Underwater Minerals Conference 
The World's Largest Gathering of Ocean Mineral Stakeholders

The Underwater Minerals Conference (UMC) is an annual international forum, with representatives from over 25 countries that since 1970 has brought the marine minerals community together. UMC is the world’s largest gathering of ocean mineral stakeholders, including government, academic, and commercial sector 

professionals. Topics considered for the conference include:


  • Geological and biological studies of marine minerals deposits and their      associated biological communities.

  • Regulatory considerations related to mineral resource and environmental impact assessment.

  • Technological considerations related to scientific survey objectives and commercial recovery objectives.

  • General policy considerations related to the long-term development of these resources.

  • Other relevant topics.

UMC 2024 - The 52nd Underwater Minerals Conference is presented by the International Marine Minerals Society (IMMS) in partnership with the government of the Cook Islands. This year's Technical Program Chair is Dr. John Wiltshire, president of IMMS.

UMC 2024 Focus

Going Deep:

Getting the Science Right for Informed Decisions

As manganese nodule mining grows even closer to fruition, it becomes ever more important to have regulations based on prudent and well-grounded science. Deep-sea mining raises concerns. Some of these are well-founded and others are frivolous. For miners, it is critical to substantially address real environmental issues and show how they can be managed or mitigated. At the same time, it is prudent not to waste funds on irrelevant conjecture. At UMC, we will attempt to highlight new findings and show where accurate material can be fed into regulations to smooth the path forward and tamp down needless controversy.

UMC provides a platform for researchers, business leaders, governing authorities, and other stakeholder to share about different national policies on underwater minerals exploration, research findings on different regions of the ocean and the development of new technologies that can help better manage operations underwater.

UMC 2024 will be held at the Cook Islands National Auditorium, This facility has over the last 30 years been used for an array of events, from constitution celebrations to international conferences like Pacific Leaders Forums .

Rarotonga is the largest and most populous of the Cook Islands. The island is volcanic, with an area of 67.39 km2, and is home to almost 75% of the country's population, with 10,898 of a total population of 15,040. The Cook Islands' Parliament buildings and international airport are on Rarotonga. It is a very popular tourist destination with many resorts, hotels and restaurants. It has beautiful beaches, and is compact and easy to get around. The island's coast is made up of an upraised coral reef, with a ring of fertile volcanic soil between the mountains and the coast. Avarua, on the north coast, is the capital of the Cook Islands.

UMC happens once a year and provides an indispensable source of information and exchange of ideas between the ocean mining industry, the government institutions, the non-profit organizations and academia. It has a scientific focus where the active marine mining players can learn more about the advances in ocean minerals science. The Underwater Mining Conference is the World’s largest gathering of Ocean Minerals Stakeholders.

This year of 2024 UMC will be special, for the first time located in a country filled with marine minerals and with marine mineral exploration rules already in place.
