol. This will make recovery easy and avoid the fishing operation to catch the top of the string.
