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

Science of the Total Environment, 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.

Metrics that matter for assessing the ocean biological carbon pump [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2020
The biological carbon pump (BCP) comprises wide-ranging processes that set carbon supply, consumption, and storage in the oceans’ interior. It is becoming increasingly evident that small changes in the efficiency of the BCP can significantly alter ocean carbon sequestration and, thus, atmospheric CO 2

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

Proceedings of the National Academy of Sciences of the United States of America, 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 ...

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

Frontiers 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]

iScience, 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,

Model estimates of metazoans' contributions to the biological carbon pump [PDF]

Biogeosciences, 2023
The daily vertical migrations of fish and other metazoans actively transport organic carbon from the ocean surface to depth, contributing to the biological carbon pump. We use an oxygen-constrained, game-theoretic food-web model to simulate diel vertical

The ocean's biological carbon pump under pressure. [PDF]

Sci Adv
Increasing hydrostatic pressure induces the release of dissolved organic matter from rapidly settling marine particles and contributes to the depth attenuation of carbon fluxes.

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

Nature, 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.

Autonomous Observations of the Ocean Biological Carbon Pump [PDF]

Oceanography, 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.

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

Biogeosciences, 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.
