The sequestration efficiency of the biological pump [PDF]
Geophysical Research Letters, 2012 The conversion of dissolved nutrients and carbon to organic matter by phytoplankton in the surface ocean, and its downward transport by sinking particles, produces a “biological pump” that reduces the concentration of atmospheric CO2. Global rates of organic matter export are a poor indicator of biological carbon storage however, because organic matter

Microbial control of the dark end of the biological pump. [PDF]
Nat Geosci, 2013 A fraction of the carbon captured by phytoplankton in the sunlit surface ocean sinks to depth as dead organic matter and faecal material. The microbial breakdown of this material in the subsurface ocean generates carbon dioxide. Collectively, this microbially mediated flux of carbon from the atmosphere to the ocean interior is termed the biological ...

Variations in the biological pump throughout the Miocene: evidence from organic carbon burial in Pacific Ocean sediments [PDF]
Climate of the PastThe biological pump, defined as the marine biological production and sedimentation of particulate organic carbon (POC), is a fundamental process for fixing atmospheric carbon dioxide in the oceans, transferring carbon away from the atmosphere to the deep

The influence of the biological pump on ocean chemistry: implications for long-term trends in marine redox chemistry, the global carbon cycle, and marine animal ecosystems. [PDF]
Geobiology, 2016 The net export of organic matter from the surface ocean and its respiration at depth create vertical gradients in nutrient and oxygen availability that play a primary role in structuring marine ecosystems.

Southern Ocean Biological Pump Role in Driving Holocene Atmospheric CO2: Reappraisal
Geophysical Research LettersChanges in Southern Ocean biological pump efficiency are frequently invoked as a source of glacial/interglacial CO2 variability. It was recently suggested that Southern Ocean biological pump weakening also contributed to Holocene CO2 increase.

The ocean's biological carbon pump under pressure. [PDF]
Sci AdvIncreasing hydrostatic pressure induces the release of dissolved organic matter from rapidly settling marine particles and contributes to the depth attenuation of carbon fluxes.

Frontiers in Marine ScienceThe demand for marine living resources is increasing at an unprecedented scale because of the need for continuous food provision to the world’s population. The potential of already exploited fish stocks to meet this demand is limited.

Global upper ocean dissolved oxygen budget for constraining the biological carbon pump
Communications Earth & EnvironmentOne mechanism by which the ocean uptakes carbon dioxide is through the biological carbon fixation and its subsequent transport to the deep ocean, a process known as the biological carbon pump.

Review of algorithms estimating export production from satellite derived properties
Frontiers in Marine Science, 2023 Whereas the vertical transport of biomass from productive surface waters to the deep ocean (the biological pump) is a critical component of the global carbon cycle, its magnitude and variability is poorly understood.

Frontiers in Marine Science, 2022 Coastal acidification has been widely investigated in terms of its rationale and ecological effects in the last decade. However, the driving mechanism for acidification in open seawater, especially in mesopelagic water, is still poorly understood.
