DRILLING FOR PAST ANTARCTIC CLIMATE - THEN AND NOW

Talks in the first part of the evening are from scientists involved in the first Antarctic ocean drilling by the GLOMAR Challenger, which visited the same port 45 years ago. In the second part IODP 374 co-chief scientists present the context and initial results for the just completed Expedition.
