Bent at his workbench in the Dome, working on the new drill electronics section.

Passing the 500 meter mark

In a deep drilling operation it is always a goal to find a stable and reproducible mode, bringing up section after section of beautiful ice core. Unfortunately we are struggling to find such a routine. Our hope is, that we can get there by making the new electronics section for the ice core drill work. With this new section the drillers will have a better overview of how the drill performs at depth. Despite of the challenges, the drilling now passed the 500 m mark, which loggers and drillers celebrated together.

On the surface, a lot of items were moved to garages for storage as the wind picked up during the day, and the surface team continued the science program. Further progress was also made in the science trench were both physical properties measurements and CFA water isotope measurements were carried out.

What we did today:

  1. Cleaned away various cargo from the surface.
  2. Deep drilling core length at 19.00: 8.21 m.
  3. Logging depth at 19.00: 503.44 m.
  4. Water isotopes: Depth 99.55 m.
  5. Fuel inventory: 16982 liters of fuel in camp plus 350 liters of mogas.
  6. Water vapour, methane, aerosols, snow and boundary layer measurements
  7. Physical properties measurements.
  8. Cleaning of core troughs.

Weather: Changing cloudiness during the day . Wind from WNW up to to 9 m/s. Temperature between -14°C and -7°C.
