Dead batteries data logger, transducer fault with rev counter, chuck jamming after lowering into water, winch capstan creeping backwards and banging in neutral and braked.page 7 |
24 November |
Removed capstan to check on air in the system, replaced it and tested again with weights. Then ran a test using the TAE sledge as a weight. |
25 November |
Tested the winch using the TAE sledge plus the weights to 100 m. At 1830 hrs started to lower the Vibracorer, stopping every 100 m to readjust the Hiab which was sagging. At above 600 m the comms. cable broke, winched the Vibracorer to the surface by 220 hrs. Repair comms cable. |

Broken comms cable (D5),repaired. Lowered the Vibracorer down at 1500 hrs, reached the bottom at about 700 m and ran the Vibracorer through coring programme but the barrel did not retract the last 2 m. Vibracorer winched to surface to find the core barrel had been bent about 30 degrees. It took from 2200 hrs to 2400 hrs to remove the bent core barrel from the vibracorer. |
27 November |
DVs visit started drilling new hole about 30 m west of 1st hole, used the winch cable of D5 to saw between the holes. Katabatic winds in the evening. |
