UMC 2023 Focus

Making It Happen:
Advances in Marine Minerals Development

Since 1970 the Underwater Minerals Conference (UMC, originally the Underwater Mining Institute) has provided a nexus linking academic, industrial, and governmental professionals working in all disciplines related to marine minerals, mining and exploration.  In doing so the UMC has built a unique, international network of participants for over half a century. The Conference is more than an annual forum; it has, through the years, fostered cooperation, assistance and understanding among those who compose the marine minerals community.  It has been the catalyst for forming the International Marine Minerals Society (IMMS, incorporated in 1987) and for many joint ventures, business deals, research grants, service contracts and student stipends.  




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.

Rotterdam is a funky port city that prides itself on its unique architecture, cool art, amazing food, and massive harbor. The city is one of the most multicultural in the Netherlands and hosts an array of festivals and concerts throughout the year.

This 4-star design hotel is located in a unique spot in the center of Rotterdam, at the foot of the Erasmus bridge and has a panoramic view of the Maas river and the city. The main tourist attractions, shops and nightlife are within walking distance.

Rates are specially discounted for UMC guests starting at €155 for a single room.

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
