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.

The biological pump is the set of processes by which inorganic carbon (e.g., carbon dioxide) is fixed into organic matter via photosynthesis and then sequestered away from the atmosphere generally by transport into the deep ocean. This may be accomplished by the passive sinking of particulate organic matter, through the vertical migration of ...

The biological carbon pump refers to a series of biological processes that sequester carbon to the ocean floor, away from the Earth's atmosphere. The biological carbon pump has a greater impact today on carbon cycling than scientists ever thought.

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.

2020年9月10日 · What is the biological carbon pump? When sunlight hits the ocean’s surface waters, it stimulates tiny marine plants called phytoplankton to photosynthesize. This process removes carbon dioxide dissolved in the water as phytoplankton incorporate the …

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.

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.

This module is an introduction to the marine biological pump and uses representative organisms to demonstrate the interconnectivity between the biosphere and the global carbon cycle. Created by Katherine Heal while she was a graduate student in Oceanography at UW, this module complements other labs created by the UW PCC team as part of a year ...

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.

2017年10月16日 · The biological pump is the collection of marine biogeochemical processes that convert dissolved inorganic matter in the surface ocean into biomass and transport this to the ocean interior, where the biomass is returned to its original dissolved inorganic forms.
