Autonomous Observations of the Ocean Biological Carbon Pump [PDF]

open access: yesOceanography, 2009
Prediction of the substantial biologically mediated carbon flows in a rapidly changing and acidifying ocean requires model simulations informed by observations of key carbon cycle processes on the appropriate spatial and temporal scales.

Pathways of Organic Carbon Downward Transport by the Oceanic Biological Carbon Pump [PDF]

open access: yesFrontiers in Marine Science, 2019
The oceanic biological carbon pump (BCP) regulates the Earth carbon cycle by transporting part of the photosynthetically fixed CO2 into the deep ocean. Suppressing this mechanism would result in an important increase of atmospheric CO2 level.

The biological carbon pump, diel vertical migration, and carbon dioxide removal. [PDF]

open access: yesiScience, 2023
Carbon dioxide is increasing in the atmosphere promoting the faster environmental change of the Earth's recent history. Several marine carbon dioxide removal (mCDR) technologies were proposed to slow down CO2 in the atmosphere. Technologies now under experimentation are related to the increase in gravitational flux. Other mechanisms such as active flux,

Biological carbon pump estimate based on multidecadal hydrographic data. [PDF]

open access: yesNature, 2023
AbstractThe transfer of photosynthetically produced organic carbon from surface to mesopelagic waters draws carbon dioxide from the atmosphere1. However, current observation-based estimates disagree on the strength of this biological carbon pump (BCP)2.

The role of mixotrophic protists in the biological carbon pump [PDF]

open access: yesBiogeosciences, 2014
The traditional view of the planktonic food web describes consumption of inorganic nutrients by photoautotrophic phytoplankton, which in turn supports zooplankton and ultimately higher trophic levels.

The biological carbon pump in CMIP6 models: 21st century trends and uncertainties. [PDF]

open access: yesProc Natl Acad Sci U S A, 2022
The biological carbon pump (BCP) stores ∼1,700 Pg C from the atmosphere in the ocean interior, but the magnitude and direction of future changes in carbon sequestration by the BCP are uncertain. We quantify global trends in export production, sinking organic carbon fluxes, and sequestered carbon in the latest Coupled Model Intercomparison ...

Rapid photoacclimation during episodic deep mixing augments the biological carbon pump. [PDF]

open access: yesLimnol Oceanogr, 2021
AbstractEpisodic deep mixing events are one component of the biological carbon pump that physically transports organic carbon into the mesopelagic. Episodic deep mixing also disrupts summertime thermal stratification thereby changing the light field and nutrient concentrations available for phytoplankton growth.

The value of scientific research on the ocean's biological carbon pump. [PDF]

open access: yesSci Total Environ, 2020
The ocean's biological carbon pump (BCP) sequesters carbon from the surface to the deep ocean and seabed, constituting one of Earth's most valuable ecosystem services. Significant uncertainty exists surrounding the amounts and rates of organic carbon sequestered in the oceans, however.

Precessional pacing of tropical ocean carbon export during the Late Cretaceous [PDF]

open access: yesClimate of the Past, 2022
The marine biological carbon pump, which exports organic carbon out of the surface ocean, plays an essential role in sequestering carbon from the atmosphere, thus impacting climate and affecting marine ecosystems.

The influence of the ocean circulation state on ocean carbon storage and CO2 drawdown potential in an Earth system model [PDF]

open access: yesBiogeosciences, 2018
During the four most recent glacial cycles, atmospheric CO2 during glacial maxima has been lowered by about 90–100 ppm with respect to interglacials. There is widespread consensus that most of this carbon was partitioned in the ocean.
