We almost know nothing about the deep sea, which is unfortunate not only from the science view, but malevolent profiteers with unsatiable greed are set up to destroy it for profits. It's high time to take care...

Sixty-six percent of the entire planet is #DeepOcean (≥200 m), and our data show that we have visually observed less than 0.001%, a total area approximately a tenth of the size of Belgium: science.org/doi/10.1126/sciadv -> Guess how much of the ocean floor humans have explored: nature.com/articles/d41586-025

The #DeepOcean is home to fragile #ecosystems, unique #species, and critical #CarbonSinks that help regulate global #climate. #Mining the ocean floor will destroy these ecosystems and release toxic #pollutants, leading to irreparable damage to ocean #biodiversity.

We know this is a longer post, but understanding the full context is crucial. The fact that #companies can now exploit this #loophole in #InternationalWaters

Explanatory graphic of a ship - production support vessel - connected to three machines with long pipes. First one in 800 - 2500 metres deep for cobalt-rich ferromanganese crusts. The second in 1000- 4000 metres deep for polymetallic sulphides and the third one in 4000- 6000 metres deep for polymetallic nodules.

Deep-sea mining is coming. And the U.S. is about to open the floodgates. 

The Metals Company (TMC), a controversial deep-sea mining corporation, is applying for permits under US mining law, a loophole that could allow them to exploit thr seabed in international waters.

On Sept 24, 1952, the oceanographic survey  vessel Kaiyo-Maru No 5 was destroyed by a  submarine eruption  
MISSING  
JAPANESE  SHIP  
SURVEY  
Searchers Have Narrow Escape  ToKto, Friday.-A Pacific volcano, believed  to have killed a party of Japanese survey  men. erupted again to-day in a deadly  sulphur shower, and nearly swamped five  boatloads of searchers for the missing party.  The boats, searching 200 miles south of  here for the survey ship Kaiyo Maru,  scattered at top speed when the Myojin Reef,  which sprang out of the water only a week  ago, exploded afresh Sulphur slush swept  across the ocean for a mile off the red-hot  isle, which the 31 men in the Kaiyo Maru-  nine scientists and a crew of 22-were  investigating.  
Maritime officials feared that the 200-ton  Kaiyo Maru, missing since Wednesday, was  sunk by a giant wave of molten rock hurled  from the volcano after an explosion early on  Wednesday.  
Three American Air Force 'planes took  off from coastal bases in Japan to-day to  aid in the search. which was hindered by bad  weather, At nightfall the five patrol boats  returned to the scene, searching the  sulphurous water for oil or wreckage, but  found no trace of the missing men.-Reuter

Point Nemo's remoteness and harsh conditions make it the perfect resting place for space debris. It also would be a perfect place for stargazing due to the minimal light pollution there.

#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."

Fascinating, gives hope for Life elsewhere in the Universe.....but also, leave those nodules where they are.

Buried #kelp: seaweed carried to the #DeepSea stores more carbon than we thought theconversation.com/buried-kel

#Carbon export from #seaweed forests to deep ocean sinks: Karen Filbee-Dexter et al. nature.com/articles/s41561-024

"coastal vegetation such as seaweed forests are more important to natural carbon storage than we thought. Around 56 million tonnes of carbon in the form of seaweed is carried into the #DeepOcean each year"

In this week's , Beth Johnson chatted with Dr. Bonnie Teece about her initial analysis of microbial traps left on the floor of the Atlantic Ocean near Axial Seamount and what they could mean for our search for life beyond Earth, especially involving ocean worlds like Europa and Enceladus.

Radioactive waste, baby bottles and Spam: the deep ocean has become a dumping ground.

The ocean’s depths are not some remote alien realm, but are in fact intimately entangled with every other part of the planet. We should treat them that way

Not-so-fun fact about being #Neurodivergent... Having sensory issues with lighting, and having low-wattage #incandescent light bulbs be banned, while #BigOilAndGas make obscene profits and do nothing to plug up #MethaneLeaks! (In fact, they want to dig up more holes -- in the #DeepOcean!).
