According to the National Oceanic and Atmospheric Administration, around half of Earth's oxygen comes from the ocean. The production can typically be linked to oceanic plankton, drifting plants, algae and certain bacteria, with all four are capable of photosynthesis.
Scientists are searching for the explanation behind a rather strange phenomenon: at the bottom of the Pacific Ocean there are large amounts of oxygen being produced by an unknown source. The finding is odd, to say the least, considering that photosynthesis is impossible in such deep, dark depths.
“We have another source of oxygen on the planet, other than photosynthesis,” said Andrew Sweetman, a study co-author, and a sea- floor ecologist at the Scottish Association for Marine Science in Oban, UK.
