Scientists have discovered a strange phenomenon in which oxygen is being produced deep in the ocean on the abyssal seafloor, where sunlight cannot reach. This oxygen is not created by traditional photosynthesizing plants, but rather by metallic nodules that split water molecules into hydrogen and oxygen. The lead scientist of the study, Andrew Sweetman, initially believed his equipment was faulty when it showed oxygen production in the dark sea floor, but eventually realized the significance of this discovery.
This discovery challenges the traditional understanding of oxygen production, as it has always been believed that only photosynthetic organisms can create oxygen. Around half of the Earth’s oxygen comes from the ocean, produced by oceanic plankton, drifting plants, algae, and some bacteria through photosynthesis. However, these organisms would not be able to produce oxygen at such depths.
Mining companies are now interested in collecting these oxygen-producing modules, which contain ingredients like lithium, cobalt, and copper needed to make batteries. However, Sweetman’s study raises concerns about the risks involved in collecting these deep-sea minerals.
Overall, the discovery of oxygen production in the deep ocean raises questions about our current understanding of oxygen production and the potential environmental impact of mining these deep-sea minerals.
