France possesses the world’s second-largest exclusive economic zone — 11.03 million square kilometers of ocean territory spanning every inhabited ocean basin on Earth. Greater than the US EEZ, larger than the Australian EEZ, France’s maritime domain is simultaneously one of its greatest strategic assets and one of its most underexploited resources. Approximately 95% of France’s EEZ seafloor has never been systematically mapped, let alone explored for mineral resources, biological diversity, or energy potential.
France 2030 treats this vast oceanic inheritance as a strategic frontier. The plan commits approximately €300 million directly to ocean research, deep-sea exploration, and marine technology development, with additional indirect funding through the food and agriculture allocation (for aquaculture and marine biotech) and the industrial decarbonization allocation (for ocean energy). The vision is not primarily extractive — France has adopted some of the world’s strongest legal protections against deep-sea mining in its own waters — but rather scientific, technological, and selective in economic opportunity.
France’s Ocean Geography: The Strategic Context
No other country in the world possesses an Exclusive Economic Zone as geographically diverse as France’s. From the Arctic-adjacent waters south of Saint-Pierre-et-Miquelon off the coast of Newfoundland, to the tropical Pacific of French Polynesia and New Caledonia, to the sub-Antarctic Kerguelen Islands, to the tropical Caribbean of Martinique and Guadeloupe, France’s EEZ spans all climate zones and ocean systems.
The geographic breakdown: approximately 37% of France’s EEZ lies in the Pacific Ocean, primarily around French Polynesia (5.03 million km²) and New Caledonia (1.74 million km²). Approximately 25% lies in the Indian Ocean, including the Scattered Islands, Kerguelen, Crozet, and Reunion-Mayotte zones. Approximately 20% lies in the Atlantic, with French Guiana, Saint Martin/Barthelemy, and the Antilles providing tropical Atlantic sovereignty. The remaining shares are in the Southern Ocean and tiny Atlantic islands.
This geographic diversity translates into oceanographic diversity: France’s EEZ encompasses some of the world’s most productive fisheries (in the Antarctic and sub-Antarctic), some of the world’s most mineral-rich deep-sea zones (the Pacific Manganese nodule fields), some of the world’s most biodiverse coral reef systems (French Polynesia, New Caledonia’s lagoon — a UNESCO World Heritage site), and some of the world’s deepest seafloor trenches.

IFREMER: France’s Ocean Science Institution
IFREMER — Institut Français de Recherche pour l’Exploitation de la Mer — is the institutional heart of France’s ocean science and technology system. Founded in 1984 as a merger of CNEXO (ocean exploration) and ISTPM (fisheries science), IFREMER has grown into one of the world’s five most capable ocean research institutions, alongside the US NOAA, Germany’s GEOMAR, the UK’s NERC, and Japan’s JAMSTEC.
IFREMER’s primary research campus is in Brest (Brittany) — France’s major Atlantic naval and scientific port. Secondary campuses operate at Issy-les-Moulineaux (near Paris, for administrative and remote sensing work), Nantes, Toulon (Mediterranean operations), La Réunion, and stations in French Polynesia. IFREMER employs approximately 1,500 permanent researchers, engineers, and technicians, with several hundred additional PhD students and postdoctoral researchers at any time.
Key assets: the Nautile deep-sea submersible (operating to 6,000m depth), the Pourquoi pas? and Atalante oceanographic research vessels, a fleet of autonomous underwater vehicles (AUVs), and one of Europe’s most advanced ocean data infrastructure systems.
Under France 2030, IFREMER received investment in AUV fleet modernization, new deep-sea instrumentation, and digital infrastructure for ocean data management. IFREMER also coordinates France’s participation in the international EMSO (European Multidisciplinary Seafloor and Water Column Observatory) network — a permanent ocean monitoring infrastructure connecting sensors across European seafloors.
France’s Position on Deep-Sea Mining: Precautionary Leadership
France has adopted a globally distinctive position on deep-sea mining. In 2021, France enacted a law (the loi Climat et Résilience) that explicitly prohibits exploration for and extraction of mineral resources from the seabed within France’s metropolitan territorial waters and EEZ — making France the first country to formally ban deep-sea mining in its own EEZ by law rather than simply by policy inaction.
This legislative decision reflects the influence of France’s marine science community, led by IFREMER, which has documented the extraordinary biodiversity of deep-sea ecosystems and argued that polymetallic nodule fields, cobalt-rich crusts, and hydrothermal vent mineral deposits are ecosystems of extraordinary complexity that would be permanently destroyed by mining.
However, France’s position is more nuanced than a blanket moratorium. France retains exploration licenses in the international seabed of the Clarion-Clipperton Zone (CCZ) in the Pacific — areas beyond any national EEZ — held through IFREMER’s exploration contracts with the International Seabed Authority (ISA). France’s stated position: support for the strongest possible environmental regulations at the ISA before any commercial extraction begins, but participation in research and exploration to understand the resources and their extraction feasibility.
France 2030 funds deep-sea research explicitly oriented toward environmental impact assessment — understanding the recovery time of deep-sea ecosystems after disturbance, the connectivity between deep-sea communities, and the development of technologies that could eventually allow more selective and less damaging extraction if and when a strong regulatory framework exists.
Ocean Energy: France’s Atlantic and Channel Renewable Frontier
France’s ocean energy ambitions extend beyond the offshore wind programs prominent in the energy sector. ADEME’s ocean energy program, partially funded through France 2030, supports tidal stream, wave energy, and floating offshore wind development.
The Paimpol-Bréhat experimental tidal stream site off the Brittany coast is Europe’s most advanced grid-connected tidal energy demonstration. Sabella, the Quimper-based tidal turbine company, has operated a 1MW turbine at Ushant since 2015 and is developing a commercial tidal array project. France 2030 supports the commercialization pathway for French tidal technology companies.
Floating offshore wind — a technology enabling offshore wind turbines in water depths above 50m, expanding the accessible offshore wind resource dramatically — is France’s most significant ocean energy development area. Several commercial floating wind zone designations are planned for the Mediterranean and Atlantic coasts. France 2030 supports floating wind technology development through both the renewable energy allocation and the marine technology R&D budget.
Marine Biotechnology: The Blue Economy Opportunity
France’s extraordinary marine biodiversity — encompassing tropical reef systems, temperate Atlantic coastal ecosystems, sub-Antarctic marine systems, and deep-sea hydrothermal vent communities — provides a remarkable natural library for bioactive compound discovery. Marine organisms have evolved biochemistries radically different from terrestrial life, producing compounds with pharmaceutical, cosmetic, agricultural, and industrial potential.
France 2030 funds marine biotechnology through a dedicated blue bioeconomy program managed jointly by IFREMER and Bpifrance. Key focus areas: marine-derived pharmaceutical leads (anti-cancer, anti-infective, neurological compounds from deep-sea organisms), cosmetic actives from marine algae (the luxury cosmetics industry is a major French sector with strong marine ingredient interest), bioplastics from marine biomass, and sustainable aquaculture feed from marine microorganisms.
French companies including Olmix (seaweed-based agricultural and animal nutrition products, based in Brittany) and several biotechnology startups spun out of IFREMER and the CNRS Roscoff Marine Station are active in commercial marine biotechnology. France 2030 funding through Bpifrance’s deep tech investment program has reached several marine biotech startups.
Strategic Significance: Sovereignty Through Ocean Knowledge
France’s investment in ocean science and technology under France 2030 is ultimately a sovereignty investment. Countries that understand their oceans — their resources, risks, and opportunities — possess strategic advantages over those that do not. As climate change transforms ocean ecosystems, as deep-sea mineral resources become increasingly relevant to energy transition supply chains, and as ocean shipping and undersea cables become ever more critical to global economic infrastructure, France’s 11-million-square-kilometer maritime domain becomes proportionally more valuable.
The France 2030 ocean investment is modest in absolute terms compared to the semiconductor, hydrogen, or electric vehicle allocations. But the leverage effect is exceptional: IFREMER’s €80 million France 2030 infrastructure investment enables scientific work that generates vastly more knowledge, technology, and long-term strategic value than its raw euro figure suggests.
