A good Saturday

Sections of ice waiting to be melted in the CFA melter
Birthe is preparing the next section to be melted in the CFA melter. Note the library of waiting sections in the shelf system in the snow wall.

Weather today was absolutely gorgeous. Sunshine, very little wind and nice and cold.

While morning and noon passed in usual routine, the afternoon saw quite some traffic in camp: Some were skiing, some walking and some enjoying the Sun. There was a
steady flow of people to and from our sauna to fresh up before Saturday night dinner.
Dinner tonight was Japanese style with lead cook Kumiko and assistance from Sato, Jocelyne, Maibritt, Anne and Romain.
The theme of dinner talk was that NEEM was on the right track and that it was very
satisfying to see the Worlds most complex CFA system ever brought to the field
actually was working.

What we have done today:
1. Drilling and logging.
2. Processing brittle ice cores. Processed 21 bags, from 2133 to 2153.
3. Grooming taxi way and apron with beam groomer.
4. Measuring CFA. Today we measured 19.8 m. Last bag 2543, 1398.65 m.
5. Making shelves and cabinets of laboratories.
6. Erecting flag line in main street of camp.
7. Setting up computer info screen in dining area. Everybody can now follow progress
    of drilling on-line.

Ad.1: Drillers report:
After one more filter run for good luck, two runs produced 6.27 meters for the abbreviated Saturday shifts. Chip recovery is not optimal. The packed pump will need service from Steff on Sunday morning to replace the spring loaded valve doors which came loose on the last run.
Cutting pitch is less than 2.0 mm. Pressure Tube "2" is performing nicely with drilling
current between 6.5 and 9.5 amps.

Drillers depth: 1868.88 m. Logging depth: 1878.59 m

Weather: Beautiful day and cold too. -28°C to -18°C, 2 -5 knots from SE, S and SW.
Visibility: Unrestricted.

FL, J.P. Steffensen
