The ocean’s ability to sequester carbon away from the atmosphere exerts an important control on global climate. The biological pump drives carbon storage in the deep ocean and is thought to function via gravitational settling of organic particles from surface waters. However, the settling flux alone is often insufficient to balance mesopelagic carbon budgets or to meet the demands of subsurface biota. Here we review additional biological and physical mechanisms that inject suspended and sinking… 

Microbes contribute to setting the ocean carbon flux by altering the fate of sinking particulates

Sinking particulate organic carbon out of the surface ocean sequesters carbon on decadal to millennial timescales. Predicting the particulate carbon flux is therefore critical for understanding both

A Visual Tour of Carbon Export by Sinking Particles

The diversity of sinking particles that transport carbon into the ocean’s interior, their contribution to carbon export, and their attenuation with depth are resolved to better quantify the ocean's biological carbon pump.

Drawdown of Atmospheric pCO2 Via Variable Particle Flux Stoichiometry in the Ocean Twilight Zone

The strength of the biological soft tissue pump in the ocean critically depends on how much organic carbon is produced via photosynthesis and how efficiently the carbon is transferred to the ocean

Quantifying the Carbon Export and Sequestration Pathways of the Ocean's Biological Carbon Pump

The ocean's biological carbon pump transfers carbon from the surface ocean to the deep ocean by several distinct pathways, including gravitational settling of organic particles, mixing and advection

Efficient Particle Transfer to Depth in Oxygen Minimum Zones of the Pacific and Indian Oceans

The remineralization depth of sinking organic particles controls the efficiency of the biological carbon pump by setting the sequestration timescale of remineralized carbon in the ocean interior.

Biological Carbon Pump Sequestration Efficiency in the North Atlantic: A Leaky or a Long‐Term Sink?

The North Atlantic Ocean is a key region for carbon sequestration by the biological carbon pump (BCP). The quantity of organic carbon exported from the surface, the region and depth at which it is

Uncertain response of ocean biological carbon export in a changing world

The transfer of organic carbon from the upper to the deep ocean by particulate export flux is the starting point for the long-term storage of photosynthetically fixed carbon. This ‘biological carbon

What Is Refractory Organic Matter in the Ocean?

About 20% of the organic carbon produced in the sunlit surface ocean is transported into the ocean’s interior as dissolved, suspended and sinking particles to be mineralized and sequestered as

Biogeochemical‐Argo data suggest significant contributions of small particles to the vertical carbon flux in the subpolar North Atlantic

The biological carbon pump exerts a strong control on atmospheric CO2 levels. It includes a range of processes that generate organic carbon in the surface ocean and transport this organic matter from

Biogenic sinking particle fluxes and sediment trap collection efficiency at Ocean Station Papa

Comprehensive field observations characterizing the biological carbon pump (BCP) provide the foundation needed to constrain mechanistic models of downward particulate organic carbon (POC) flux in the



Revisiting Carbon Flux Through the Ocean's Twilight Zone

A large variability in transfer efficiency of sinking particulate organic carbon between 150 and 500 meters of 20 and 50% at two contrasting sites is measured, which is equivalent to a difference in carbon sequestration of more than 3 petagrams of carbon per year.

Attenuation of sinking particulate organic carbon flux through the mesopelagic ocean

There is a significant relationship between the remineralization depth of sinking organic carbon flux in the upper ocean and water temperature, with shallower reminalization in warmer waters, suggesting that predicted future increases in ocean temperature will result in reduced CO2 storage by the oceans.

Remineralization of particulate organic carbon in an ocean oxygen minimum zone

The sensitivity of zooplankton to ocean oxygen concentrations can have direct implications for atmospheric carbon sequestration and future expansion of OMZs is likely to increase biological ocean carbon storage and act as a negative feedback on climate change.

Seasonal copepod lipid pump promotes carbon sequestration in the deep North Atlantic

It is shown that one species, the copepod Calanus finmarchicus overwintering in the North Atlantic, sequesters an amount of carbon equivalent to the sinking flux of detrital material.

Mesoscale ocean fronts enhance carbon export due to gravitational sinking and subduction

It is shown that the flux of sinking particles (typically considered the dominant form of downward transport of organic carbon) is twice as high at a frontal system, relative to surrounding waters or to nonfrontal conditions.

Eddy-driven subduction exports particulate organic carbon from the spring bloom

It is shown that a dynamic eddying flow field subducts surface water with high concentrations of nonsinking POC, and can contribute as much as half of the total springtime export of POC from the highly productive subpolar oceans.

Deep ocean nutrients imply large latitudinal variation in particle transfer efficiency

Deep ocean particle fluxes are reconstructed by diagnosing the rate of nutrient accumulation along transport pathways in a data-constrained ocean circulation model, revealing a global pattern of transfer efficiency to 1,000 m that is high at high latitudes and low in subtropical gyres, with intermediate values in the tropics.

Microbial production of recalcitrant dissolved organic matter: long-term carbon storage in the global ocean

The microbial carbon pump is proposed as a conceptual framework to address the important, multifaceted biogeochemical problem of fixed carbon in the upper ocean.

Reconciliation of the carbon budget in the ocean’s twilight zone

It is found that prokaryotes are responsible for 70 to 92 per cent of the estimated remineralization in the twilight zone despite the fact that much of the organic carbon is exported in the form of large, fast-sinking particles accessible to larger zooplankton.
