The Lomonosov Ridge bottom at 2650 meters depth.

Position: 88 18.7' N, 157 08' W, temperature - 17 C, air pressure 1028 hPa, wind 12 knots from ESE. Ice drift 0.3 knot towards ESE (back across Lomonosov Ridge). Blowing snow all day. Acquiring seismic reflection data all day. The dredge is out with 3000 meter Kevlar in anticipation of shallower water early Monday morning.

Position: 89 20.4' N, 164 41' W, temperature - 13 C, air pressure 1034 hPa, wind 6 knots from the SE. Ice drift 0.2 knots towards east. Shooting seismic all day. Audun moving food box away from the large crack (7 m wide).

Position: 89 20.6' N, 168 43' W, temperature - 13 C, air pressure 1036 hPa, wind 3 knots from NE. Ice drift 0.15 knots towards east. Was finally able to recover the hydrophone. Redeployed the 300 meter long thermistor string in the vicinity of the radiation flux instrument. The radiation flux instruments have been without power for several days. Laid out a cable across the lead and started charging. Cleaned all detectors. Also the weather station was completely covered with frost, cleaned all detectors. A small crack is going in between the guide wires, but no significant movement seen.

Position: 89 19' N, 174 51' W, temperature - 8 C, air pressure 1036 hPa, wind 5 knots from E. Ice drift 0.1 knots toward east. Started recovery of the thermistor string as it is only 5 meter away from a crack that has widened 3 meters. The thin ice on refrozen leads are likely sites of future pressure ridge formation. Having recovered half (150 m), we discovered that the hydrophone was about to be consumed by the pressure ridge south of the hovercraft. Started to melt out the hydrophone, but was not successful.

Position: 8 17.6' N, 179 36' W, temperature - 9 C, air pressure 1031 hPa, wind 11 knots from ENE. Ice drift 0.3 knots towards east. We are drifting along the bathymetric contours of Lomonosov Ridge. Hovercraft maintenance all day; adjusting the lift fan belt. No ice activity observed.

Position: 89 08,9' N, 177 35' E, temperature - 14 C, air pressure 1031 hPa, wind 11 knots from ENE. Ice drift 0.2 knots towards northnortheast. Stopped the airgun at 0517 hours, we had a new crack through the ice on the port side about 20 meter away from the hovercraft widening several meters. Another crack 10 cm wide is parallel and passes 5 meter away from the craft. Hovercraft maintenance all day - replaced broken lift fan belt. Also removed the four jack-up legs and placed the hovercraft on four pallets. Felt a jerk of the ice floe.
