Detailed explanation-1: -The largest (major) reservoir of carbon on earth is the deep oceans. The amount of carbon present in the ocean is about 37, 000 GtC, whereas in the atmosphere, it is about 750 GtC and in the biosphere, it is 610 GtC.
Detailed explanation-2: -The deep trenches in the ocean and the water in the ocean have rich dissolved carbon, the organic matters also serve as a source of carbon, the nutrient leaching and precipitation which occurs in the ocean plays a major role in making the ocean the large reservoir of carbon.
Detailed explanation-3: -The ocean is therefore the greatest of the carbon reservoirs, and essentially determines the atmospheric CO2 content. The carbon, however, requires centuries to penetrate into the deep ocean, because the mixing of the oceans is a rather slow (Chapter 1).
