Position: 89 01.8' N, 137 5.3' W, temperature - 17 C, air pressure 1023 hPa, wind 8 knots from SE. Ice drift 0.2 knots toward southeast. Shooting seismic reflection all day. We could see on the seismic record that the top cover of sediments (c. 200 m thick) was thinning and sediments below an underlying angular unconformity was likely to be exposed at the sea bed. Dropped the small gravity corer at 1000 hours targeting a suspected exposure. Had problems with the capstan drum so the core was not recovered until 8 hours later. Recovery was 20 cm. of very cohesive light brown sediments. No significant ice activity observed today.
