Call for Drilling and LEAP Proposals
Deadline: April 1, 2024
The International Ocean Discovery Program (IODP) explores Earth’s climate history, structure,mantle/crust dynamics, natural hazards, and deep biosphere. IODP facilitates international andinterdisciplinary research on transformative and societally relevant topics using the ocean drilling,coring, and down-hole measurement facilities JOIDES Resolution, Chikyu, and Mission-Specific
Platforms (MSPs), as well as through the use of scientific ocean drilling legacy assets. This noticedescribes scientific ocean drilling and LEAP proposals that will be accepted with a deadline ofApril 1, 2024. Please visit iodp.org for more information and proposal guidelines. The proposal
system will open for submissions on February 15, 2024.
Drilling Proposals
The International Ocean Discovery Program uses the program's drilling platforms for hypothesisdriven science in line with the themes and challenges outlined in the IODP Science Plan
(http://www.iodp.org/science-plan). Proposals frequently involve collaborations between
international researchers from the multiple geoscience disciplines, and the lead proponent neednot be from an IODP member country.
Investigators are reminded that the drilling platforms are fully scheduled through the end of thecurrent program, but processes are being considered for how proposals could transition to futurescientific ocean drilling programs. Proponents are strongly encouraged to contact the facility’s
science operator to discuss platform-specific operational and fiscal constraints before developing
proposals (http://www.iodp.org/expeditions/science-operators).
•Mission-Specific Platforms: MSP expeditions typically are used to drill/core targets thatare inaccessible by the other facilities (e.g., shallow water, enclosed seas, ice-coveredseas) 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 oceanbasin and any scientific target are welcomed.

•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.

•JOIDES Resolution: The JOIDES Resolution is scheduled through the end of IODP;
therefore, proposals may not be submitted for this platform.

LEAP Proposals
Ocean Drilling Legacy Assets Projects (LEAPs) are a new type of project for international andinterdisciplinary collaborations under the umbrella of the scientific ocean drilling programs. They
are standalone research endeavors that: (1) address at least one aspect of the 2050 Science
Framework, and (2) have objectives that maximize the return on the legacy assets of current andpast scientific ocean drilling programs without new drilling. Examples of legacy assets are cores,

samples, data, open boreholes, and downhole observatories from current and past scientificocean drilling programs.
Avenues of LEAP research could include, for example, the production of new data from samples,
integration of data across multiple expeditions and/or multiple boreholes, incorporation of legacy
borehole data with new data, application of a new method or technology that was not available
when the legacy assets were collected, or measurements in legacy drillholes to address new
problems in innovative and creative ways.
LEAPs do not replace other research mechanisms (e.g., individual proposals to funding agencies
for sample requests or data analysis); instead, they are intended to provide a new avenue tofacilitate collaboration at scales larger than conventional single or multi-proponent research
projects.
The definition for LEAPs is deliberately broad to provide flexibility for new approaches,
integrations, and technology uses that foster coordinated multidisciplinary and international
research efforts. LEAPs also provide an opportunity through which researchers can increase thevisibility of their research and results.
Informational Webinar Dates:• February 15 at 10:00 EDT (February 15 at 15:00 UTC)• February 15 at 22:00 EDT (February 16 at 03:00 UTC)For more information on LEAPs and to register for the webinars, please visit:https://www.iodp.org/call-for-leap-proposals
