WebApr 6, 2024 · These tiny marine plants transfer vast amounts of organic carbon from the surface waters to the deep ocean – a process called the ocean biological carbon pump. Through the Biological Pump and Carbon Exchange Processes project, a project funded by ESA’s Science for Society Programme, scientists are using ocean colour satellite data … The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments. In other words, it is a biologically mediated process which results in … See more The element carbon plays a central role in climate and life on Earth. It is capable of moving among and between the geosphere, cryosphere, atmosphere, biosphere and hydrosphere. This flow of carbon is referred … See more Dissolved and particulate carbon Phytoplankton supports all life in the ocean as it converts inorganic compounds into organic … See more In the diagram on the right, phytoplankton convert CO2, which has dissolved from the atmosphere into the surface oceans (90 Gt yr ), into particulate organic carbon (POC) during primary production (~ 50 Gt C yr ). Phytoplankton are then consumed by copepods See more Changes in land use, the combustion of fossil fuels, and the production of cement have led to an increase in CO2 concentration in the atmosphere. At present, about one third (approximately 2 Pg C y = 2 × 10 grams of carbon per year) of anthropogenic … See more The first step in the biological pump is the synthesis of both organic and inorganic carbon compounds by phytoplankton in the uppermost, sunlit layers of the ocean.
