CALL: Expedition 358 - NanTroSEIZE Plate Boundary Riser 4 aboard the Chikyu

ECORD is seeking scientists to participate in the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) Project on-board the Drilling Vessel Chikyu (7 October 2018 - 21 March 2019).


The Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) Project comprises multiple expeditions over a multi-year period aimed at sampling and instrumenting the up-dip transition into the subduction seismogenic zone.

The goal of Expedition 358 is to deepen riser hole C0002F/N/P from 3000 mbsf to the primary megathrust fault target at ~5200 mbsf, using logging-while-drilling (LWD), downhole measurements, and drill cuttings analysis extensively, in addition to limited coring intervals. Drilling aims to further deepen this hole to access the subduction plate boundary fault system, testing hypotheses for the mechanics and geological /geochemical evolution of megathrust faults, as well as determining the nature of the prominent seismic reflector. 

The expedition is currently planned to begin on 7 October 2018 and finish on 21 March 2019 (164 days). This expedition is planned for more than five months at sea and therefore will not be staffed in the standard expedition “shipboard scientific party” model. Specifically, for Expedition 358: 

  1. Scientific party members should make themselves available for time windows of 2-3 months’ duration, during which they will likely be asked to board Chikyu for one or more 2 to 4 week “shifts.”
  2. All members of the scientific party will also be expected to participate in a final analysis and sampling meeting at the end of the expedition, anticipated to require several weeks in March or April of 2019.

*Informational Webinar*: To learn more about Exp. 358, attend the web-based seminar on Nov. 29 at 11:00 AM Eastern Time. To participate in the webinar, you need access to the internet and a computer with microphone and speaker capability, or a telephone. To register, click the link here. After registering, you will receive an email response with instructions on how to join the webinar.


Opportunities exist for researchers (including graduate students) to sail on the expedition. Scientists with interest and expertise in: fault zone structure and mechanics, accretionary complex geology and evolution, lithostratigraphy, physical and hydrogeological properties, diagenetic/metamorphic processes and effects, micropaleontology, microbiology, rock magnetism, and core-log-seismic integration in structurally-complex settings are all invited to apply. Because of the nature of the drilling operation and need for near-real time analysis, expertise in the use of drill cuttings, mud gas, and modern well logging to address sedimentary petrology, structure, physical properties and geomechanics are all especially useful.

The application deadline is 4 January 2018.

For more information, please see:
Canadian-based applicants must be NSERC-funded active researchers, or students/fellows working under the direct supervision of such researchers.  Candidates may request support and feedback on their application from the CCOD Coordinator.  All candidates must send their application to at least 1 week before the deadline (before submission to ECORD) for approval by the CCOD Executive Committee.  
Please note that the way in which Canada participates in IODP has recently changed.  Funding for our membership in ECORD is now solely driven by individual researchers and their respective universities, and is guaranteed until December 31, 2017.  Canadian selection for expeditions is contingent upon Canada maintaining active membership.  All applicants should thus contact us to see how they can contribute.
