The first deep ice core of 2019 season

Steff, J.C. and Trevor with fresh 3.49m core in logging cabin.

Tonight, the first deep ice core of the 2019 season was drilled. One run produced a 3.49m ice core in one piece. As the deep ice coring is the main activity of EGRIP, it marks a special day. In the coming days, the drillers will fine tune the system and get into a routine mode. The cores will be stored in the ice core buffer awaiting the ice core processing team that will arrive on June 19. This morning, we said good bye to the PARCA team that left for Constable Pynt. We also said good bye to Dorthe, Maria, Frederik and Hans Christian who left with Polar 5 to Kangerlussuaq with shallow ice cores and samples and cargo.
