18/2-15

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. The crack went under one of the fuel bladders and the fuel was immediately pumped over to the hovercraft.
