At depths beyond 200 meters, the twilight zone of the ocean is a fascinating region where photosynthesis ceases and strange lifeforms thrive. Scientists explore its biodiversity and its vital role in carbon absorption and marine ecosystems.

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...

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

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.

"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 #SETILive, 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.
