Program Update: International Ocean Discovery Program – July 2014
This month, the JOIDES Resolution embarked on Expedition 352 (IBM Forearc), the final in a series of three expeditions focused on the Izu-Bonin-Mariana (IBM) oceanic arc, where the Pacific Plate subducts beneath the Philippine Sea Plate. Led by co-chief scientists Julian Pearce (Cardiff University, UK) and Mark Reagan (University of Iowa), Expedition 352 will drill just to the west of the Mariana Trench, into rocks that directly overlie the subduction zone. The overall goal is to understand whether and how subduction can contribute to the formation of ophiolites – large structures formed from layers of oceanic crust.
IODP hosted a public panel discussion in Washington, DC, on July 1. The event, titled “An Evening at the Bottom of the Ocean: Meet the Scientists of the International Ocean Discovery Program,” featured Dr. John Jaeger and several other members of the US Advisory Committee for Scientific Ocean Drilling. The panel discussed the seminal scientific achievements of IODP and its predecessor programs, their own experiences exploring the Earth beneath the sea, and what makes them excited to be a part of it all. The discussion was well received by those who attended.
