A day with exchange of many people in camp
The warm CFA lab in the cold science trench is a surely complicated and integrated system and the inside of the box reminds me of modern art.
Today was a lucky day and we received the skier at 10:00. 15 new people arrived, 8 left us. It is sad to say goodbye and wonderful to say hello.
All teams in camp have changed and the day has been spent instructing newcomers in the tasks. There has been a fantastic positive and eager atmosphere in the whole camp.
What we have done today:
1.Drilling with the NEEM long drill: 18.19 m. Drillers depth: 1069.89 m
2. Logging depth 725.9 m
3. CFA analysis: 1.65 m. Depth: 332.75 m.
4. Receiving Skier 73. The mission was very successful, the ground time was only 50 minutes even though we received 3 pallets, loaded 3 pallets and received fuel from the skier. Thanks to the crew for a very professional and efficient mission.
5. Preparing shallow drill
6. Preparing the firn-gas and ice structure activities
7.Overhaul of generator to be used by the shallow ice core projects
8. Improvement of entrance to drill trench
Ad.1: Driller’s Report July 12, 2009: “With the arrival of the remaining drillers two full shifts have again been established. Over the last day and a half the inclination has stabilized between 2 and 2.1 degrees.
Adjustments with shims under the shoes with new cutters gives stable runs of 3.45 meters per core beginning with a pitch of about 2.8 mm and ending with a pitch of about 1.7 mm. To begin balancing the fluid density in the borehole pure Coasol is being added to the recycled drill fluid as space in the mixing barrels permits. Once these barrels are emptied a 2:1 Coasol:Estisol mixture will be used until a balance in the hole is reached. Driller’s depth (at 19:30 local) is 1066.45 meters.”
Weather: sunny most of the day with low clouds passing overhead a few times. Surface temperatures from -10 to -1°C.
