Oxygene - The Ocean Direct

The primary source of ocean oxygen is microscopic organisms known as . These tiny, plant-like drifters live in the "photic zone"—the top 200 meters of the ocean where sunlight can reach.

: Single-celled algae that also contribute significantly to the oxygen cycle. Does the ocean produce oxygen? Oxygene - The Ocean

The ocean is far more than just a body of water; it is often referred to as the "lungs of the planet," responsible for producing roughly of the world's oxygen . While the vast majority of this comes from surface-level photosynthesis, recent groundbreaking discoveries have revealed that the deep ocean also produces its own "dark oxygen". 1.
