In a groundbreaking discovery, scientists have found evidence of oxygen production in the deep ocean, shocking the scientific community and challenging long-held beliefs about the origin of our planet's oxygen. The unexpected revelation has been attributed to polymetallic nodules found in the Pacific Ocean, approximately 13,000 feet (3,962 meters) below the surface.

Traditionally, it was believed that oxygen production relied solely on photosynthetic organisms such as plants and algae. However, this new research suggests that metallic minerals, specifically polymetallic nodules, may also play a significant role in the production of precious oxygen.

The revelation originated during a research expedition in the Clarion-Clipperton Zone, a large mountainous formation located far off the coast of South America. Andrew Sweetman, a researcher with the Scottish Association for Marine Science, and his team stumbled upon the evidence while collecting samples from the seabed.

Initially, the discovery left Sweetman and his team perplexed, as previous studies had only observed oxygen consumption in the deep sea. However, further investigation led them to the realization that the polymetallic nodules contained crucial elements such as cobalt, nickel, copper, lithium, and manganese - all of which are essential components of batteries.

Northwestern University chemist Franz Geiger, who was consulted for an explanation, theorized that combining rust with saltwater could generate electricity. Applying this concept to the polymetallic nodules, Geiger hypothesized that they could produce enough electricity to facilitate the production of oxygen through seawater electrolysis.

Upon examining a single sample of the nodules, researchers discovered that it produced 0.95 volts of power, which accounted for two-thirds of the amount required for seawater electrolysis. Geiger described the finding as a natural "geobattery" and suggested it as a potential explanation for the dark oxygen production in the ocean's depths.

The implications of this discovery are far-reaching. Large-scale mining companies are now aiming to extract these precious elements from the seafloor at depths of 10,000 to 20,000 feet (3,048 to 6,096 meters). However, Geiger warns of the need to rethink mining methods to avoid depleting the oxygen source for deep-sea life.

This unexpected breakthrough has prompted scientists to reconsider their understanding of where aerobic life may have originated. The presence of oxygen in the deep sea, where light is scarce, raises questions about the potential for life to exist in even more extreme environments.

As further research delves into the capabilities of electric rocks and their role in oxygen production, this discovery marks a significant advancement in our understanding of our planet's intricate mechanisms. It serves as a reminder that we still have much to discover about the depths of our oceans and the vital processes occurring within them.
