Particulate organic matter as a functional soil component for persistent soil organic carbon [PDF]

Nature Communications, 2021
Abstract The largest terrestrial organic carbon pool, carbon in soils, is regulated by an intricate connection between plant carbon inputs, microbial activity, and the soil matrix. This is manifested by how microorganisms, the key players in transforming plant-derived carbon into soil organic carbon, are controlled by the physical ...

Assessment of hydrology, sediment and particulate organic carbon yield in a large agricultural catchment using the SWAT model [PDF]

, 2011
The Soil and Water Assessment Tool (SWAT, 2005) was used to simulate discharge and sediment transport at daily time steps within the intensively farmed Save catchment in south-west France (1110 km2).

Microbial-mediated contribution of kelp detritus to different forms of oceanic carbon sequestration

Ecological Indicators, 2022
Kelp is one of the most important primary producers in the coastal oceans. When it matures or begins to decay, a substantial amount of detritus sinks and is degraded by microorganisms.

Enhanced rates of particulate organic matter remineralization by microzooplankton are diminished by added ballast minerals [PDF]

, 2013
To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness in rolling tanks with and without added calcite minerals (coccoliths) and ...

How is particulate organic carbon transported through the river-fed submarine Congo Canyon to the deep sea? [PDF]

Biogeosciences
The transfer of carbon from land to the near-coastal ocean is increasingly being recognized in global carbon budgets. However, a more direct transfer of terrestrial organic carbon to the deep sea is comparatively overlooked.

Fluvial transport of suspended sediment and organic carbon during flood events in a large agricultural catchment in southwest France. [PDF]

, 2011
Water draining from a large agricultural catchment of 1 110 km2 in southwest France was sampled over an 18-month period to determine the temporal variability in suspended sediment (SS) and dissolved (DOC) and particulate organic carbon (POC) transport ...

Stable carbon and radiocarbon isotope compositions of particle size fractions to determine origins of sedimentary organic matter in an estuary [PDF]

, 2002
Stable and radioactive carbon isotopic compositions of particle size fractions of a surface sediment from the Ems-Dollard estuary vary considerably with particle size. The organic material in the fine fractions (

THE MEASUREMENT OF DISSOLVED ORGANIC AND PARTICULATE CARBON IN SEAWATER1 [PDF]

Limnology and Oceanography, 1964
A method is described for the rapid determination of dissolved organic carbon in seawater in concentrations between 0.1 and 20 mg/liter. The oxidation is carried out in sealed glass ampoules using K2S2O8 as an oxidizing agent after the sample has been freed of inorganic carbon. The resulting CO2 is passed through a nondispersive infrared analyzer using

Biodegradability of dissolved organic carbon in permafrost soils and aquatic systems: A meta-analysis [PDF]

, 2015
As Arctic regions warm and frozen soils thaw, the large organic carbon pool stored in permafrost becomes increasingly vulnerable to decomposition or transport.

Organic carbon and nitrogen export from a tropical dam-impacted floodplain system [PDF]

, 2013
Tropical floodplains play an important role in organic matter transport, storage, and transformation between headwaters and oceans. However, the fluxes and quality of organic carbon (OC) and organic nitrogen (ON) in tropical river-floodplain systems are ...
