Question

Scientists are very curious about the carbon cycle and how much carbon dioxide the ocean can hold. Why?

Answer 1

Oceans Absorb Less Carbon Dioxide as Marine Systems Change. The oceans are by far the largest carbon sink in the world. Some 93 percent of carbon dioxide is stored in algae, vegetation, and coral under the sea. But oceans are not able to absorb all of the carbon dioxide released from the burning of fossil fuels.
