: Runoff from fertilizers and sewage causes massive algal blooms. When these algae die and decompose, the process consumes oxygen, creating "dead zones". Cultural Connection: Jean-Michel Jarre's Oxygène

Ocean oxygen levels are currently declining due to two primary human-driven factors: oxygene_the_ocean

: Warmer water holds less oxygen and creates "stratification," which prevents oxygen-rich surface water from mixing into the deep sea. : Runoff from fertilizers and sewage causes massive

: Most of the ocean's oxygen comes from tiny marine plants, algae, and some bacteria that photosynthesize like land plants. : Most of the ocean's oxygen comes from

: 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)

: While the ocean produces roughly 50% of Earth’s oxygen, marine life also consumes about the same amount through respiration.
