Rice Export Carbon Emissions and Reduction Measures

DEStech Transactions on Environment, Energy and Earth Sciences, 2017
China is a large produce country in rice cultivation. Rice paddies carbon emission is one of the main sources of carbon emissions in agricultural activities. This study estimated the carbon emissions in the process of rice cultivation and export. It is suggested that choose the low carbonization cultivation patterns, such as the low carbonization rice ...

Controls on carbon export in the subtropical North Atlantic

Progress in Oceanography, 2020
Abstract We present a lower trophic level pelagic ecosystem model that allows the investigation of the role of hydrography, bacterial remineralization and detritus consumption on the strength of carbon export and its attenuation. We apply the model to investigate the controls on the carbon export at the Bermuda Atlantic Time-Series Study site (BATS ...

Human impact on long‐term organic carbon export to rivers [PDF]

Journal of Geophysical Research: Biogeosciences, 2017
AbstractAnthropogenic landscape alterations have increased global carbon transported by rivers to oceans since preindustrial times. Few suitable observational data sets exist to distinguish different drivers of carbon increase, given that alterations only reveal their impact on fluvial dissolved organic carbon (DOC) over long time periods.

Perfusion Bioreactor Culture Incorporating Mechanical Confinement Enhances Mesenchymal Stem Cell Extracellular Vesicle Production and Wound Healing Potential

Advanced Materials Technologies, EarlyView.
Scalable manufacturing challenges and limited potency remain two of the most intransigent issues limiting clinical translation of EV therapeutics. Mechanical cues can induce phenotypic changes and increased vesiculation in EV source cells without the use of extraneous reagents, chemicals, and/or cargo, thereby potentially drastically improving the ...

Atmospheric pCO2 Response to Stimulated Organic Carbon Export: Sensitivity Patterns and Timescales

Geophysical Research Letters
The ocean's organic carbon export is a key control on atmospheric pCO2 and stimulating this export could potentially mitigate climate change. We use a data‐constrained model to calculate the sensitivity of atmospheric pCO2 to local changes in export ...

Photochemical enrichment of dissolved organic matter from different soils of a tidal river basin: significance to estuarine carbon cycle

Frontiers in Marine Science
Eroded soils sustain a substantial part of organic matter in tidal rivers adjacent to estuaries, and photochemical transformations of soils in tidal rivers would influence estuarine elemental cycles. However, complex aquatic environments and diverse soil

Controls on the composition and lability of dissolved organic matter in Siberia's Kolyma River basin [PDF]

, 2012
High-latitude northern rivers export globally significant quantities of dissolved organic carbon (DOC) to the Arctic Ocean. Climate change, and its associated impacts on hydrology and potential mobilization of ancient organic matter from permafrost, is ...

Multifaceted contribution of coccolithophores to ocean carbon export

Ocean-Land-Atmosphere Research
Coccolithophores, a type of unicellular calcifying algae, are widely distributed across the global ocean. They contribute to the ocean carbon cycle by producing organic and inorganic carbon. Hence, they function as multifaceted contributors to oceanic carbon pumps, the biological carbon pump (BCP) and the carbonate counter pump (CCP).

Diagnosing Mechanisms of Ocean Carbon Export in a Satellite-Based Food Web Model

Frontiers in Marine Science, 2020
The net primary productivity (NPP) of marine phytoplankton is ∼50 Pg C year–1, and roughly 10–20% of this NPP is exported out of the surface ocean as sinking particulate organic carbon (POC). Numerous mechanisms are hypothesized to control POC export out
