At least half of the oxygen produced on Earth comes from the ocean, mostly from tiny photosynthesizing plankton. But marine life also uses roughly the same amount of oxygen to breathe, for cellular respiration, and in the decomposition process.

We now know that more than half the planet’s oxygen comes from the ocean. Not the entire ocean—just the top 200 meters (656 feet) or so. That’s about as far as sunlight can travel through water to power photosynthesis.
13 Σεπ 2017 · Plankton that are plants, known as phytoplankton, grow and get their own energy through photosynthesis and are responsible for producing an estimated 80% of the world’s oxygen.
24 Ιουν 2020 · Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton – drifting plants, algae, and some bacteria –...
Oxygen is produced naturally via a relatively simple process: photosynthesis. In photosynthesis, green plants take in carbon dioxide, water, and sunlight. With these “ingredients” the plant then produces sugars (which it uses as food) and oxygen (which it expels into the air around it).
8 Ιουν 2023 · Oxygen is mostly taken up into the Ocean in the cold waters of the high latitudes, in which oxygen is most soluble. When this water sinks into deeper waters, it oxygenates deeper parts of the...
The consequences of oxygen loss in the Ocean are extensive and include decreased biodiversity, shifts in species distributions, displacement or reduction in fisheries resources, changes in biogeochemical cycling and mass mortalities.
