Easy drilling continues; we wish a happy birthday to Andreas; the loggers reach bag 500

After a slightly slow start with four cores under 3 m in length, we changed the drill head to one with freshly sharpened cutters, and then continued the day with six cores of over 3 m, to reach a daily total of a little over 30 m. Nice easy drilling!

Today we wished Andreas, our Italian Army nurse, a happy birthday. Andreas is the emergency medic on site to provide immediate cover for any accidents, before transfer to the doctors and medical facilities at Concordia Station. Fortunately, we have not had any incidents that required his attention.

The last drill run of the day brought up ice core bag number 500, meaning 500 m depth on the loggers’ depth scale. It was a bit late in the day for a proper celebration – that will likely come tomorrow at the drillers’ depth of 500 m.

End of day statistics:

Individual runs of the drill were recorded as: 2.52, 2.84, 2.60, 2.49, 3.19, 3.16, 3.25, 3.21, 3.41, 3.41 m

  • Drillers’ depth: 497.18 m; daily total 30.48 m
  • Loggers’ depth: 501.40 m; daily total 30.37 m
