Biological pump - Wikipedia
The biological pump is responsible for transforming dissolved inorganic carbon (DIC) into organic biomass and pumping it in particulate or dissolved form into the deep ocean.
9.3.2: Biological Pump - Geosciences LibreTexts
2023年12月27日 · The oceanic biological carbon pump (BCP) is a complex mechanism regulating the Earth carbon (C) cycle by sequestrating part of the photosynthetically fixed CO 2 into the deep ocean and the seafloor.
What is the Biological Carbon Pump? - Ocean Info
The three types of carbon pumps refer to the processes that move carbon from the surface ocean into the deep sea, effectively removing it from the atmosphere for extended periods. These are the biological pump, the carbonate pump, and the physical pump, also known as …
Hidden biological processes can affect how the ocean stores carbon
6 天之前 · The biological pump. Marine snow – a mixture of dead phytoplankton, bacteria, fecal pellets, and other organic particles – absorbs about a third of human-made carbon dioxide from the ...
Understanding the Role of the Biological Pump in the Global …
The oceanic biological pump—the complex suite of processes that results in the transfer of particulate and dissolved organic carbon from the surface to the deep ocean—constitutes the main mechanism for removing CO2 from the atmosphere and sequestering carbon at depth on submillennium time scales.
Biological Carbon Pump
Biological Carbon Pump. Half of the photosynthesis that occurs in the world happens in the oceans, fixing carbon dioxide and giving us oxygen in return. Despite this, surprisingly little is known about the cycle and the environmental dynamics that may influence the process.
Biological Pump :: Ocean Carbon & Biogeochemistry
Biological Pump. Marine organisms play a critical role in the global carbon cycle via the biological carbon pump. In the well-lit surface ocean, primary producers use sunlight for energy and dissolved inorganic nutrients to transform dissolved CO 2 into organic carbon.
The Marine Biological Pump - SpringerLink
The biological pump, orchestrated by minute phytoplankton, removes CO 2 from the atmosphere, depositing it in ocean sediments for centuries. This vital process mitigates global warming by capturing 25–50% of the CO 2 produced by humans.
The Oceans’ Biological Carbon Pumps: Framework for a Research ...
2021年11月28日 · A recent paradigm explains that the downward pumping of biogenic carbon in the ocean is performed by the combined action of six different biological carbon pumps (BCPs): the biological gravitational pump, the physically driven pumps (Mixed Layer Pump, Eddy Subduction Pump and Large-scale Subduction Pump), and the animal-driven pumps (diurnal ...
The ocean’s ‘biological pump’ captures more carbon than expected
2020年4月6日 · When phytoplankton die or are eaten by zooplankton, the carbon-rich fragments sinks deeper into the ocean, where it is, in turn, eaten by other creatures or buried in sediments. This process is key to the “biological carbon pump,” an important part of the global carbon cycle.
