Expedition 351 (IBM Arc Origins) sailed from Yokohama, Japan the week of 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 is drilling 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.

July 30, 2014 - September 29, 2014

This will not only give insight into how subduction zones form, but also how the magma generated from this process eventually becomes the crust of an island arc and then a continent.
