If Earth loses its sources of oxygen, that won't be a very green transition. smh

#DeepSeaMining opponents suffer major setback

by Amélie BOTTOLLIER-DEPOIS
August 3, 2024

"Opponents of deep sea mining suffered a serious setback Friday when they failed to take a first step toward an international moratorium on the controversial practice.

"Until now, those in favor of such mining—which would deliver minerals key to the green transition but with a potentially high environmental cost—have managed to prevent the #InternationalSeabedAuthority (#ISA) from even taking up any debate on the subject.

"This time, the debate took place, but a draft calling for a 'dialogue' toward 'the development of a general policy... for the protection and preservation of the marine environment' did not advance after a week of talks in Kingston, Jamaica.

"Numerous delegations, from #China to #SaudiArabia to the #Africa group of member states, said the draft lacked clarity and that the ISA's full assembly of 168 members was not the forum to make any decision on the protection of #marine habitats.

"Instead, those countries said the Council, made up of 36 states, should decide.

"Faced with consistent opposition, #Chile withdrew the draft measure as the assembly's annual session—which makes decisions by consensus—drew to a close.

"'We are somewhat disappointed,' said Chilean representative Salvador Vega Telias. Though he believed he had support from a majority of states, he opted to shelve the discussions until July 2025—a proposal that was not approved either.

"Deep sea mining in international waters involves scraping the ocean floor for #minerals like #nickel, #cobalt and #copper, crucial for #RenewableEnergy energy technology.

"Under the UN Convention on the Law of the Sea (#UNCLOS), the ISA is responsible for both protecting the seabed in areas beyond national jurisdictions and for overseeing any exploration or exploitation of resources in those zones.

"Deep sea mining has not yet taken place beyond the experimental and exploratory stage.

"The ISA's Council, which for now only grants exploration contracts, has been drawing up commercial exploitation rules for more than a decade. They are aiming to adopt a mining code in 2025.

"Non-governmental organizations and scientists warn that deep sea mining could damage #habitats and harm species that are little understood, but are potentially important to the #FoodChain.

"In addition, they point to the risk of disrupting the ocean's capacity to absorb carbon emitted by human activities, and the noise that could disturb species such as #whales."

#Oxygen discovery defies knowledge of the deep ocean

Victoria Gill, Science correspondent, BBC
July 22, 2024

"Scientists have discovered '#DarkOxygen' being produced in the #DeepOcean, apparently by lumps of metal on the #seafloor.

"About half the oxygen we breathe comes from the #ocean. But, before this discovery, it was understood that it was made by marine plants photosynthesising - something that requires sunlight.

"Here, at depths of 5km, where no sunlight can penetrate, the oxygen appears to be produced by naturally occurring metallic '#nodules' which split seawater - H2O - into hydrogen and oxygen.

"Several #mining companies have plans to collect these nodules, which marine scientists fear could disrupt the newly discovered process - and damage any marine life that depends on the oxygen they make.

"'I first saw this in 2013 - an enormous amount of oxygen being produced at the seafloor in complete darkness,' explains lead researcher Prof Andrew Sweetman from the Scottish Association for Marine Science. 'I just ignored it, because I’d been taught - you only get oxygen through #photosynthesis.

"'Eventually, I realised that for years I’d been ignoring this potentially huge discovery,' he told BBC News.

"He and his colleagues carried out their research in an area of the deep sea between #Hawaii and #Mexico - part of a vast swathe of seafloor that is covered with these metal nodules. The nodules form when dissolved metals in seawater collect on fragments of shell - or other debris. It's a process that takes millions of years.

"And because these nodules contain metals like #lithium, #cobalt and #copper - all of which are needed to make batteries - many mining companies are developing technology to collect them and bring them to the surface.

"But Prof Sweetman says the dark oxygen they make could also support life on the seafloor [and life on Earth!]. And his discovery, published in the journal Nature Geoscience, raises new concerns about the risks of proposed deep-sea mining ventures.

"The scientists worked out that the metal nodules are able to make oxygen precisely because they act like batteries."

OMG! That's the same stuff some countries want to start mining! TY,

Mysterious Unknown #DeepSeaCreatures Discovered on Abyssal Expedition

By University of Gothenburg June 9, 2024

"Transparent #SeaCucumbers, pink sea pigs, and bowl-shaped sponges are some of the fascinating animals discovered during a deep-sea expedition to the #AbyssalPlains in the #PacificOcean.

"A 45-day research expedition to the Clarion Clipperton Zone between Mexico and Hawaii in the eastern Pacific Ocean ended in March. One of the scientists on board the British research vessel James Cook was Thomas Dahlgren, a marine ecologist from the University of Gothenburg and the NORCE research institute.

[...]

"Threatened by #Mining

"The aim of the expedition was to map the biodiversity of the area, where #DeepSeaMining of rare metals used in solar panels, electric car batteries, and other green technologies is planned. Several countries and companies are waiting for authorization to extract these metals bound to mineral #nodules lying on the ocean floor. The scientists want to find out more about how mining could affect the #ecosystem, register existing species, and find out how the ecosystem is organized.

“We need to know more about this environment to be able to protect the species living here. Today, 30% of these marine areas in consideration are protected, and we need to know whether this is enough to ensure that these species aren’t at risk of extinction,” says Dahlgren."
