The new people are going into different work teams.

When you do service on heavy vehicles, you sometimes have to work from below, so why not make your own service pit. Chris just finished his addition to his workshop.

Some of the new people are an addition to the drilling team. They now have enough staffing to go into drill shifts on Monday. The new people in the ice core handling are receiving training in ice core logging and are beginning to setup equipment in the science trench. Four members of the MAGPIE project are working in the carpenters garage to unpack and mount their equipment. In the beginning of next week they will begin to make magnetic measurements at a cluster of points around EGRIP. On the deep ice core science side, a visible ash layer was observed at 1805 m depth. It is most likely from an eruption in Kverkfjöll in Iceland 33,700 years ago, just after the onset of Greenland Isotope Interstadial 6 (IS 6). This layer has also been observed in the NGRIP and NEEM ice cores.

What we did today:

1. Drillers made a three runs producing beautiful cores.
2. Logging ice cores. Logging depth: 1820.6 m.
3. Station for atmospheric moisture sampling and isotopic measurement is active.
4. The isotope CFA laboratory measured from bag 2738 to bag 2771 (1505.35m to 1524.05m).
5. The four MAGPIE project members are unpacking and setting up equipment.
6. Lifted the weather station of the PROMICE project, downloaded data and upgraded instruments. Station is ready for another year.
7. Recorded the snow accumulation of the past year along the skiway.
8. Removed snow blocks from access tunnel to increase roof clearance.
9. Repaired leaks in radiator systems on both Pistenbullys.
10. Repaired skiway markers.
11. Outhouse replaced.

Ad.1: Drillers are training new crews. The plan is to begin drilling in shifts on Monday.

EGRIP population is 28.

Weather this today: Fine. Temp. – 14 °C to -26 °C. Wind: 4 kt to 8 kt from WNW to WSW. Visibility: Unrestricted.
