Scientific Ocean Drilling and Land-to-Sea Proposal Deadline

We would like to remind the IODP3 community to ensure that all proposals are completed and submitted by midnight GMT on 1^st July 2025 via the IODP3 Gateway.

The IODP3 Gateway now accepts all proposal types – including all forms of Scientific Ocean Drilling proposals, and all forms of Land-to-Sea proposals. Submission guidelines can be found on our website here. These include step-by-step instructions and screenshots to help you navigate the Gateway system.

Any proposals submitted after the deadline will be reviewed in the next evaluation cycle. Please note – there is only one annual deadline for Land-to-Sea proposals, so any Land-to-Sea submissions received after 1st July will not be assessed until July 2026!

Our next SPARCs deadline is 31st January 2026, however SPARC proposals are welcomed at any time, ready to be assessed in February 2026.

For more information about IODP3 proposals please see our webpage here.

For any questions about proposal submission processes, please contact us at proposals@iodp3.org.

Any questions about registering for an IODP3 Gateway account should be sent to enquiries@iodp3.org.

Best of luck with your submissions!
