Ocean deoxygenation linked to ancient mesopelagic fish decline - Communications Earth & Environment Historical phases of ocean oxygen minimum are associated with near extinctions of mesopelagic fish, suggesting risks of future deoxygenation to marine fisheries due to warming, according to an analysi...

Ocean oxygen decline threatens deep-sea fish population, ocean health and carbon sequestration according to Mediterranean fossil evidence from the last 10,000 years including the last anoxic event.

Geopolymerization threatens the persistence of organic carbon associated with iron in anoxic environments - Nature Communications Geopolymers formed in the mineral-catalyzed reaction of organic molecules act as electron shuttles to accelerate microbial dissimilatory iron reduction, which severely threatens the stability of the i...
