"Dark Oxygen" production at the seafloor webinar by Prof Sweetman 2025May06 (3:00-4:30PM EDT, UTC-4).

He will share details of the discovery & evidence for it (hopefully discussing co-production of hydrogen!)

#Kerala fishermen up in arms against #DeepSeaMining proposal off #Kollam coast

March 22, 2025

"The fishermen in Kerala have already launched several protests against the proposed plan to open up the sea to private mining companies as part of the Union Government’s ‘Blue Economy’ initiative.

"All the fishermen’s associations stand united in their protests against this proposal, alleging that it would bring an end to the fisheries sector in the country, not only in the #ArabianSea but also in the #BayOfBengal.

“ 'The mining, according to the scientific report we have, can disturb the seabed and completely destroy fish spawning habitats. It can also release poisonous gases trapped on the #DeepSeaFloor, causing severe #environmental issues,' Kerala Minister for Fisheries, Saji Cherian, told PTI.

"He said that deep-sea mining requires huge investments and heavy machinery, meaning only #multinational #corporations will be involved, making these areas completely inaccessible to poor fishermen.

"The Kerala government, which is strongly opposing this project, passed a resolution in the Assembly urging the Centre to withdraw it.

"The Minister said the proposed site, off the Kollam shore in Kerala in the Arabian Sea, is very rich in marine resources and serves as a lifeline for fishermen from Kerala and other states.

“ 'We have a highly diverse and extensive fish population in this area. The mining will completely wipe out this habitat, severely affecting the livelihood of fishermen in our region,' Saji Cherian said."

#NPR: The U.S. takes a step toward allowing #mining on the ocean floor, a fragile #ecosystem

by Julia Simon, April 25, 2025

"President #Trump signed an executive order Thursday aimed at making it easier for companies to mine the deep seafloor, saying it would create 'a robust domestic supply for critical minerals.'

"There is currently no commercial-scale deep-sea mining anywhere in the world. But companies have long eyed the ocean floor as a potential source of metals like nickel, cobalt, manganese and copper, which are used in batteries for electric vehicles and other technologies.

"The world has no rulebook for deep-sea mining. One company is pushing forward anyway

"These metals can be found in potato-sized nodules lying on the ocean floor. Many of the nodules are in the middle of the Pacific ocean, beyond the legal territory of individual countries.

"Thursday's order might circumvent ongoing international negotiations to regulate deep-sea mining.

"Those regions have traditionally been overseen by an international organization, the #InternationalSeabedAuthority (#ISA). The ISA has hosted talks for years to try to hammer out a rulebook to govern a potential seabed mining industry. The U.S. did not ratify the treaty that governs the seabed, and is not a voting member of the ISA, though in the past under previous administrations it has respected the ISA process.

"In his executive order, Trump instructed federal agencies to expedite the process for reviewing and issuing permits for mining on the seafloor in both U.S. and international territory. It will use a U.S. law from 1980, the "#DeepSeabed Hard Mineral Resources Act."

"Scientists and environmental groups condemned the order, arguing that opening the deep seabed for mining could disrupt important marine ecosystems, and damage the fishing industry.

" 'This is being planned on some of the least resilient #ecosystems on the planet,' says Douglas McCauley, professor of ocean science at the University of California Santa Barbara. 'It would have #catastrophic biological consequences.'

"Underwater mining can create plumes of sediment that could suffocate marine life, and degrade the #FoodWebs that fish depend on, McCauley says.

"There are also important questions about whether we actually need to be mining the seabed to get enough of these minerals for technologies like batteries, says Micah Ziegler, assistant professor of energy and chemical systems at Georgia Institute of Technology.

"While a couple of years ago researchers were concerned about the limitations of land-based mining for metals like cobalt and nickel, a variety of alternative #battery chemistries have been developed that might reduce the need for those elements, Ziegler says."

'Dark oxygen': a deep-sea discovery that has split scientists

'Dark oxygen': a deep-sea discovery that has split scientists
Could lumpy metallic rocks in the deepest, darkest reaches of the ocean be making oxygen in the absence of sunlight?

Some scientists think so, but others have challenged the claim that so-called "dark oxygen" is being produced in the lightless abyss of the seabed.

The discovery—detailed last July in the journal Nature Geoscience—called into question long-held assumptions about the origins of life on Earth, and sparked intense scientific debate.

We may have discovered how dark oxygen is being made in the deep sea

A newly discovered mechanism could explain the shock finding last year that oxygen is produced by metallic nodules on the seafloor – and it might be happening on other planets, too

'Dark oxygen' mission takes aim at other worlds

Gas from the seafloor has scientists wondering if oxygen could be found in the oceans of other planets.
