Position: 89° 09.0' N, 71° 44.5' W, temperature - 20° C, air pressure 1027 hPa, wind 27 knots from WNW. Ice drift 0.4 knots towards east. Shooting seismic reflection all day. This is the position of the outcrop of the major unconformity. Recovered the dredge, only one rock specimen with sharp edges recovered. The Kevlar line had disintegrated between 100 and 200 meter, we had to cut the line after recovering the dredge. Airgun started to fire only occasionally, had to recover the gun for maintenance. The through-going 3 meter wide crack had come together with build-up of a small pressure ridge. Could now reconnect power to the radiation flux instruments. The radiation instruments are fine, but the sun time and IP sensors had to be cleared for frost and snow.
