— The full extent of deep-sea ecology remains relatively poorly understood. (Photo by Alex Rose) Dr Kirsten Thompson, a population biologist at the University of Exeter and an author of the study on the potential impacts of deep-sea mining, is aware of these risks, and the challenges facing mining companies in the future.
The nascent industry of deep-sea mining threatens the health, and perhaps the very existence, of deep ocean communities. It would destroy the physical structures of the seafloor and the ecosystems they house, kick up sediment plumes that smother organisms, alter ocean chemistry across many kilometers, and create noise pollution in the …
— The deep-sea mining vehicle, a pivotal piece of equipment in deep-sea mining operations, is a primary focus of research within the mining system. Reshma et al. (2019) performed a remote-controlled sea tracking test at a depth of 5462 m in the Central Indian Ocean Basin (CIOB) to ensure the maneuverability of the crawler mining vehicle.
— Different mining technologies are deployed to suit different ground conditions. These include an airlift-drill technology, which uses a 6.8m-diameter drill bit working in overlapping circles on the sea floor, and a crawler, which uses a 280-tonne track-mounted crawler to dredge the sea floor.
