Saturday evening

Celebrating the Swiss national day

The Swiss National Day is celebrated

Today is the Swiss national day so we had a Swiss evening. Thanks to Suzanne, Uhrs, Adrian (Swiss guy) and Robert for an excellent meal. The table was decorated with Swiss flags and a green apple with an arrow for Wilhelm Tell. No further details – except – we celebrated Kumiko’s birthday (02 August) at midnight with layered cakes, a birthday song and dancing.

What we have done today:

1.Drilling with the NEEM long drill: 11.78 m. Drillers depth: 1461.04 m
2. Logging 11.04 m of core. Logging depth 1474.62 m
3. CFA analysis: 3.30 m. Depth: 582.35 m.
4. Processing 19.8 m. Processing depth: 1433.3 m (bag 2606)
5. Showers for all
6. Installed kitchen mill in kitchen sink

Ad 4: The glacial to interglacial transition. ECM from NEEM is compared to the ECM from the NGRIP core. Based on the match and the NGRIP annual dated transition 11.704 to 11.701 B2P the transition in the NEEM core is predicted to be at the depth 1418.80m. Line scan of the 3.3 m section shows clear cloudy bands in the colder glacial Younger Dryas ice to the right – see photo below. For the gas sampling the special transition sampling started with bag 2580 (T1). The gas transition sampling will continue to T170 and then return to the original sampling program.

Weather: A sunny and windy day. Blue sky, temperature between -13 to -7°C. Wind 12-16 kn from SSE.

ECM data from the ice core
The glacial to interglacial transition seen in the ECM data from the NEEM ice core is compared and matched to the ECM transition in the NGRIP ice core. The bottom picture showns the line scan results over the transition.
