New Zealand participates in the International Ocean Discovery Program in partnership with Australia. The Australian and New Zealand IODP Consortium (ANZIC) is funded by the Australian Government through the Australian Research Council’s LIEF funding scheme and a consortium of Australian and New Zealand universities and government agencies. New Zealand’s participation is coordinated by GNS Science. National membership includes GNS Science, NIWA, University of Auckland, University of Otago and Victoria University of Wellington.

The International Ocean Discovery Program (IODP) is 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 depends on facilities funded by three platform providers (US, Japan and a European Consortium) with financial contributions from five additional partner agencies, including ANZIC. Together, these entities represent 23 nations whose scientists are selected to staff IODP research expeditions conducted throughout the world's oceans. IODP is celebrating 50 years of operations in 2018.

This video showcases the research done under the program. And here you can find out how the science behind IODP works.

The program operates three scientific drilling platforms: the US-based JOIDES Resolution, a riserless drilling vessel and the main workhorse of the program; the Japan-based Chikyu, a riser vessel capable of drilling in areas where hydrocarbons could be encountered; and the European-based mission specific platforms, which are used to drill areas where the others vessels cannot (e.g., Arctic Ocean, shallow water). 

IODP is the largest international geoscience program in the world, with 23 member countries. The program's mission is to explore Earth's history and structure as recorded in seafloor sediments and rocks. The program themes and objectives are outlined in the IODP Science Plan: Illuminating Earth’s Past, Present and Future. The four science themes are:

  • Climate and Ocean Change: Reading the Past, Informing the Future
  • Biosphere Frontiers: Deep Life and Environmental Forcing of Evolution
  • Earth Connections: Deep Processes and Their Impact on Earth’s Surface Environment
  • Earth in Motion: Processes and Hazards on Human Time Scales

By clicking on the links in the left-hand box you can read more about the structure of the programme at an international level, the way New Zealand participates in IODP, stories of New Zealand scientists who took part in recent expeditions, and how to apply to participate on an expedition.
