Drilling progress is acceptable.

Drilling progress is acceptable. We now reached 1700 m drilling through softer rock, a dolerite with a deformed, but originally most likely intrusive contact to the overlying volcanic rocks. The mystery of seriously crooked drill pipes is haunting even this drilling (cf. problems at COSC-1). We quickly built a device for sorting out the worst scrap and hope that this will improve drilling performance. Outdoor work is of little joy these days, because the recent wet weather has produced an invasion of "svidknott" (the Swedish model of no-see-um's). However, a microbiologist hunting biofilms and being presented open fractures in a core doesn't mind (George).
