: Warmer water holds less oxygen and creates "stratification," which prevents oxygen-rich surface water from mixing into the deep sea.
: Most of the ocean's oxygen comes from tiny marine plants, algae, and some bacteria that photosynthesize like land plants. oxygene_the_ocean
: Scientists recently discovered that metallic nodules on the deep seafloor can produce oxygen through a process called electrolysis, even in total darkness. Environmental Threats (Deoxygenation) : Warmer water holds less oxygen and creates
: While the ocean produces roughly 50% of Earth’s oxygen, marine life also consumes about the same amount through respiration. oxygene_the_ocean
