A NEEM science meeting

Everything you need for a perfect time off: Sunshine, skis and a kite

Today a ‘science meeting' was held in camp where many of the available NEEM profiles were presented in preliminary versions. Due to the many online analyses performed in camp and impressive amount of profiles were presented: Model results of the Greenland ice sheet evolution based on the newest NEEM data, methane gas concentrations of the glacial period in unprecedented resolution, bag-mean water isotopes, DEP, ECM and linescan intensity profiles, as well as fabric and grain size results from selected depths.

The big question is of course what to think about the deepest part of the ice core, but it is difficult to be conclusive at this stage.

Drilling: 8.08 m, drillers depth: 2394.52 m.
Logging: 7.43 m, loggers depth: 2410.79 m.
Processing: bag 1271-1319 (25.30 m), 723.80 m.
CFA: bag 3662-3697 (19.80 m), 2033.35 m.

What we have done today:
1. Drilling and core logging ice.
2. Processed deep ice cores.
3. CFA measurements.
4. Celebrating Tim's 50 years birthday.
5. Having a science meeting.

Weather: Clear blue sky, winds around 10 knots from SSE and temperatures -17 °C to -6 °C.
