In preparation for moving the rig for hole 1D, drilling and science crews worked to break the drill rig free from the lake ice and spillage around the rig. This was done to see if the rig could be hydraulically jacked up a few centimeters in such a way that we could eventually move the rig as one unit using a bulldozer, after we finish the bedrock sequence in hole 1 C. The jack-up worked well and the entire rig now sits on pieces of wood. Even the few skeptics among us are now very optimistic. The plan is to put sections of dented HQ pipe under the runners and roll the rig on the pipe with one dozer to the new position some 10m from the old hole. The successful jack-up test means that we should be able to move the rig easily and in the shortest amount of time to start drilling hole 1D and replicate the sediment section below -150m.
