Sun and ground fog
By midnight, the sun is rather low in the horizon and the ground fog is arriving.
Today we had ground fog and snow in the morning, but later it cleared up and became as nice as yesterday. As the Skier planned for today was cancelled, we had a normal working day with silty ice drilling, brittle ice processing, and pallet building.
The drilling is very difficult as penetration is hampered by the silt in the ice and we have a suspicion of being close to bedrock. A brutal-force technique was applied as a grinder was lowered into the hole to make way through the difficult material. Surprisingly, the next drill run came up with 10 cm of almost clear ice, so we may not be at bedrock yet.
Drilling: 0.10 m, drillers depth: 2522.08 m
Logging: 0.07 m, logger’s depth: 2537.36 m
Processing: 24.20 m (bag 1601-1644), processing depth: 904.20 m
What we have done today:
1. Drilling and core logging ice.
2. CFA packing.
3. Processed brittle ice.
4. Building science gear pallet.
Weather: In the morning ground fog and snow, but later mostly blue sky, low winds from S, and temperatures dropping to -20 deg °C at night. After midnight we got ground fog again.
