Double Walled Pit

The logger calibration dance by Derryn and Trevor.

Today the repair of the new DK logger was finished and we calibrated it outside away from magnetic sources. Derryn and Trevor danced with the logger turning and rotating it in all angles while Dorthe under her jacket programs the calibration.
Eliza, Ilka, Meg and Jinhwa found a spot 1.1 km from camp in the clean area and dug a 1.9 m deep pit for tephra and O18 sampling. After sampling they dug in from the other side creating a 20-30 cm thick wall.
After dinner most from the camp visited the site and enjoyed the beautiful firn wall with quite a lot of melt layers from the last 4-5 years. We enjoyed a cup of warm chocolate made by Chiara at the site documented with the drone operated by Martin.
In the evening JP sent us the image from flightradar24 showing how the first skier arrived to Kangerlussuaq and circled around the very foggy airport before aborting and flying towards Iqaluit in Canada. None of the skiers made it to Kangerlussuaq this Tuesday so we are crossing fingers for better luck tomorrow. Our mission is on Friday so no worries.

What we did today:

1. Calibrated new DK logger.
2. Lowered rock drill to bottom to vacuum clean borehole.
3. Repaired top plug and slip ring on drill.
4. Groomed apron.
5. Prepared Flexmobil for transport to Kangerlussuaq.
6. Packed drill boxes.
7. Dug a 1.9 m deep pit for tephra and O18, made it doubled walled.
8. Evening excursion to the double walled pit.

Weather today: Low clouds and groundfog in the morning clearing during the day to scattered clouds and blue sky in the evening. Wind between 1 kt and 8 kt turning from W to N during the day. Temperatures between -15°C and -6°C.
