One of the key objectives of the IODP is to understand the initiation and evolution of oceanic arcs. This is where oceanic plates converge and one dives beneath another, producing strings of volcanic islands above the subduction zone. This is how continental crust making begins. The Izu-Bonin-Mariana (IBM) arc, off the southern coast of Japan, has been a target for researching this process for many years.

Expedition 351 (IBM Arc Origins) will sail from Yokohama, Japan on May 30, 2014, with co-chief scientists Richard Arculus (Australian National University) and Osamu Ishizuka (Geological Survey of Japan) leading the science team . This expedition will drill even further to the west then in Expedition 350, in the Amami Sankaku Basin, to understand what the oceanic crust looked like before IBM subduction began in the middle Eocene.

What happens at the edges of large oceanic plates when subduction begins?
