The Global Deep Sea Consultation

In October 2023, French President Emmanuel Macron requested an international scientific consultation to synthesize the "scientific evidence concerning the serious risks that the international community would take by allowing the exploitation of the deep sea."

In response, Bruno David, President of the Muséum national d'histoire naturelle from 2015 to 2023, and Towards IPOS created an international scientific committee to compile expert advice and recommendations from deep-sea scientists and a large range of knowledge holders from around the globe. Our committee is co-chaired by Elva Escobar-Briones (Mexico) & Ricardo Serrão Santos (Portugal) and coordinated by Kelsey Archer Barnhill (United States).

This consultation worked on two main outputs: a brief position statement backed with signatures, and an expert question and answer booklet.

Q&A

Q&A booklet featuring 32 pressing questions on deep-sea mining, answered by international experts to inform policymakers:

Scientific Proclamation

Scientific Proclamation, a co-created position statement on deep-sea mining backed with the signatures of all 17 Scientific Committee Members and translated into French and Spanish:

Our scientific committee members were selected to represent diverse genders and geographical backgrounds, providing expertise in both natural and social sciences within the fields of deep-sea research, ocean governance, mineral resources, environmental economics, ecosystem management, and oceanography.

Our international and transdisciplinary approach aims to deliver inclusive and comprehensive insights to bridge the science-policy interface within the deep-sea mining debate.

Through compiling expert advice, insight, and recommendations from experts across disciplines and geographies, this Towards IPOS pilot project produces scientifically credible, contextually relevant, and globally resonant recommendations.

These outputs were launched on the 31st of March 2025 at the SOS Ocean event in Paris, France and will be featured at the One Ocean Science Congress (3-6 June 2025) and UN Ocean Conference (28 May - 13 June 2025).

Reflections and Next Steps

Towards IPOS is honoured to have been part of this important international scientific consultation on deep-sea mining (DSM). This joint venture, carried out in partnership with Bruno David, was an opportunity to explore best practices for delivering rigorous science to inform policy, providing a working pilot study while IPOS was shaping its services and processes.
