Last core drilled this year at EGRIP was this Saturday. We have drilled nearly 300 m (2122.42 m to 2418.23 m) from 7 July to 6 August. This is a great success based on careful preparations bringing in a stronger winch motor, a new winch controller, a new cable and new cutters, shoes and core catchers for the drill head. A great CONGRATULATIONS to all drillers and especially Steff for preparing so well. Also, a great WELL DONE to all involved in removing snow blocks in the drill trench – we estimate 120 tons of ice blocks were removed before the drill activities could start. Tomorrow the science trench will finalize the processing of the 2022 ice cores. Just a great field season.

What we did this weekend:

1. Four drill runs from Friday 7 pm to Saturday 7 pm. Logger’s depth at 7 pm: 2418.23 m. Logged core: 8.25 m.
2. Processing in science trench. Last bag packed: 4384: Production: 34.65 m.
3. Seismic equipment at shear zone recovered and packed.
4. Pit samples for mercury sampled to 4 m depth.
5. White garage tent free and ready to lift.
6. Winter storage prepared.
7. 24 200l fuel drums placed on small wooden slegde and filled with fuel.
8. S3 borehole logging with Sepp’s temperature logger started.

Ad.1: the final cores have been drilled for this year. The runs on Saturday were with the DK Hans Tausen drill.
