Ocean science drilling explorations with D/V Chikyu: frontier and challenging

Many international ocean science drilling programs (e.g. DSDP, ODP, IODP) have been conducted in the oceans all over the world for more than fifty years. A new phase of IODP (International Ocean Discovery Program) with three drilling platforms: the drilling vessel “JOIDES Resolution” by the US, the...
