Oxygen enters oceans primarily through two processes: diffusion from the atmosphere and photosynthesis by marine plants. In the first process, oxygen from the air dissolves into the surface of the ocean, especially in areas with waves or turbulence. In the second process, phytoplankton and other aquatic plants produce oxygen as a byproduct of photosynthesis, contributing significantly to the overall oxygen levels in ocean waters. Together, these mechanisms help maintain the balance of oxygen necessary for marine life.
