marine carbon sinks

Marine carbon sinks are natural processes in the ocean that absorb and store carbon dioxide (CO₂) from the atmosphere, helping to regulate climate. Phytoplankton, tiny ocean plants, take in CO₂ during photosynthesis. When they die or are eaten, their remains sink to the deep ocean, carrying carbon with them. Additionally, certain marine sediments and sea floor rocks can trap carbon for long periods. These processes collectively remove significant amounts of CO₂ from the air, acting as a vital buffer against climate change by reducing the greenhouse effect.
