IODP Call for Proposals
Deadline: April 3, 2023

The International Ocean Discovery Program (IODP) explores Earth’s climate history, structure, mantle/crust dynamics, natural hazards, and deep biosphere as described in the IODP Science Plan ( IODP facilitates international and interdisciplinary research on transformative and societally relevant topics using the ocean drilling, coring, and down-hole measurement facilities JOIDES Resolution, Chikyu, and Mission-Specific Platforms (MSP). This notice describes proposals that will be accepted for the April 3, 2023, deadline:

  • JOIDES Resolution: The JOIDES Resolution is scheduled through the end of IODP; therefore, new submissions are not requested. Revisions and addendums to any proposal that is already in the system will be accepted; these proposals could be transferred to a potential future program.
  • Chikyu: New Complementary Project Proposals (CPPs) are encouraged, but other new riser and riserless proposals for the Chikyu may not be submitted at this time. Revisions and addendums to any proposal that is already in the system will
    be accepted.
  • Mission-Specific Platforms: MSP expeditions are planned to operate once a year to drill/core targets that are inaccessible by the other facilities (e.g., shallow water, enclosed seas, ice-covered seas) in any ocean basin until the end of 2024. After that date, MSP expeditions might be implemented in all drilling environments. New and revised MSP proposals for any ocean basin are welcomed.

Investigators are reminded that the interval from the first proposal submission to expedition scheduling is on the order of 4-5 years due to the science and safety review process and required lead time for scheduling, and that adequate site characterization/site survey data are critical for success. Proponents are strongly encouraged to contact the facility’s science operator to discuss platform-specific operational and fiscal constraints before developing proposals:
