27/12-14

Position: 87° 47.4' N, 64° 42' W, temperature - 36° C, air pressure 1023 hPa, wind10 knots from the southeast. Ice drift 0.1 due east. Shooting seismic reflection all day. Cleared a place for the tent which for now will be an addition to our present work space. This was a cold day and we had to take the tent floor inside the cabin to heat it before it was laid out. The tent was difficult to unpack, but doable. We connected to our air supply and the air filled support arches inflated nicely, but the structure folded after a few minutes from loss of air pressure. After several tries, we located a leak where the hose joint the end cap of the center roof beam. It appears to be a problem related to the cold and O-rings not sealing well enough. Also, the air gun stopped firing. It was recovered and the solenoid taken apart and cleaned. Back in the water, the gun was leaking air. We took it inside for the night as the ice drift was very slow. Now, the moon is again visible over the horizon.
