Role of zooplankton in determining the efficiency of the biological carbon pump [PDF]
Biogeosciences, 2017 The efficiency of the ocean's biological carbon pump (BCPeff – here the product of particle export and transfer efficiencies) plays a key role in the air–sea partitioning of CO2. Despite its importance in the global carbon cycle, the biological processes

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

Decadal trends in air‐sea CO2 exchange in the Ross Sea (Antarctica) [PDF]
Geophysical Research Letters, 2016 Highly productive Antarctic shelf systems, like the Ross Sea, play important roles in regional carbon budgets, but the drivers of local variations are poorly quantified.

Sea Ice Loss leads to regime shifts in the arctic biological pump [PDF]
Nature CommunicationsThe Arctic Ocean has undergone accelerated warming and a marked decline in sea ice over recent decades. Yet, the response of the biological pump—a critical mechanism for atmospheric carbon sequestration—remains poorly understood.

The oceanic physical injection pump of organic carbon [PDF]
Nature CommunicationsThe contribution of the ocean biological carbon pump to the export of organic carbon at depth has predominantly been assessed by considering sinking particulate matter and vertically migrating organisms.

Evaluating the biological pump efficiency of the Last Glacial Maximum ocean using δ13C [PDF]
Climate of the Past, 2021 Although both physical and biological marine changes are required to explain the 100 ppm lower atmospheric pCO2 of the Last Glacial Maximum (LGM, ∼21 ka) as compared to preindustrial (PI) times, their exact contributions are debated.

COMMENTARY | Understanding the Role of the Biological Pump in the Global Carbon Cycle: An Imperative for Ocean Science [PDF]
Oceanography, 2014 Anthropogenically driven climate change will rapidly become Earth's dominant transformative influence in the coming decades. The oceanic biological pump—the complex suite of processes that results in the transfer of particulate and dissolved organic ...

Carbon sequestration by multiple biological pump pathways in a coastal upwelling biome
Nature Communications, 2023 Multiple processes transport carbon into the deep ocean as part of the biological carbon pump, leading to long-term carbon sequestration. However, our ability to predict future changes in these processes is hampered by the absence of studies that have ...
