16/10-14

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. The 12 kHz echo sounder is giving us problems with weak or no bottom returns - recovered the transducer. In the evening. we spotted lights at a distance. Turned out to be a submarine at the surface in position: 89 17.5' N, 172 42.9' W. We were not able to identify it.
