The National Oceanic and Atmospheric Administration formally advanced the regulatory review of the first-ever commercial deep seabed mining application under U.S. law on Aug. 19, setting a global precedent for the commercial exploitation of the ocean floor.
The application, if approved, would authorize the extraction of polymetallic nodules containing nickel, cobalt, copper and manganese from the seafloor thousands of meters below the surface.
Deep seabed mining targets mineral-rich nodules that have formed over millions of years on the abyssal plain, according to NOAA. The minerals contained in these nodules are essential inputs for battery technology, electronics and clean energy systems.
The application connects to the administration’s broader critical minerals strategy, which seeks to diversify supply away from Chinese-dominated processing. Seabed nodules contain several of the same minerals targeted by the Department of Energy’s domestic supply chain investments and the Department of War’s Brazilian rare-earth initiative.
Environmental advocates have warned of potentially irreversible damage to deep-sea ecosystems that remain poorly understood by science, according to marine research organizations. The deep ocean floor hosts unique biological communities that could be destroyed by mining operations.
NOAA’s review will evaluate the environmental, technical and legal dimensions of the application under the Deep Seabed Hard Mineral Resources Act. The review process includes environmental assessment, public comment and interagency consultation.
The decision carries international implications. The International Seabed Authority, which governs mining in international waters, has not yet finalized its own regulatory framework, meaning U.S. action could influence the global approach to deep-sea resource extraction.
