21/3-15

Position: 85° 30.7' N, 38° 22' W, temperature - 35° C, air pressure 1027 hPa, wind 5 knots from the S. Ice drift 0.1 knot to the SE. Had 12 volt supply off from midnight to mid-day as part of checking why our power consumption is so high. The seismic data logging PC with its old battery was the problem - removed the battery and connected the power supply to a 12 volt battery on the engine side. Serviced the air gun and started shooting at 1400 hours. Changed battery on the radiation flux instrument data logger.
