Aged riverine particulate organic carbon in four UK catchments [PDF]

open access: yesScience of The Total Environment, 2015
The riverine transport of particulate organic matter (POM) is a significant flux in the carbon cycle, and affects macronutrients and contaminants. We used radiocarbon to characterise POM at 9 riverine sites of four UK catchments (Avon, Conwy, Dee, Ribble) over a one-year period.

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

open access: yesEcological 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.

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

open access: yes, 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).

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

open access: yesNature 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 ...

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

open access: yesBiogeosciences
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.

A summer time series of particulate carbon in the air and snow at Summit, Greenland [PDF]

open access: yes, 2007
Carbonaceous particulate matter is ubiquitous in the lower atmosphere, produced by natural and anthropogenic sources and transported to distant regions, including the pristine and climate-sensitive Greenland Ice Sheet.

MOdern River archivEs of Particulate Organic Carbon: MOREPOC

open access: yesEarth System Science Data, 2022
Abstract. The supply of particulate organic carbon (POC) associated with terrigenous solids transported to the ocean by rivers plays a significant role in the global carbon cycle. To advance our understanding of the source, transport, and fate of fluvial POC from regional to global scales, databases of riverine POC are needed, including elemental and ...

Atmospheric CO2 consumption by continental erosion : present-day controls and implications for the last glacial maximum [PDF]

open access: yes, 1998
The export of carbon from land to sea by rivers represents a major link in the global carbon cycle. For all principal carbon forms, the main factors that control the present-day fluxes at the global scale have been determined in order to establish global

Effects of land use on Soil Organic Carbon fractions in soils of Njala Landscape in Sierra Leone [PDF]

open access: yes, 2016
Soil organic carbon fractions reflect the difference in soil organic carbon from one land use to another, and it can be regarded as an indication of the degree of soil organic carbon deterioration or improvement.

Influence of Algal Production and Decomposition on the Carbon Isotope Signature of Labile Particulate Organic Matter on a Productive Continental Shelf Under the Stress of Coastal Hypoxia

open access: yesFrontiers in Marine Science, 2020
To better understand the sources and recycling of labile organic matter in coastal water, we studied the carbon isotope signature of particulate organic carbon (POC) and particulate amino acids, a major group of labile organic compounds, on the shelf of ...
