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.


Upcoming expeditions
July 30, 2014 - September 29, 2014

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

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.
