The big challenge for deep-sea mining BBC
In 2021, the Pacific nation of Nauru in Micronesia took one big step closer to deep-sea mining, announcing its intention to begin commercial exploitation of the seabed. That triggered an obscureThe U.N. Convention on the Law of the Sea (UNCLOS) mandates that states govern deep-sea mining on seabed within their national jurisdiction. But roughly 60 percent of the ocean bottom is located beyond the jurisdiction of individual states.

Deep seabed mining: Frontiers in engineering geology and
Ocean mining activities have been ongoing for nearly 70 years, making great contributions to industrialization. Given the increasing demand for energy, along with the restructuring of the energy supply catalyzed by efforts to achieve a low-carbon economy, deep seabed mining will play an important role in addressing energy- and resource Deep-sea mining is the process of exploring the deep seabed and retrieving minerals like cobalt and manganese (used in things like rechargeable batteries, smartphones, and steel), as well as gold, nickel, and rare earth elements.

Combustible Ice Sets off Global Battle for Seabed Resources
Deep-sea treasure “combustible ice” a low-carbon energy source. In the context of the increasing strain on global land resources, more and more countries are turning their attention to the oceans. Combustible ice, which has been hailed as the most commercially promising strategic resource of the 21st century, has entered the spotlight.The technology used for deep-seabed mining is different for different resources. But all the technologies follow the standard procedure of violating the sea floor, the water above and a massive reshuffling of habitats.

Deep Sea Mining SpringerLink
Deep sea mining is defined as the process of seabed mineral excavation, transmission, lifting from the deep to the surface, and extracting valuable metal elements or products from the minerals. The definition of deep seabed is usually distinct in different disciplines. Generally, the depth of deep seabed mining is referred to much deeper thanSuch concerns are unlikely to arise with seabed mining, as this is a capital-intensive and technology-dependent undertaking where artisanal methods are not possible. Seabed mining may be a way to diversify critical minerals supply chains and break China's stranglehold on supplies of some of the world's most important natural Is Seabed Mining an Opportunity to Break China's Stranglehold

Geographies of deep sea mining: A critical review ScienceDirect
The seabed's potential as a resource frontier has already been cartographically extended to an extent not previously seen. 2 UNCLOS, itself catalysed by the 1945 Truman Proclamation, served to extend seawards the territory of the states by 200 nautical miles by establishing Exclusive Economic Zones all over the globe.

The deep-sea mining dilemma C&EN Global Enterprise ACS
The seabed is a potentially promising source of critical minerals that are in heavy demand for clean energy technologies. But retrieving those resources comes with long-term environmental consequences. Proponents argue that extracting minerals from the deep sea has fewer impacts on nature and human lives than land-based mining does. A Extracting those resources from the seabed is less harmful to the environment than mining above ground, according to Oliver Gunasekara, CEO of the U.S.-based mining company Impossible Metals, which is working on a robot that uses artificial intelligence to harvest nodules without disturbing undersea life.The uncharted waters of deep-sea mining POLITICO

The Future of Mining: The Exploitation of Marine Geological Resources
Under the auspices of the International Seabed Authority (ISA), projects exploring seabed mineral resources in the seabed and ocean floor and subsoil thereof, beyond the limits of national jurisdiction, named ‘the Area’, began in 2001. From then to the present, more and more countries have become involved in such projects.Rising demand for minerals and metals, including for use in the technology sector, has led to a resurgence of interest in exploration of mineral resources located on the seabed.
