Detailed explanation-1: -Out of total global carbon, 70 percent carbon is found dissolved in the ocean.
Detailed explanation-2: -The Earth’s largest carbon stock is found within the continental crusts and upper mantle of the Earth, a large portion of which is sedimentary rock formed over millions of years (2).
Detailed explanation-3: -Most of Earth’s carbon-about 65, 500 billion metric tons-is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.
Detailed explanation-4: -Carbon from the atmosphere enters the ocean depths in areas of deep water formation in the North Atlantic and offshore of the Antarctic Peninsula. Where deep currents rise towards the surface, they can release “fossil” carbon dioxide stored centuries ago.
Detailed explanation-5: -The ocean generates 50 percent of the oxygen we need, absorbs 25 percent of all carbon dioxide emissions and captures 90 percent of the excess heat generated by these emissions. It is not just ‘the lungs of the planet’ but also its largest ‘carbon sink’ – a vital buffer against the impacts of climate change.
