This month, the JOIDES Resolution embarked on Expedition 350 (IBM Rear Arc), the first 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 Yoshihiko Tamura (JAMSTEC/IFREE) and Cathy Busby (University of California, Santa Barbara), Expedition 350 will examine the rear arc area to the west of the subduction zone. By recovering a complete record of rear-arc volcanism from the present back to its likely inception in early Oligocene or Eocene times, the science team hopes to add to our understanding of the development and chemistry of oceanic crust.

The third JOIDES Resolution Facility Board (JRFB) meeting took place at Ocean Leadership April 23-24. Topics included reports from the Science Support Office, the ECORD Facility Board, and the Chikyu IODP Board; reviews of drilling proposals; scheduling options for FY 2016 expeditions; and further discussion of the Annual Program Plans for both the vessel and the IODP Support Office. The Board also nominated a new chair, Rick Murray (Boston University), who will replace Susan Humphris (Woods Hole Oceanographic Institution) when her term ends in October.
