Ocean Carbon Sequestration

Ocean carbon sequestration refers to the process by which the ocean absorbs carbon dioxide (CO2) from the atmosphere and stores it. This occurs naturally through various mechanisms, such as photosynthesis by marine plants like phytoplankton, which use CO2 to grow. The ocean also captures CO2 through chemical reactions, turning it into bicarbonate and carbonate. These processes help mitigate climate change by reducing the amount of CO2 in the atmosphere. However, increased CO2 levels can also lead to ocean acidification, which can harm marine ecosystems. Thus, while the ocean plays a vital role in carbon storage, it faces significant environmental challenges.
