A recent study published in the journal Nature Geoscience<\/em> has revealed a surprising phenomenon: the production of oxygen in complete darkness at the bottom of the ocean<\/strong> (abyssal zone)<\/strong>.\nThis discovery, made in the Clarion-Clipperton zone of the Pacific, challenges traditional conceptions of marine biogeochemical cycles. <\/p>\n\n

The research was conducted in the ocean abyss<\/strong>, where benthic chambers were placed to analyze chemical interactions on the seafloor.\nThese devices, designed to study extreme environments, detected increases in oxygen in conditions where sunlight<\/a><\/strong> does not penetrate<\/strong>. <\/p>\n\n

During the experiments, the scientists observed a significant increase of oxygen<\/a><\/strong>exceeding background concentrations by up to three times, suggesting active oxygen production<\/strong>.\nThe researchers propose that this phenomenon, called dark oxygen production (DOP)<\/strong>, could be the result of the electrolysis of seawater. electrolysis of seawater<\/a><\/strong>facilitated by electric potentials in the polymetallic nodules. <\/p>\n\n

This finding opens up new lines of research in marine biogeochemistry and also has profound implications for understanding how abyssal organisms can sustain themselves in environments lacking direct sunlight.<\/p>\n\n

The publication states that this study transforms our understanding of deep ecosystems and the processes that support life in extreme conditions.<\/p>\n\n

Likewise, the research team plans to continue exploring the conditions under which PDO occurs and its impact on the planet’s deepest and least understood ecosystems. planet<\/a><\/strong>.<\/p>\n\n
