Current Expeditions

Expedition 365: NanTroSEIZE Stage 3: Shallow Megasplay Long-Term Borehole Monitoring System is recovering the GeniusPlug instrumentation package from IODP site C0010 offshore Japan, and will deploy a permanent long-term borehole monitoring system after deepening the hole to over 650 meters below seafloor. Watch video - Part 2

NOTICE: As part of contingency operations made possible by completion of primary objectives well ahead of schedule, IODP Expedition 365 will drill and collect core at IODP Site C0010 from ~300-600 meters below seafloor. A description of this site is available at: The core will be analyzed and described at a post-expedition sampling party in summer, 2016.

We currently invite sample and data requests for this core (details for requesting samples and datas can be found at: Requests are due on May 20, 2016.

Expedition 364: Chicxulub Impact Crater in collaboration with the International Continental Drilling Program is exploring the impact crater offshore Yucatan, Mexico, that has been linked to the asteroid impact leading to the extinction of the dinosaurs and most other Cretaceous life forms. Download flyer
