NOAA and NASA commonly cite an estimate of about half of global gross photosynthetic O₂ production coming from the ocean. This counts initial oxygen release through photosynthesis and does not mean net accumulation: respiration by phytoplankton and other organisms, plus decomposition, consume substantial O₂. Organic carbon buried outside the fast decomposition cycle is what is associated with long-term increases in atmospheric oxygen. [1–3]
