Global Seabed Mineral Resources
The Global Marine Mineral Resources project studies deep ocean minerals that occur within the U.S. Exclusive Economic Zone and areas beyond national jurisdictions. Our research concerns the setting, genesis, and metal enrichment processes of mineral occurrences, the relationship between marine minerals and deep-sea biota, and the potential geochemical footprint of any seafloor mining. We aim to...
