Carbon export by vertically migrating zooplankton:Optimal vertical migration and carbon export [PDF]
, 2016 Through diel vertical migration (DVM), zooplankton add an active transport to the otherwise passive sinking of detrital material that constitutes the biological pump. This active transport has proven difficult to quantify. We present a model that estimates both the temporal and depth characteristic of optimal DVM behavior based on a trade-off between ...

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.

Hydrologic Regime Determines Catchment‐Scale Dissolved Carbon Export Patterns
Water Resources ResearchHydrologic regimes are affecting terrestrial carbon transformation, chemical weathering and lateral transport. However, its impacts on dissolved carbon export patterns remains elusive.

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 ...

Greening Wine Exports? Changes in the Carbon Footprint of Spanish Wine Exports [PDF]
International Journal of Environmental Research and Public Health, 2021 Spain is one of the leading wine-producing and -exporting countries and has traditionally been dominant in trade and world production in the sector. In an increasingly changing context, in which worldwide wine exports are growing exponentially, it is essential to study their impact on climate change as the transport of goods generates a significant ...

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.

Drivers of Carbon Export Efficiency in the Global Ocean. [PDF]
Global Biogeochem 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).

Export of Carbon from Chloroplasts at Night [PDF]
Plant Physiology, 1998 AbstractHexose export from chloroplasts at night has been inferred in previous studies of mutant and transgenic plants. We have tested whether hexose export is the normal route of carbon export from chloroplasts at night. We used nuclear magnetic resonance to distinguish glucose (Glc) made from hexose export and Glc made from triose export.

A mechanistic model of an upper bound on oceanic carbon export as a function of mixed layer depth and temperature [PDF]
Biogeosciences, 2017 Export production reflects the amount of organic matter transferred from the ocean surface to depth through biological processes. This export is in large part controlled by nutrient and light availability, which are conditioned by mixed layer depth ...

China's “Exported Carbon” Peak: Patterns, Drivers, and Implications [PDF]
Geophysical Research Letters, 2018 AbstractOver the past decade, China has entered a “new normal” phase in economic development, with its role in global trade flows changing significantly. This study estimates the driving forces of Chinese export‐embodied carbon emissions in the new normal phase, based on environmentally extended multiregional input‐output modeling and structural ...
