Relicanthus sp. is a newfound species collected at 4,100 meters (13,450 feet) in the Clarion-Clipperton Zone. It lives on sponge stalks attached to polymetallic nodules that are of interest to the A source of 'dark oxygen' has been discovered on the sea floor. Credit: Cavan/Getty. Something is pumping out large amounts of oxygen at the bottom of the Pacific Ocean, at depths where a Scientists have discovered "dark oxygen" being produced in the deep ocean, apparently by lumps of metal on the seafloor. About half the oxygen we breathe comes from the ocean. So-called polymetallic nodules are common on the ocean's abyssal

plains, which are flat regions of the seafloor between 10,000 and 20,000 feet (3,000 to 6,000 m) below the ocean surface. The black polymetallic sea nodules, the nickel, manganese and cobalt rich mineral deposits, these balls form naturally deep under the sea. [File: Pallava Bagla/Corbis via Getty Images] Chugging quietly away in the dark depths of Earth's ocean floors, a spontaneous chemical reaction is unobtrusively creating molecular oxygen (O 2), all without the involvement of life. This unexpected discovery upends the long-standing consensus that it takes photosynthesizing organisms to produce The flat, pitch-black

seabed of the Pacific Ocean's Clarion-Clipperton Zone (CCZ) is littered with what looks like hunks of charcoal. These unuming mineral deposits, called polymetallic A deep sea shark and several eels are attracted to bait placed at the summit of the Cook seamount, as seen from the Pisces V submersible during a dive to the previously unexplored seamount off the A team of scientists led by Professor Andrew Sweetman at the U.K.'s Scottish ociation for Marine Science found that oxygen is being produced in complete darkness approximately 4,000 meters Sensor readings seemed to show that oxygen was being made on the seabed 4,000

metres (about 13,100 feet) below the surface, where no light can penetrate. Now research is challenging this long-held Oxygen discovery defies knowledge of the deep ocean (BBC): Scientists have unveiled a mysterious phenomenon: 'Dark Oxygen' production deep within the ocean's Twelve thousand feet under the ocean surface is a world of eternal midnight. No sunlight can penetrate to this depth to promote photosynthesis, so no plants are producing oxygen there. Yet, the In the total darkness of the depths of the Pacific Ocean, scientists have discovered oxygen being produced not by living organisms but by strange potato-shaped

metallic lumps that give off almost Traditionally, we have always believed that photosynthesis by plants and algae el our planet's oxygen supply, even in the deep ocean, providing the essential gas for life on Earth. However, an international team of scientists has made a startling discovery, finding "dark oxygen" in the deep "Dark oxygen" is being produced deep in the ocean, and scientists are baffled by the strange phenomenon, according to a new study. In science cl, kids learn that plants need sunlight to do Scientists have discovered that metallic nodules on the seafloor produce their own oxygen in the dark depths of

the Pacific Ocean. These polymetallic nodules, generating electricity like AA batteries, challenge the belief that only photosynthetic organisms create oxygen, potentially altering our understanding of how life began on Earth. In the total darkness of the depths of the Pacific Ocean A new form of oxygen production has been detected on the ocean floor, raising concerns about the impact of deep-sea mining to this vital ecosystem. Researchers have discovered large amounts of Metals on the deep-ocean floor produce "dark oxygen" 13,000 feet below the surface, a new study has suggested. The finding challenges long-held umptions

that only photosynthetic organisms - those which use sunlight, water and carbon dioxide to create el and oxygen - such as plants and algae generate Earth's oxygen. Scientists have discovered that metal nodules on the ocean floor are producing oxygen in total darkness without any aid from living organisms, which could upend our understanding of the origin of A discovery in the dark depths of the Pacific Ocean is challenging the scientific consensus of how oxygen is produced and has even called into question how l Scientists have discovered 'dark oxygen' being produced in the deep ocean, apparently by lumps of metal on the

seafloor. About half the oxygen we breathe comes from the ocean. But, before this Marine researchers were surveying a mountain range in the depths of the Pacific Ocean when they noticed something strange.. Instruments deplo by the team kept registering a rise in oxygen Scientists have discovered 'dark oxygen' 13,100 feet deep in the Pacific Ocean, challenging long-held beliefs about oxygen production in the deep sea.
