IODP is funded by a number of entities acting as international partners:

	The U.S. National Science Foundation (NSF) and Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT) are Lead Agencies.
	The European Consortium for Ocean Research Drilling (ECORD) is a Contributing Member.
	The People's Republic of China Ministry of Science and Technology (MOST) is an Associate Member.
	Interim Asian Consortium, represented by the Korea Institute of Geoscience and Mineral Resources (KIGAM), is an Associate Member.
	Australia-New Zealand IODP Consortium (ANZIC) is an Associate Member.
	India, Ministry of Earth Science (MoES) is an Associate Member.

The Ocean Drilling Program office at NSF (part of the Marine Geosciences section of the Division of Ocean Sciences, within the Directorate for Geosciences) is responsible for administering commingled funds directed towards the science operating costs (SOCs) of all IODP operations. These commingled funds come from the international partners as part of their membership fees used for the conduct of IODP science. Platform operating costs (POCs) are the responsibility of the agency supplying the platform capability. The IODP Council provides governmental oversight for all IODP activity.
