1. The process begins when you exhale carbon dioxide (CO2) into the atmosphere. This CO2 can then be absorbed by the surface of the ocean. Once in the ocean, the CO2 can be used by phytoplankton, which are tiny plant-like organisms that live in the upper, sunlit layers of the ocean.

Phytoplankton use CO2, sunlight, and nutrients to photosynthesize, a process that converts CO2 and water into sugars and oxygen. These sugars provide the energy that phytoplankton need to grow and reproduce.

Some species of phytoplankton also use CO2 to make their shells, which are made of calcium carbonate. They do this through a process called calcification, where they combine calcium ions from the seawater with carbonate ions to form calcium carbonate.

When phytoplankton die, they sink towards the seafloor. If they are not eaten by other organisms on the way down, they can reach the seafloor and become part of the sediment. Over time, layers of this sediment can harden into rock, trapping the carbon within the seafloor.

2. An increase in atmospheric carbon dioxide is causing an increase in hydrogen ions (H+) in the world’s oceans. This is because when CO2 dissolves in seawater, it reacts with water to form carbonic acid, which then dissociates to form bicarbonate ions and hydrogen ions.

This increase in hydrogen ions is making the oceans more acidic, a process known as ocean acidification. This is problematic for shell-building organisms such as phytoplankton because the increased acidity can dissolve their calcium carbonate shells. Additionally, the excess hydrogen ions in the water can react with carbonate ions to form bicarbonate ions, reducing the availability of carbonate ions that phytoplankton need to build their shells.
