Is the ocean the source of carbon dioxide?

I have heard that the ocean is vast, and it is most important to the earth's ecology. But the ocean is the main source of carbon dioxide?

The ocean is vast, contains all things and contains vitality. Or think that the ocean is a reservoir of carbon dioxide, covering plankton in the water for photosynthesis, which can absorb carbon and release oxygen. However, some commentators say that the ocean is also a place where carbon dioxide is released.

Looking at reality, changes in seawater temperature have a great impact. When the water temperature rises, the solubility of carbon dioxide in the water decreases, and it then escapes into the atmosphere. And the decomposition of organic matter at the bottom of the ocean will also produce carbon dioxide, which will then rise to the sea surface and disperse into the air.

In addition, the state of ocean circulation also affects the transport and migration of carbon dioxide. Cold and warm currents meet, and water bodies mix, promoting the exchange of carbon dioxide between the ocean and the atmosphere. If the circulation is abnormal, the dynamics of carbon dioxide will also change.

Overall, the ocean can be a store of carbon dioxide and its source from time to time. Its role is determined by many factors such as water temperature, circulation and biological activities. The relationship between the ocean and carbon dioxide is intricate, and it needs to be deeply explored by the academic community to clarify it in detail and provide evidence for ecological conservation, climate research and other things.
