How long does it take for carbon dioxide to be absorbed by the ocean

It will take decades, if not centuries.

Once carbon dioxide is absorbed by the ocean, it often takes decades or even centuries to settle and settle on the seafloor. Currently, almost all the carbon dioxide produced by human activities is still present. the surface layer of the ocean.

There are two main ways the ocean absorbs carbon dioxide: First, carbon dioxide can be dissolved in water (the approximate ratio is that 1 volume of water dissolves 1 volume of carbon dioxide) to “store” carbon. dioxide. Second, marine organisms (mainly algae) absorb carbon dioxide through photosynthesis. The absorption effect of this marine organism is very important, because the carbon dioxide absorbed by algae photosynthesis constitutes the largest amount of carbon dioxide absorbed by plants in the world.
