New Deep-Sea Evolutionary Branch Found as Mining Push Advances

Scientists identify 24 new deep-sea species and a new superfamily in the Clarion Clipperton Zone, underscoring how a regulatory gap and NOAA’s fast-tracked mining permits could threaten unknown life as commercial extraction expands; naming these species provides them a “passport for living” in scientific discourse, but most CCZ species remain unnamed, complicating policy decisions amid observed environmental costs from early mining tests.

Experts challenge deep-sea 'dark oxygen' claim, call for retracting 2024 study

A 2024 study claimed that deep-sea polymetallic nodules could generate oxygen in total darkness via seawater electrolysis, but a December 2025 opinion article from marine scientists and electrochemists argues the results are flawed and likely artifacts, citing improper chamber ventilation, absence of negative controls, missing hydrogen data, and a thermodynamics violation; the authors defend their work and plan a spring CCZ expedition to test the phenomenon, but many experts say the study should be retracted unless the evidence is revised.

Trump accelerates deep-sea mining push, drawing global backlash

The Trump administration unveiled a consolidated permitting process to search for and commercially extract minerals on the deep seabed, including areas beyond national jurisdiction, and shortened environmental reviews by allowing exploration and recovery licenses to be filed together. The move, framed as countering China’s influence, has sparked international and scientific condemnation for potentially bypassing UNCLOS/ISA rules and risking unknown impacts on oceans and coastal communities, even as some companies pledge not to source from the deep sea.

Deep-Sea Mission Set to Verify Dark Oxygen From Ocean Nodules

Scientists plan two 11-km-deep landers in the Clarion-Clipperton Zone to test whether metallic seabed nodules emit oxygen, a controversial claim dubbed 'dark oxygen.' The study, which could reshape ideas about life's origins, will measure seafloor respiration and rule out buoyant air artefacts while contending with mining industry skepticism; results are expected within days of deployment, with broader analyses following the ship’s June return.

Scientists Discover 'Dark Oxygen' 4,000 Meters Below Sea Level

Scientists have discovered that polymetallic nodules in the Clarion-Clipperton Zone produce 'dark oxygen' 4,000 meters below the sea surface, potentially rewriting our understanding of oceanic oxygen sources and the origins of life, while complicating deep-sea mining debates due to ecological concerns.

Underwater Eruption Chokes Marine Life with Ash Clouds

The 2022 eruption of the Hunga volcano caused significant ash deposition on the seafloor, damaging deep-sea ecosystems and affecting Tonga's coral reefs and local livelihoods. The study highlights the environmental impact of underwater volcanic activity and raises concerns about future deep-sea mining, which could cause similar or greater ecological harm.

Decades After 1979 Deep-Sea Mining, Pacific Ocean Remains Severely Damaged

A 1979 deep-sea mining experiment in the Pacific's Clarion-Clipperton Zone left lasting scars on the seafloor, with visible damage still evident 44 years later. While some small organisms are beginning to recolonize the area, the recovery of larger, stationary species is slow, raising concerns about the ecological impacts of future large-scale mining operations in this fragile ecosystem.

Unveiling the Mysterious Submarine 'Lost City'

The Lost City, an extraordinary underwater hydrothermal field located deep beneath the ocean near the Mid-Atlantic Ridge, features towering carbonate structures and unique microbial ecosystems that have existed for over 120,000 years. Its discovery offers insights into the origins of life and the potential for extraterrestrial life, but it faces threats from proposed deep-sea mining, prompting calls for its protection as a natural heritage site.

Norway Halts Deep-Sea Mining Plans Amid Controversy

Norway has paused its plans for commercial-scale deep-sea mining after political opposition from the Socialist Left Party, which threatened to withhold budget support unless the first licensing round was scrapped. The decision comes amid environmental concerns and opposition from 32 countries, including France and Germany. Prime Minister Jonas Gahr Stoer described the move as a "postponement," with further environmental research to be conducted. The suspension is seen as a victory by environmental groups like Greenpeace, while the country's energy ministry has yet to comment.

"Unveiling the Enigmatic Twilight Chorus of the Deep Sea"

Around twilight off Japan's Minamitorishima Island, fish create a chorus using their gas-filled swim bladders and fins, which can be heard 18,000 feet below the sea. Researchers recorded the soundscape of the abyss for a year and discovered daily fish choruses around sunset, suggesting deep-sea creatures may have circadian rhythms. The sounds could serve as a zeitgeber for deep-sea species, but the impact of potential deep-sea mining noise on these ecosystems requires further study.

"Norway's Controversial Move: Embracing Deep-Sea Mining to Challenge Rare Earths Dominance"

Norway's parliament has voted to approve deep-sea mining in a move to break China and Russia's rare earths dominance, despite warnings from scientists and environmental groups about the unknown environmental impacts. The decision puts Norway at odds with the U.K. and the European Commission, who have called for a temporary ban on deep-sea mining due to environmental concerns. Norway's government defends the decision, stating that it is necessary to explore sustainable ways to collect essential metals for the global transition away from fossil fuels, but critics argue that deep-sea mining will have vast negative impacts on marine life and the planet's health.

Norway's Controversial Decision: Greenlighting Deep-Sea Mining

Norway's parliament has voted in favor of opening up its seabed for commercial deep-sea mining, despite warnings from scientists and opposition from the EU and the UK due to environmental concerns. The decision, which is expected to speed up exploration of minerals in high demand for green technologies, has been criticized by environmental organizations and experts. The move will expose a large area to potential mining by companies, with the International Seabed Authority expected to finalize rules on deep-sea mining later this year.

"Norway's Parliament Greenlights Controversial Deep-Sea Mining in Arctic Ocean"

Norway's parliament has approved the exploration of a vast area of Arctic seabed for deep sea mining, despite concerns from environmental groups and scientists about the potential damage to marine life and ecosystems. The decision, which could make Norway the first country to engage in commercial deep sea mining, has sparked debate over the need for these resources in the green economy and the potential environmental costs. While proponents argue that deep sea mining could facilitate a faster transition to a low-carbon economy, critics emphasize the lack of knowledge about the deep ocean and its ecosystems, urging caution and a pause in deep sea mining activities.

"Norway Greenlights Deep-Sea Mining Despite Controversy"

Norway has approved commercial-scale deep-sea mining in its national waters, becoming the first country to do so, despite concerns from environmental scientists about the potential devastating impact on marine life. The move aims to accelerate the hunt for precious metals critical for green technologies, but has faced criticism from both external sources and Norwegian experts. The government plans to issue licences cautiously, requiring companies to submit proposals with environmental assessments, and estimates that actual extraction may not begin until the early 2030s. Critics argue that more investment should go into recycling and reusing existing minerals, while negotiations continue on whether licences could be issued for international seas.

Norway Set to Greenlight Controversial Deep-Sea Mining

Norway is set to approve a proposal to open its waters for deep-sea mining, making it one of the first countries to do so. The plan, which has received cross-party support, would allow companies to apply for licenses to mine for critical minerals near the Svalbard archipelago. While advocates argue that deep-sea mining is necessary for the global transition away from fossil fuels, critics and scientists warn of its potentially destructive environmental impacts and the lack of understanding of deep-sea habitats and biodiversity. The proposal has faced opposition from environmental groups, EU lawmakers, and the Norway Environment Agency, as well as conflicting with the U.K. and the European Commission's push for a temporary ban on deep-sea mining due to environmental concerns.
