2/1-15

Position: 87° 34.2' N, 65° 05' W, temperature - 27° C, air pressure 1020 hPa, wind 10 knots from ENE. Ice drift 0.1 southeast. Shooting seismic reflection all day. Noticed strong jerks repeatedly over several hours. The reason was active pressure ridging about 250 meter to the north of us. The area seems otherwise intact. At 1400 hours the generator suddenly lost AC-power output. Hauled out the new spare generator and started. It run for about 2 hours and suddenly stopped. The cause is no compression as one valve lifting rod is unseated. This is not repairable here.
