There is more oxygen in the air.
Oxygen enters seawater primarily through diffusion from the atmosphere at the ocean's surface. This process allows oxygen to dissolve in the surface waters, where it can be used by marine organisms for respiration. Ocean mixing and circulation also help distribute oxygen throughout different depths of the seawater column.
Yes, cold air typically contains more oxygen than warm air. This is because cold air is denser and can hold more molecules, including oxygen.
Yes, cold air typically has more oxygen compared to warm air because cold air is denser and can hold more oxygen molecules.
Oxygen enters seawater through diffusion from the atmosphere at the water's surface and through photosynthesis carried out by marine plants and phytoplankton.
Inhaled air has more oxygen compared to exhaled air. When we inhale, we take in fresh oxygen from the environment to use for cellular respiration. As we exhale, we release carbon dioxide and the remaining oxygen that was not used by the body.
Two sources of oxygen in seawater at the surface include atmospheric exchange, where oxygen from the air dissolves into the water, and photosynthesis by marine plants and phytoplankton, which produce oxygen as a byproduct.
In modern submarines, the electrolyser separates oxygen from hydrogen in seawater to produce breathable oxygen. There is also a scrubber that removes excess CO2 from the air.

Seawater is more dense than air. That is why the air rests on top of the seawater and not the other way around.
Strangely enough, oceans are oxygen neutral in transferring to / from the air. Oxygen is liberated from water by plankton, and consumed by the various animal cells. There is some minor oxygen exchange with rainfall, wave breaking near shores / shoals, and some carried into the ocean by rivers, etc. Oceans *do*absorb large quantities of carbon dioxide directly from the air... which really hurts the coral reefs.
whisky (ie ethanol)gasoline (and other hydrocarbons) oxygen (for oxygen tanks, distilled from air) water from seawater essential oils for perfume.
Fish and marine life are able to live because oxygen is soluble in water, including salt water/seawater.
Seawater and fresh water contains oxygen that fish absorb using their gill. So the substance is oxygen.
