Take the JR Community Survey! Read this important announcement about planning for the future of the JOIDES Resolution and take the survey by March 31. We hope to hear from all who have, or plan to, sail on the JR or used data acquired during her expeditions.
Attending EGU? The Joint IODP-ICDP Town Hall Meeting is Tuesday April 25 (19:00-20:00) in Room G2. Session SSP 1.3, Achievements and Perspectives in Scientific Ocean and Continental Drilling, is Thursday April 27 (talks 13:30-17:00, posters 17:30-19:00).
A new white paper on Seagoing Seismic Imaging and Scientific Ocean Drilling based on discussions in the IODP Forum is available.
Read NSF's Dear Colleague Letter on how the JR's Advanced Piston Coring capability will be made available to the U.S. community outside of IODP.
Deadline approaching! Apply to Sail for Brothers Arc Flux (by April 1).
Science Community volunteers sought for JRSO Laboratory Working Groups.
In a pair of expeditions to the South China Sea aboard the JOIDES Resolution, scientists will explore the mechanisms of lithosphere extension during continental breakup by drilling four sites across a 300-km wide zone of highly extended, seaward thinning crust. The expedition will core through thick sedimentary sections to look for serpentinized mantle in the underlying continent-ocean-transition basement zone. The presence or absence of serpentinite will support competing models of plate rupture. Study of the sedimentary sections will constrain the timing of rifting, rate of extension, and crustal subsidence that resulted the present-day South China Sea, leading to a new understanding of how marginal basins begin and grow. daily reports
Expedition 366 to the western Pacific Ocean aboard the JOIDES Resolution investigated the geochemistry, tectonics, and biology in an active subduction zone by coring the summits and flanks of serpentinite mud volcanoes on the forearc of the Mariana system, a non-accretionary convergent plate margin. Re-entry cones were installed in cased boreholes at three sites to provide infrastructure for future installation of long-term borehole monitoring systems. The sediment, rock, and fluid samples obtained during this expedition will be used to understand mass transport and geochemical cycling, track the spatio-temporal variability of subduction-related fluids and water-rock interactions, and study how physical properties and dehydration might control seismicity in non-accretionary convergent forearc systems.
