Turnover time of fluorescent dissolved organic matter in the dark global ocean [PDF]

, 2015
Research articleMarine dissolved organic matter (DOM) is one of the largest reservoirs of reduced carbon on Earth. In the dark ocean (4200 m), most of this carbon is refractory DOM.

Characterisation of the semi-volatile component of Dissolved Organic Matter by Thermal Desorption – Proton Transfer Reaction – Mass Spectrometry [PDF]

, 2017
Proton Transfer Reaction – Mass Spectrometry (PTR-MS) is a sensitive, soft ionisation method suitable for qualitative and quantitative analysis of volatile and semi-volatile organic vapours. PTR-MS is used for various environmental applications including

The biogeochemistry of carbon across a gradient of streams and rivers within the Congo Basin [PDF]

, 2014
Dissolved organic carbon (DOC) and inorganic carbon (DIC and pCO2), lignin biomarkers and the optical properties of dissolved organic matter (DOM) were measured in a gradient of streams and rivers within the Congo Basin (Republic of Congo), with the aim ...

Peatland ditch blocking has no effect on dissolved organic matter (DOM) quality [PDF]

Hydrological Processes, 2018
AbstractThe globally widespread drainage of peatlands has often been shown to lead to increased concentrations and fluxes of dissolved organic carbon (DOC) in streams and rivers. Elevated DOC concentrations have implications for carbon cycling, ecosystem functioning, and potable water treatment.

Biological early diagenesis and insolation-paced paleoproductivity signified in deep core sediment organic matter

Scientific Reports, 2017
The dynamics of a large stock of organic matter contained in deep sediments of marginal seas plays pivotal role in global carbon cycle, yet it is poorly constrained.

Biodegradation of Dissolved Organic Matter (DOM) Released from Phytoplankton in Lake Biwa

Analytical Sciences, 2012
The biodegradation study of algal dissolved organic matter (DOM) released from Microcystis aeruginosa, Staurastrum dorsidentiferum and Cryptomonas ovata was carried out. The algal DOM released from Microcystis aeruginosa and Staurastrum dorsidentiferum is relatively stable, while a part of the algal DOM released from Cryptomonas ovata may be easily ...

Humic, terrestrially derived dissolved organic matter is associated with higher methylmercury concentrations in prairie wetland ponds

FACETS
Dissolved organic matter (DOM) comprises most of the organic matter in the water column of surface waters, playing important roles in biogeochemical cycles, including that of mercury. We characterized DOM in surface water of wetlands ponds located in the

Composition of dissolved organic matter within a lacustrine environment [PDF]

, 2011
Freshwater dissolved organic matter (DOM) is a complex mixture of chemical components that are central to many environmental processes, including carbon and nitrogen cycling.

Composition Wheels: Visualizing dissolved organic matter using common composition metrics across a variety of Canadian ecozones.

PLoS ONE, 2021
Dissolved organic matter (DOM) is a ubiquitous component of aquatic systems, impacting aquatic health and drinking water quality. These impacts depend on the mixture of organic molecules that comprise DOM.
