Position: 86° 32.2' N, 50° 11' W, temperature - 33° C, air pressure 1013 hPa, wind 10 knots from the N. Ice drift 0.2 knot to the SE. Shooting seismic reflection all day. Our internal WiFi-network which distributes the GPS-signal to the different logging systems was down for about one hour. Audun continued exploring our small 800 W generator which will take a heavy load such as the grinder (600 W) , but not a small load such as battery chargers. The key is adjustment of the revolutions pr. minute. Also the wind mill stopped, the problem being the shaft ball bearing gets locked.

Position: 86° 37.2' N, 50° 28' W, temperature - 26° C, air pressure 1005 hPa, wind 11 knot from the NW. Ice drift 0.2 knots towards SE. Shooting seismic reflection all day. CTD cast down to 2.400 meter in 2.500 meter water depth. Each run takes about 3 hours with the hovercraft engine running. We have to conserve fuel and will stop making CTD casts from now on. We have obtained a transect with 13 casts over the Lomonosov Ridge. Blowing snow in the evening. Audun discovered a small crack running parallel to the hovercraft about 3 meters away.

Position: 86° 40.7' N, 51° 20' W, temperature - 33° C, air pressure 1012 hPa, wind 8 knots from the NW. Ice drift 0.2 knot towards SE. Shooting seismic reflection all day. Deployed the camera sled in 2.280 meter water depth. Unfortunately, the Kevlar laid out on the bottom had hooked on to the sled and pulled it sideways. Made a CTD cast down to 2.100 meter water depth. Also deployed the short sediment corer - had 0.6 meter penetration, but the core barrel came up empty.

Position: 86° 42.3' N, 51° 47' W, temperature - 40° C, air pressure 1018 hPa, wind 4 knots from the NW. Ice drift 0.1 knot to the south. Shooting seismic reflection all day. We are at the edge of the flat-topped ridge, water depth 1500 meter. Made a CTD cast down to 1450 meter at 1445 hours and another cast at 2300 hours to 2000 meter in 2080 meter water depth.

Position: 86° 43.2' N, 52° 00' W, temperature -36° C, air pressure 1015 hPa, wind 6 knots from the E. Ice drift 0.0 knot. Shooting seismic reflection all day. Checked out the radiation flux instrument and cleared the IR sensors for snow. Deployed the sediment corer in the early hours and obtained a 38 cm core for the Ice2Ice project. Audun went for a ski trip in the neighborhood. If the drift speed holds up, we are about to enter the 200 nautical mile zone north of Greenland in a day or so.

Position: 86° 43.3' N, 52° 43' W, temperature - 30° C, air pressure 1005 hPa, wind 9 knots from the W. Ice drift 0.3 knot to the E. Shooting seismic reflection all day. We missed out on deploying the rock dredge over a basement exposure on the sea bed. Worked all day to improve the hydro hole which was about to be closed by new ice. Made a CTD cast in the evening and deployed the camera sled. Upon recovery, the video footage showed the camera lights had gone into blinking mode and also the sled had been dragged sideways.

Position: 86° 46.7' N, 54° 51' W, temperature -32° C, air pressure 1001 hPa, wind 23 knots from the W. Ice drift 0.4 towards SE. Shooting seismic reflection all day. A snow storm outside makes problems to get inside the outer work space. Made one CTD cast in the early hours to 750 meter depth and another cast late at night to 850 meter depth. We also made two attempts to obtain a short sediment core, but the corer had no penetration and came up empty

Position: 86° 53.5' N, 57° 08' W, temperature - 24° C, air pressure |003 hPa, wind 11 knots from the W. Ice drift 0.3 knot to the SE. Shooting seismic reflection all day. Started work to raise the second current meter from 800 meter depth. The location is now 5 meter from a pressure ridge. Using the underwater camera, we saw the Kevlar line diverted away from the pressure ridge. To recover the instrument require drilling holes to follow the line until we reach the end of the under thrusted ice floe. This work has to be deferred until late spring/early sommer.

Position: 86° 57.2' N, 58° 57' W, temperature - 29° C, air pressure 990 hPa, wind 14 knot from WSW. Ice drift 0.4 knots towards SE. Shooting seismic reflection all day. Raised one current meter from 1.050 meter depth to 660 meter by drilling a hole and snagging the Kevlar line with a hook. Pulled the Kevlar through a pipe filled with ethanol to facilitate an easy new adjustment of the depth once we are off the ridge.

Position: 86° 59.8' N, 60° 33' W, temperature -32° C, air pressure 990 hPa, wind 16 knots from the NW. Ice drift 0.3 knot towards SE. Shooting seismic reflection all day. Deployed the camera sled in 1.150 meter water depth. The camera lights went to blinking mode at the bottom and made the run less useful. Made CTD cast down to 1.080 meter depth.
