NanTroSEIZE Deep Riser Drilling: Nankai Seismogenic/Slow Slip Megathrust
(Plate Boundary Deep Riser 4)
7 October 2018 – 21 March 2019
Science Staffing Windows: Please see “call for application” tab.
The main expedition goal 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. This expedition will be the culmination of 10 years of IODP NanTroSEIZE deep drilling efforts to reach the plate interface fault system at seismogenic / slow slip depths.
IODP Expedition 358 drilling at Site C0002F/N/P 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 2 determining the nature of the prominent seismic reflector. Sampling and characterization of rock lithology, chemical and physical properties, structure, and in situ stress & pore pressure conditions of the lower wedge, immediate hanging wall, fault zone and upper footwall are the primary objectives. At the end of this expedition, the borehole will be cased to greater depth and left in a suspended state for possible future re-entry and installation of long-term monitoring instrumentation. Please read the Expedition 358 mini-Prospectus (see PMO announcement for link) for further details.

Science Window Selection
This Expedition is planned for more than five months at sea and thus it will not be staffed as a standard IODP expedition. We solicit applicants for the scientific party who can 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”. Members of the scientific party will be asked to maintain flexible schedules to accommodate this need. All scientific party members will also be expected to participate in a final analysis and sampling meeting at the end of the whole expedition, likely for several weeks in March or April 2019.
Check all time windows below for which you would be available for shipboard participation. Dates are approximate, based on estimated start and end dates.
- 19 Nov – 29 Dec, 2018 (logging-while-drilling operations)
- 6 Dec 2018 – 15 Jan 2019 (logging-while-drilling operations)
- 22 Dec 2018 – 2 Feb 2019 (logging-while-drilling operations)
- 8 Jan – 15 Feb, 2019 (coring operations)
- 15 Jan – 27 Feb, 2019 (logging-while-drilling operations)
- 25 Jan – 5 Mar, 2019 (coring operations)
Preferred Science field
Scientists with interest and expertise in:
- fault zone structure and mechanics
- accretionary complex geology and evolution
- physical and hydrogeological properties
- diagenetic/metamorphic processes and effects
- rock magnetism
- core-log-seismic integration (CLSI)
Because of the nature of the drilling operation and need for near-real time analysis, expertise in the use of 4 drill cuttings, mud gas, and modern well logging to address sedimentary petrology, structure, physical properties and geomechanics are all especially useful.
