Lots of it. Fish pull it out through their gills. Also in lakes and rivers, too.
Of course!! How else do you think the animals (like dolphins) breath??
they produce oxygen in the oceans
they produce oxygen in the oceans
Oceans are bodies of water that make up the oxygen in our environment

nearly 2/3!lol i just copied the other guy!
Oceans generate about 50-80% of the oxygen we breathe, primarily through photosynthesis by phytoplankton and algae. This oxygen production plays a crucial role in regulating the Earth's atmosphere and supporting marine life.
"An increase in atmospheric oxygen"An increase in atmospheric oxygen
The bulk of atmospheric oxygen originates from photosynthesis by plants and phytoplankton in the oceans.
Photosynthesis and respiration
No. Humans contain a greater abundance of oxygen than the earth's crust. So do the oceans.
Around 80 percent of oxygen on Earth is produced by phytoplankton in the oceans. These microscopic organisms undergo photosynthesis, absorbing carbon dioxide and releasing oxygen into the atmosphere. Forests and other terrestrial plants also contribute significantly to oxygen production.
The three main sources of oxygen are photosynthesis by plants and algae, oxygen released during the breakdown of water molecules, and oxygen produced by phytoplankton in the oceans.
