Drivers of Carbon Export Efficiency in the Global Ocean [PDF]
Global Biogeochemical Cycles, 2019 AbstractThe export of organic carbon from the surface ocean forms the basis of the biological carbon pump, an important planetary carbon flux. Typically, only a small fraction of primary productivity (PP) is exported (quantified as the export efficiency: export/PP).

A Visual Tour of Carbon Export by Sinking Particles. [PDF]
Global Biogeochem Cycles, 2021 Abstract To better quantify the ocean's biological carbon pump, we resolved the diversity of sinking particles that transport carbon into the ocean's interior, their contribution to carbon export, and their attenuation with depth. Sinking particles collected in sediment trap gel layers from four distinct ocean ecosystems were imaged ...

Mixotrophic plankton foraging behaviour linked to carbon export. [PDF]
Nat Commun, 2022 Marine mixotrophic protists that use both heterotrophic and phototrophic metabolisms may impact the carbon cycle in unexpected ways. A recently characterized mixotroph can craft three-dimensional mucilage feeding structures that trap nutrient-rich plankton prey and contribute to the sinking of carbon from the surface ocean.

Long term carbon export from mountain forests driven by hydroclimate and extreme event driven landsliding [PDF]
Communications Earth & EnvironmentThe export of organic carbon from terrestrial ecosystems by erosion may play a central role in balancing the geological carbon cycle and Earth’s climate over millennial timescales.

Adaptive carbon export response to warming in the Sargasso Sea. [PDF]
Nat Commun, 2022 AbstractOcean ecosystem models predict that warming and increased surface ocean stratification will trigger a series of ecosystem events, reducing the biological export of particulate carbon to the ocean interior. We present a nearly three-decade time series from the open ocean that documents a biological response to ocean warming and nutrient ...

Influence of carbon tariffs on China’s export trade [PDF]
Environmental Science and Pollution Research, 2021 The database of the Global Trade Analysis Project (GTAP) and its energy-environmental model, known as GTAP-E, are used in this study to simulate the effect of the simultaneous and separate carbon tariff impositions of EU, the USA, and Japan on the export and export structure in China.

Ironing out carbon export to the deep ocean. [PDF]
Proc Natl Acad Sci U S A, 2015 In PNAS, Lopes et al. (1) present a novel approach to quantifying the efficiency of the biological carbon pump as Earth’s climate warmed from the ice bound glacial episode (26,000–18,000 y before present) to the equable climate of the present interglacial (10,000 y BP until present). The biological carbon pump begins with atmospheric CO2 transformation

Extreme 2016 El Niño heatwave weakened carbon export and respiration in the Equatorial Pacific [PDF]
Communications Earth & EnvironmentThe 2016 El Niño was the strongest warm-phase of the El Niño-Southern Oscillation recorded to date over the 21st century, leading to the development of severe ocean surface temperature anomalies - marine heatwaves - across the equatorial Pacific. Here we

Tectonically-triggered sediment and carbon export to the Hadal zone. [PDF]
Nat Commun, 2018 AbstractSediments in deep ocean trenches may contain crucial information on past earthquake history and constitute important sites of carbon burial. Here we present 14C data on bulk organic carbon (OC) and its thermal decomposition fractions produced by ramped pyrolysis/oxidation for a core retrieved from the >7.5 km-deep Japan Trench.

Efficient biological carbon export to the mesopelagic ocean induced by submesoscale fronts [PDF]
Nature CommunicationsOceanic submesoscale processes are ubiquitous in the North Pacific Subtropical Gyre (NPSG), where the biological carbon pump is generally ineffective.
