Measuring CO2 in the Science Trench

A first picture of the methane and CO2 Picarro output: the monitoring of the CO2 content in the Science Trench. The trench is a busy place in day-time, but during the night the CO2 concentration drops. In the morning it increases again when work starts. The whole camp is summing happily and we had 2 big events to celebrate today: the CFA lab finished the measurement of the ice to the depth of 601.70 m where the brittle zone starts and the drillers passed 1500 m!

What we have done today:

  1. Drilling with the NEEM long drill: 21.65 m. Drillers depth: 1492.13 m.
  2. Logging 23.10 m of core. Logging depth: 1505.81 m.
  3. CFA analysis: 8.80 m. Depth: 601.70 m.
  4. Processing 23.10 m of core. Processing depth: 1472.9 m (bag 2678).
  5. Continuing to improve office with storage boxes along the sides.
  6. Building floor for sauna in the third garage.
  7. Flattening the camp area for snow drifts.

Weather: A sunny day with light haze at times. Blue sky, temperature between -17°C and -7°C. Wind: 10-14 kn from SE.
