The dangers of deep-sea mining

 · Researchers from the University of Exeter, UK, claim that deep-sea mining in international waters (which could start in as little as two years) could cause irreversible damage to aquatic ecosystems and affect many different marine species, according to a study published in the journal Frontiers in Marine Science (1). The deep-sea – areas below 200m – covers over half of our planet''s surface.

Seabed Mining

Seabed Mining () is a growing industrial field that involves extracting submerged minerals and deposits from the sea floor. To date, mining for sand, tin and diamonds has been generally limited to shallow coastal waters. Seabed Mining () should be distinguish from Deep Sea Mining (DSM) that occurs at a depth of 200 meters and greater.

Seafloor Mining

Timothy Shank is a deep-sea biologist, Associate Scientist in the Biology Department, and former Director of the Ocean Exploration Institute at the Woods Hole Oceanographic Institution. He is known for his research on the ecology and evolution of fauna in deep-ocean hydrothermal, seamount, canyon and deep trench systems.

Understanding the impact of deep-sea mining | MIT News ...

 · Impact on deep-sea organisms. Life on the ocean floor moves at a glacial pace. Sediment accumulates at a rate of 1 millimeter every millennium. With such a slow rate of growth, areas disturbed by deep-sea mining would be unlikely to recover on a reasonable timescale.

Conflict over the UK''s deep sea mining licences | Mining ...

 · A moratorium on deep sea mining. Indeed, the first deep sea mining test in the Pacific was something of a PR nightmare, with a 25 tonne mining robot lost on the seafloor after its communication cable was severed. While the robot was soon recovered, it has given fodder to the argument that this industry is harmful to marine life.

Opinion: Deep-sea Mining has Time. – DSM Observer

 · Deep-sea mining will be the model for the next generation of extractive industries beyond national boundaries. Unlike the vast majority of green revolution technologies and policies necessary to avert the worst outcomes of climate change, deep-sea mining is in the enviable position of a long lead time to get the science, the regulations, the ...

New depths: where is the value in mining the deep sea ...

2  · Polymetallic nodules rich with Copper, Nickel and Manganese strewn across the ocean bed could play an important role in powering the energy transition, as these metals are used in solar panels, wind turbines and electric vehicle batteries.

Commercial deep-sea mining is presently in an exploratory phase, but is certain to occur because of the expected need for minerals that are rapidly being depleted from terrestrial sources. The deep sea is a rich source of these minerals, which can be found on the seafloor in the form of polymetallic nodules, polymetallic sulphides, and cobalt-rich ferromanganese (Fe-Mn) crusts.

Deep Sea Mining

Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost.
