Quantification of black carbon in urban soils [PDF]

, 2011
Black carbon (BC), which comprises partially combusted organic material such as char and soot, is a hazardous pollutant and contributor to global warming, but is also highly stable, and once deposited in soil contributes to long-term stocks of ...

Organic carbon transport and C/N ratio variations in a large tropical river: Godavari as a case study, India [PDF]

, 2005
This study gives an insight into the source of organic carbon and nitrogen in the Godavari river and its tributaries, the yield of organic carbon from the catchment, seasonal variability in their concentration and the ultimate flux of organic and ...

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).

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 ...

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 (

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 ...

Agro-residue biochar and N fertilizer addition mitigates CO2-C emission and stabilized soil organic carbon pools in a rain-fed agricultural cropland

International Soil and Water Conservation Research, 2021
Scarce carbon dioxide (CO2) emission data, soil organic carbon (Corg) and labile Corg pool index for croplands in sub-Saharan Africa (SSA) limits our ability to define regional CO2 flux and mitigation prospects provided by biochar amendment.

New organic matter degradation proxies: Valid in lake systems? [PDF]

, 2004
We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...
