Risks of deep-sea mining are not fully understood: Here's why that ...
Jul 21, 2022 · The deep sea and its biodiversity play a key role in ecosystem services, such as climate regulation, fisheries production, and elemental cycling. Deep-sea mining, which could seriously and irreversibly harm marine ecosystems and have long-lasting consequences for the health of the Earth, may be given the green light to begin in 2023.

FAQs: Deep-Sea Mining - Woods Hole Oceanographic Institution
Jun 6, 2019 · Deep-sea mining is the proposed extraction of metallic and non-metallic mineral resources from the ocean floor at water depths greater than 200 meters (650 feet). Shallow-water mining for sand, tin, and diamonds already occurs in some locations around the globe.
Seafloor Mining - Woods Hole Oceanographic Institution
Seafloor Mining. Hot, buoyant, mineral-laden fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor “chimneys,” and mineral particles in the fluids venting at the seafloor make the fluids look like ...
With deep-sea mining, do microbes stand a chance?
Mar 16, 2023 · Removing the microbes, which deep-sea mining would inevitably do – either by direct removal or by substantially altering the narrow range of conditions they can survive in – would not be temporary. Given the lack of light, the relatively small influx of nutrients (compared to the surface ocean), the sluggish circulation of currents, and the ...
Deep-sea minerals could meet the demands of battery supply …
Aug 3, 2020 · Deep-sea mining could offer lower financial cost and a lighter carbon footprint than conventional terrestrial sources of these minerals; it also has the potential to significantly harm one of the last natural wildernesses on our plant.

Decision-Making on Deep-Sea Mineral Stewardship: A Supply …
Apr 12, 2022 · Demand for these minerals, such as cobalt and nickel, is forecasted to dramatically increase. But mining would damage seafloor ecology, leading to wider environmental and social effects. This report identifies significant gaps in knowledge, stakeholder participation and consensus that impede sound decision-making on deep-sea mineral stewardship.
Deep-Sea Minerals Dialogue | World Economic Forum
Proponents of deep-sea mining point to its potential benefits, compared with conventional mining. It could relieve pressure to mine virgin sites on land, it may offer less carbon-intensive extraction and it could provide much-needed income for economically vulnerable island nations.On the other hand, scientists have voiced deep concern for the ...
Should deep-sea minerals be part of battery supply chains?
Apr 13, 2022 · Much attention has been given to deep-sea environmental baselines, mining impact and management techniques, and knowledge gaps related to these areas. But without more knowledge in the effects of increased availability of critical metals, even with an increased understanding of environmental effects, decision-makers would still not be able to ...
