Today, thanks to the hard work of everyone, the complete casing has been put in place down to a depth of 120 meters. This achievement was made possible by the efficient procedure that was devised yesterday. It only took about 20 minutes to bring one heavy casing tube from the surface down to the trench floor and fix is to the existing casing.
Christmas preparations have also taken place at LDC. Calogero and Michele, in the good old Italian furniture tradition, constructed a comfortable sofa for our recreation tent. Also, the entire LDC team has gathered outside for the Holiday Season group photo.
BEOIC drilling depth at the end of the day: 130.0 m
After some very small but important modifications at the RADIX drill tip, we have had a very successful drilling day with a total of 44.3 meters. The drilling speed was about 12.4 mm/sec, which kept us busy with feeding the ice-silicone oil slurry into the recycling system. We have also prepared the sampling program for the Beryllium-10 measurements on the chips. These analyses will provide additional information on the age of the ice and will be performed by the Swedish partners of BEOIC.
Radix drilling depth: 159.9 m
