13/12-14

Position: 88° 10.4' N, 82° 04' W, temperature - 23° C, air pressure 1008 hPa, wind 18 knots from the NNW. Ice drift 0.4 knots towards south. The air gun stopped in the early morning. Also, the hydrophone signal got swamped by noise trains. Serviced the air gun and also the air pressure reduction valve. Resumed seismic shooting at 1830 hours. Ambient noise level still too high, pulled the hydrophone to just below the underside of the ice to obtain good results.
