Like yesterday, drilling was fairly stable today. Still using the same set-up, we made 6 runs around 4 meters long. We get a run with very low chips recovery, then we changer hollow shaft, and it get better. Anyway, this afternoon we decided to make a filtration run after lunch time.

We are still successfully processing the ice cores and have now reached 1103m depth.

The whole Beyond EPICA field team whish you a Merry Christmas.
