Position: 87° 23.7' N, 64° 03' W, temperature - 18° C, air pressure 1014 hPa, wind 17 knots from ENE. Ice drift 0.1 towards SSE. Put the air gun back in the water at 0200 hours, but the short section of air hose attached to the gun burst. The gun fired at half a meter depth in the hole and we were soaked and the whole room sprayed with ice water. Changed hose and continued seismic reflection measurements all day.
