The Crustal Ocean Biosphere Research Accelerator (COBRA) Will Inform Decision Making for Deep-Sea Mining and Subseafloor Carbon Sequestration

Water-rock reactions in lithospheric oceanic crust at and below the seafloor control the cycle of many chemicals in the ocean and enable life that supports the base of deep-sea food webs. The emergent industries of deep-sea mining and subseafloor carbon sequestration from injected carbon dioxide underscores the urgent need for understanding this crustal ocean biosphere. Here, we will highlight plans for the new Crustal Ocean Biosphere Research Accelerator (COBRA) network-of-networks project to bring together diverse stakeholders to coordinate efforts to catalyze new knowledge and inform decision making. We will also highlight efforts to democratize equitable access to deep-sea research infrastructure to empower diverse communities to lead inclusive research efforts. COBRA is an open network, and we welcome anyone who is interested in these and related topics.
