Daily Reports

Position: 84° 11.3' N, 17° 59' W, temperature - 14° C, pressure 1032 hPa, wind 6 knots from the SSE. Sun from a clear sky all day. Ice drift 0.0 knot. Deployed the hydrophone for the sparker buoy. Got the control electronics checked out OK, but the sparker energy source kept blowing a fuse and the problem was not found. A more permanent location inside the work space was made for the generator.

Position: 84° 13.2' N, 18° 09' W, temperature - 15° C, 1024 hPa, wind 6 knots from the NW. Ice drift 0.2 knots to the SE. Sunshine from a clear sky all day. Audun went back to the site of buoy #1 and connected up the batteries. The old ones measured 5.5 V and 7.2 V, respectively. Removed the heat enclosure from the compressor and tidied up. Moved the sparker buoy into the work tent. Audun rechecked the radiation flux data logger and rebooted the program. Making pictures of the scattering layer.

Position: 84° 11.8' N, 17° 59' W, temperature - 16° C, air pressure 1029 hPa, wind 2 knots from the W. White-out from 0900 hours. Ice drift 0.1 knot towards the SE. Cleared the workspace from its connection to the hovercraft - only generator power line attached. Connected up the sparker buoy.

Position: 84° 18.3' N, 18° 42' W, temperature - 17° C, 1021 hPa, wind 14 knot knots from the NW. A clear day. Ice drift 0.2 knot towards SE. Audun restarted data logger on radiation flux instrument. He also made a ski trip with batteries to bathymetry buoy # 1 at 4.7 km out from our camp, but was missing a tool to complete the job.

Position: 84° 23.3' N, 19° 15' W, temperature - 18° C, 1025 hPa, wind 17 knots from the NW. Ice drift 0.2 towards SE. At 1600 hours, our seismic program had come to the end. Stopped data acquisition and pulled the air gun out of the water - last field file is # 40370. Take screen shot of the 50/200 kHz echosounder at least at local noon and local midnight.

Position: 84° 42.7' N, 20° 43' W, , temperature - 13° C, air pressure 1035 hPa, wind 22 knots from the W. White-out all day, but the sun became visible at 1700 hours. Shooting seismic reflection all day. Deployed the dredge in 1400 meter water depth over the southeastern edge of the spur. When recovered six hours later, the first few hundred meters of Kevlar line near the dredge was a mess and the dredge was empty. With this our geological sampling program on FRAM- 2014/15 came to an end. Audun visited bathymetry buoy #1 about 1.7 km out.

Position: 84° 29.0' N, 19° 46' W, temperature - 9° C, air pressure 1026 hPa, wind 6 knots from the NE. White-out all day. Ice drift 0.1 knot towards SE. Continue shooting seismic reflection.

Position: 84° 30.3' N, 19° 53' W, temperature - 11° C, pressure 1027 hPa, wind 4 knots from the NE. White-out all day. Ice drift 0.0 knot. Continue shooting seismic reflection. Recovered a short sediment core from 820 meter depth at the EE edge of the top of the spur. Reorganized our stock of eggs. Those that were closest to the outer wall in the flotation tank had been frozen and were cracked and had to be disposed of. About 120 out of 400 eggs left.

Position: 84° 32.2' N, 19° 54' W, temperature - 217° C, air pressure 1030 hPa, wind 14 knots from the NW. White-out all day. Ice drift 0.2 knot towards the SE. Shooting seismic reflection measurements all day. Dredge on the bottom 0340-1300 hours - returned only small angular fragment of lightly metamorphosed shist. Camera sled on the bottom from 1400 to 1840 hours. Saw small sand volcano adjacent to opening of two orifices in the bottom. Pumped fuel from the only bladder in camp to the rear tank which became 3/4 full.

Position: 84° 36.7' N, 20° 14' W, temperature - 14° C, 1030 hPa, wind 13 knots from the NW. Ice drift 0.1 knots to the SE. White-out all day. Shooting seismic reflection measurements all day. Recovered a short sediment core. Camera sled at the bottom 1230-1530 hours. Observed six fishes and small holes which may have been formed by venting of fluids. Also in places broken pieces of crust of light colored sediment. Deployed the dredge for two hours, but returned empty. Made screen shot of 50/200 kHz echo sounder every six hours.
