+++ ICDP: Call for Proposals - Next Chance January 15, 2017 +++ Highlights and Updates Moved to the new ICDP Web Site +++

The first core in the COSC drilling project was retrieved - everybody at the drill site is happy, including the drillers who battled the concrete of last year's cementing of the surface casing. Today the remaining c. 10 m of concrete above the casing shoe of the surface casing was drilled through with the inner casing. Then diamond core-drilling commenced for two core runs (3 m each) before drilling was suspended to pressure-test the surface casing and installations. Image of the day.
