Marine organic carbon

Marine organic carbon refers to the carbon that is contained within living organisms and organic materials in the ocean. It includes substances like phytoplankton (tiny plants), zooplankton (tiny animals), and dead organic matter such as fallen leaves and other debris. This organic carbon plays a vital role in the Earth's carbon cycle by absorbing carbon dioxide during photosynthesis and, when organisms die, transporting carbon into deep ocean layers. This process helps regulate the planet's climate and supports marine ecosystems by providing energy and nutrients throughout the food web.
