"#Agricultural runoff provides perfect nutrients for #methanogen growth.
#Fertilizer and animal waste washing into ocean systems creates nutrient-rich zones where these methanogens thrive like never before. #Nitrogen and #phosphorus pollution from farmland creates ideal conditions for explosive #microbial growth in #coastal waters and #DeepOcean areas. These agricultural inputs essentially act as fertilizer for #methane-producing microbes, creating a connection between #IndustrialFarming and atmospheric #GreenhouseGas levels that scientists never fully appreciated.
"Coastal regions near major agricultural areas show the highest concentrations of these supercharged methanogens, with some areas recording methane production levels ten times higher than baseline measurements. The problem compounds itself because areas with intensive farming also tend to have the strongest ocean currents, meaning these fertilized methanogen populations get distributed globally. Every season’s #AgriculturalRunoff creates new opportunities for these microbes to establish thriving colonies in previously stable ocean environments."

It's not enough that #Fukushima #RadioactiveWaterDumping will continue for years (centuries?), now #Japan wants to mine the #DeepSea and kill even more #OceanLife? WTF!
Japan hauls rare earth-rich mud from deep sea in bold test mission
Story by BeckhamLangford
Feburary 3, 2026"Japan’s own planners acknowledge the uncertainties. Jan briefings on the test mining plan stressed that, However, key aspects remain unknown, including the quality of the minerals and the economics of lifting and processing such vast volumes of mud. Mining the mud had previously been seen as too expensive compared with land-based deposits, and even with new technology, the cost of pumping, dewatering and refining the material at scale is still an open question. Analysts also point out that any move toward commercial production will face intense scrutiny from environmental regulators and coastal communities, who want clearer evidence on how sediment plumes, noise and habitat disruption will affect #DeepOcean #ecosystems around the site."

#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."
