Design, Manufacture, and Operation of a Core Barrel for the Iceland Deep Drilling Project (IDDP)
The science program of the Iceland Deep Drilling Project (IDDP) requires as much core as possible in the transition zone to supercritical and inside the supercritical zone (>374°C), in the depth interval 2400–4500 m. The spot coring system selected has a 7 ¼" (184.15 mm) OD at 10 m length an...
