Daily Reports

Position: 88 52.7' N, 121 48.7' W, temperature - 18 C, air pressure 1015 hPa, wind 3 knots from ENE. Ice drift 0.1 knots toward east. Shooting seismic reflection all day.

Position: 88 53.1' N, 122 55' W, temperature - 19 C, air pressure 1019 hPa, wind 8 knots from SE. Ice drift 0.4 knots towards southeast. Shooting seismic reflection all day. Recovered the rock dredge at 0200 hours. The dredge contained two small rock pieces, most likely glacial erratics. We drifted out of the canyon during the evening. Dropped the corer on a ledge in 2930 meter water depth and recovered 1 meter of brown mud, probably all recent sediments. Submitted and uploaded via internet the final revision of our paper to Journal

Position: 88 53,8' N, 124 32.7' W, temperature - 19 C, air pressure 1024 hPa, wind 9 knots from E. Ice drift 0.2 knots towards east. Shooting seismic reflection all day. We are moving along the lower slope and start crossing a canyon. The rock dredge is out.

Position: 88 54.1' N, 129 32' W, temperature - 17 C, air pressure 1022 hPa, wind 8 knots from NE. Ice drift 0.1 knots towards northeast. Shooting seismic reflection all day. The rock dredge is out.

Position: 88 57.7' N, 132 22' W, temperature - 21 C, air pressure 1022 hPa, wind 4 knots from NE. Ice drift 0.2 knot towards northeast (back across Lomonosov Ridge). Acquiring seismic reflection data all day. We are moving upslope. Dropped the dredge in 26660 meter of water. Audun is working on getting our sauna finished.

Position: 88 49.6' N, 134 32' W, temperature - 10 C, air pressure 1016 hPa, wind 13 knots from the NNE. Ice drift 0.1 knots towards northeast. Shooting seismic all day. We just reached the foot of slope of Lomonosov Ridge in the Makarov Basin. The ice drift now turns back up the flank of the ridge. Recovered an empty dredge # 4

Position: 88 55.2' N, 134 37' W, temperature - 11 C, air pressure 1016 hPa, wind 23 knots from SSE. Ice drift 0.5 knots towards southsoutheast. Dropped dredge # 4 to the seabed at 2400 meter depth just after midnight just in case any rock
exposures would appear. Shooting seismic reflection all day. No significant ice activity observed .

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.

Position: 89 06.6' N, 140 44' W, temperature - 16 C, air pressure 1017 hPa, wind 15 knots from SE. Ice drift 0.4 knots towards southeast. Shooting seismic reflection all day. Audun discovered a new 3 meter wide crack in the ice only 5 meter behind the hovercraft in the morning. The crack stopped widening and closed later in the day with some shear motion. Audun packed up the 3.5 kHz echo sounder in case we had to relocate. We are on top of Lomonosov Ridge approaching the edge on the Makarov Basin side.

Position: 89 11,5' N, 146 06' W, temperature - 14 C, air pressure 1029 hPa, wind 10 knots from ESE. Ice drift 0.1 knots towards southeast. Shooting seismic reflection all day. Recovered dredge # 4 at 1900 hours. Twelve fist sized rocks and one platy fragment in the bag, probably all glacial erratics. Deployed camera sled in 1390 meter water depth on top of Lomonosov Ridge at 2300 hours
