Deep Ocean Particle Flux in the Northern South China Sea: Variability on Intra-Seasonal to Seasonal Timescales

Frontiers in Earth Science, 2020
Based on a time-series sediment trap observation at a depth of 1,003-m in the northern South China Sea from 2014 to 2015, we used sinking particle flux combined with remote sensing-derived environmental data to infer the mechanisms of the biological ...

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 ...

Identifying Saharan dust driven export of biogenic material in the ultraoligotrophic eastern Mediterranean Sea

Frontiers in Marine Science
To assess the effects of dust deposition on the strength of the biological pump in the Mediterranean Sea by acting as fertilizer and/or ballasting agent, we analyzed fluxes of mineral dust, particulate organic carbon (POC) and inorganic carbon (PIC), and

The Roles of Suspension-Feeding and Flux-Feeding Zooplankton as Gatekeepers of Particle Flux Into the Mesopelagic Ocean in the Northeast Pacific

Frontiers in Marine Science, 2019
Zooplankton are important consumers of sinking particles in the ocean’s twilight zone. However, the impact of different taxa depends on their feeding mode.

The Influence of Air‐Sea CO2 Disequilibrium on Carbon Sequestration by the Ocean's Biological Pump

Global Biogeochemical Cycles
The ocean's biological carbon pump (BCP) affects the Earth's climate by sequestering CO2 away from the atmosphere for decades to millennia. One primary control on the amount of carbon sequestered by the biological pump is air‐sea CO2 disequilibrium ...

Modeling the Impact of Zooplankton Diel Vertical Migration on the Carbon Export Flux of the Biological Pump

Global Biogeochemical Cycles, 2019
One pathway of the biological pump that remains largely unquantified in many export models is the active transport of carbon from the surface ocean to the mesopelagic by zooplankton diel vertical migration (DVM).

Drivers and fluxes of dissolved organic carbon along the northern Antarctic Peninsula during late summer [PDF]

Anais da Academia Brasileira de Ciências
Dissolved organic carbon (DOC) is a key component of the biogeochemical carbon cycle in the Southern Ocean. However, there are still significant gaps in understanding the role of DOC in polar environments, due to the limitations of spatiotemporal ...

Temporal and regional variabilities in the attenuation of sinking particulate organic carbon in the Kuroshio region

Frontiers in Marine Science, 2022
The biological pump that transports carbon from the surface ocean to the ocean interior is an important determinant of ocean carbon absorption from the atmosphere, and of biological activity beneath the euphotic zone.

Estimating Carbon Flux From Optically Recording Total Particle Volume at Depths Below the Primary Pycnocline

Frontiers in Marine Science, 2019
Optical instruments can rapidly determine numbers and characteristics of water column particles with high sensitivity. Here we show the usefulness of optically assessed total particle volume below the main pycnocline to estimate carbon export in two ...
