Daily Reports

Position: 83° 39.7' N, 15° 32.5' W, temperature - 9° C, air pressure 1025 hPa, wind 6 knots from the SE. Ice drift 0.0. Checked the radiation flux instrument. Data logger had stopped and battery voltage 3.7 volt. Changed battery and restarted logger. Deployed the underwater camera into the scattering layer - first at 22 meter depth and then at 55 meter depth. Abundant activity, but no good images captured beyond what we already have.

Position: 83° 39.7' N, 15° 32' W, temperature - 7° C, 1030 hPa, wind 4 knots from the SE. Ice drift 0.1 knot to the SE. Made a CTD cast down to 1000 meter. Returned to the thermistor site. Got the thermistor positioned vertically in the access hole so we could use the hovercraft winch to pull the Kevlar up and the mooring wire out of the ice. Everything came out with no damage. Drove back to camp. Had a shower in the sauna. The generator had to run all day to get enough water from melting snow.

Position: 83° 41.1' N, 15° 38' W, temperature - 10° C, 1025 hPa, wind 5 knot knots from the E. Ice drift 0.1 knot towards the SE. Went back towards the mooring site, but the hovercraft got stuck on an ice ridge underway. Had to jack the craft up to remove the ice ridge. Came loose, but got stuck two more times in ice rubble and had to use the winch to get out. . Drove back to camp in the evening

Position: 83° 42.7' N, 15° 48' W, temperature - 10° C, 1016 hPa, wind 10 knots from the NW. Ice drift 0.2 towards SE. Drove the hovercraft out to the site of the thermistor string mooring. Found the top of the mooring under an ice block at the edge of the pressure ridge. Drillen an access hole 40 cm away and hooked on to the string and pulled it up. Got everything up on the ice except thermistor # 1. Drove back to camp for the night.

Position: 83° 47.7' N, 16° 08' W, , temperature - 12° C, air pressure 1013 hPa, wind 13 knots from the WSW. Ice drift 0.3 knot to the SE. Poor visibility in the morning, but clear sky most of the day. Made a CTD cast down to 1000 meter.

Position: 83° 50.0' N, 16° 12' W, temperature - 13° C, air pressure 1005 hPa, wind 12 knots from the ESE. A beautiful day. Replaced the full data storage on the weather station. The display on the replacement cartridge is blurred and unreadable. Battery voltage was 7.35 volt. Added two D-cells to get 10.3 volt out. Drove the hovercraft to the location of the displaced thermistor string. The mooring was separated from camp by a shear zone only a meter or two away and displaced over 150 meter to the east.

Position: 83° 50.9' N, 16° 06' W, temperature - 7° C, pressure 1019 hPa, wind 5 knots from the NW. Drove over to the current meter site and continued the search. The current meter suspended at 800 meter depth is lost. Moved over to the ADCP mooring. Drilled a hole 7 meter from the mooring, but did not reach through. Made it through 2 m. thick ice 10 meter away. Lowered the camera, but no sign of an instrument. This is in a pressure ridge and even if we could spot the ADCP, we probably would not have been able to recover it. Moved the last

Position: 83° 51.7' N, 16° 14.4' W, temperature - 11° C, air pressure 1019 hPa, wind 4 knots from the NW. Clear sky - a beautiful day. Ice drift 0.1 knot towards the SE. We loaded the hovercraft and drove over to the current meter mooring. Drilled all together five holes and inspected the underside of the ice with the underwater camera. Much to our surprise, there was no trace of the kevlar line coming out of the ice. Returned to camp.

Position: 83° 52.7' N, 16° 25' W, temperature - 11° C, 1021 hPa, wind 11 knots from the SW. Ice drift 0.2 knots to the SE. Beautiful weather all day, but reduced visibility in the late evening. Made a CTD cast down to 1000 meter. Audun made a ski trip and recovered bathymetry buoy #1 from 4.3 km out. He also spotted two Ivory gulls on the way. Washed part of the superstructure that had deposits from the stove pipe accumulated through the winter. Also cleaned the deck around the compressor.

Position: 83° 58.2' N, 16° 37' W, temperature - 14° C, 1016 hPa, wind 15 knot knots from the NW. Ice drift 0.3 knot towards the S. The camera was lowered to 22 meter. The field of view was straight downwards, but did not capture any life in the two hours of recording. Made a CTD cast down to 1000 meter depth.
