General Announcements:
- IODP concluded in 2024 after eleven successful years of enabling the study of the subseafloor. Please visit the Expedition Schedule to learn more about IODP's past expeditions, and the Planning Updates page for information about subsequent scientific ocean drilling programs. Cores and samples may still be requested from the IODP Core Repositories.
- The National Academies of Sciences DSOS committee has released their interim report "Progress and Priorities in Ocean Drilling: In Search of Earth's Past and Future." Download the report.

The International Ocean Discovery Program (IODP) was an international marine research collaboration that explores Earth's history and dynamics using ocean-going research platforms to recover data recorded in seafloor sediments and rocks and to monitor subseafloor environments. IODP depended on facilities funded by three platform providers with financial contributions from five additional partner agencies. Together, these entities represented twenty-one nations whose scientists were selected to staff IODP research expeditions conducted throughout the world's oceans. Scientist activities were managed by the IODP Program Member Offices.
SCIENCE PLAN 2013-2023
IODP expeditions were developed from hypothesis-driven science proposals aligned with the program's Science Plan Illuminating Earth's Past, Present, and Future and were carried out in accordance with the program's Principles of Scientific Investigation. The science plan identifies 14 challenge questions in the four areas of climate change, deep life, planetary dynamics, and geohazards.
