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.
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.
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.
This expedition will address questions about the opening and evolution of the South China Sea and how it affected the paleoceanography of the region.
From Valdez, Alaska to Busan, Korea, follow the JOIDES Resolution as it sets out to collect core samples in the Japan Sea.
Get ready to explore how global climate change, tectonics, and sedimentation are revealed in the Gulf of Alaska!
Hess Deep Plutonic Crust
12 December 2012 to 12 February 2013
Puntarenas, Costa Rica to panama City, Panama
A study of earthquakes in a fascinating spot!
In 1912 the Titanic collided with an iceberg in the frigid waters of the North Atlantic. Now, 100 years later, Expedition 342 strives to discover past climate conditions that led to the Arctic ice that sank the unsinkable.
Expedition 340T will measure rock properties, how they vary with depth, and whether adjacent seawater temperatures change. These data will test hypotheses about how crust forms and evolves at the slow-spreading Mid-Atlantic Ridge.

During Expedition 327 we installed subseafloor observatories in two new holes in oceanic crust, replaced an observatory in an existing hole to facilitate long-term monitoring, recovered and replaced an instrument string deployed in one of the Expedition 301 subseafloor borehole observatories; and completed remedial cementing of another Expedition 301 observatory that is not sealed at the seafloor.
Expedition 327 included an international education and outreach program to develop tools and techniques that facilitate the communication of exciting scientific drilling results to a broad audience, build educational curricula, and create media products that will help achieve critical outreach goals.

On Expedition 317 (November 4 2009 - January 4 2010), the scientists investigated ancient changes in sea level. In other words, how deep was the ocean in the past? The scientists on this expedition were (and are) working to figure out how much of the change in sea level that we see in the rock record is caused by actual rise and fall of sea level (because of glaciers freezing and melting), and how much of it is because rocks got pushed up out of their ocean home.
