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 ...

Dataset on optical characteristics and spectroscopic indices of dissolved organic matter of the Kara, Laptev, and East Siberian seas in August–September 2017

Data in Brief, 2019
A total of 137 water samples to study optical properties of chromophoric dissolved organic matter were collected in the Artic shelf seas during the 69th cruise on board the R/V Akademik Mstislav Keldysh in August–September 2017.

The characteristics of dissolved organic matter (DOM) and chromophoric dissolved organic matter (CDOM) in Antarctic sea ice [PDF]

Deep Sea Research Part II: Topical Studies in Oceanography, 2011
Abstract An investigation of coloured dissolved organic matter (CDOM) and its relationships to physical and biogeochemical parameters in Antarctic sea ice and oceanic water have indicated that ice melt may both alter the spectral characteristics of CDOM in Antarctic surface waters and serve as a likely source of fresh autochthonous CDOM and labile ...

Evolution of dissolved and particulate chromophoric materials during the VAHINE mesocosm experiment in the New Caledonian coral lagoon (south-west Pacific) [PDF]

Biogeosciences, 2016
In the framework of the VAHINE project, we investigated the spectral characteristics and the variability of dissolved and particulate chromophoric materials throughout a 23-day mesocosm experiment conducted in the south-west Pacific at the mouth of the ...

Dissolved Organic Carbon Source Attribution in the Changjiang Outflow Region of the East China Sea

Sensors, 2021
The variable optical properties of chromophoric dissolved organic matter (CDOM) under the complicated dynamic marine environment make it difficult to establish a robust inversion algorithm for quantifying the dissolved organic carbon (DOC).

Comparing Chromophoric Dissolved Organic Matter Methodologies

Journal of Student Research, 2019
Chromophoric dissolved organic matter (CDOM) is a combination of plant and animal decomposition byproducts and the optically active component of dissolved organic matter (DOM) in water. CDOM measurements have been a focus in the literature related to aqueous environments since the 1980s.

Flux and Seasonality of Dissolved Organic Matter From the Northern Dvina (Severnaya Dvina) River, Russia [PDF]

, 2018
Pan‐Arctic riverine dissolved organic carbon (DOC) fluxes represent a major transfer of carbon from land‐to‐ocean, and past scaling estimates have been predominantly derived from the six major Arctic rivers. However, smaller watersheds are constrained to

Technical Note: Comparison of storage strategies of sea surface microlayer samples [PDF]

, 2013
The sea surface microlayer (SML) is an important biogeochemical system whose physico-chemical analysis often necessitates some degree of sample storage.

Comparative Evaluation of Additives in Softwood Fractionation: Impacts on Lignin Recovery and Pulp Quality. [PDF]

ChemSusChem
Chemical lignin stabilization during acid hydrotropic fractionation is shown to distinctly influence delignification, lignin quality, and pulp performance. Phenol enhances lignin removal, while thiol‐based modifier yields light‐colored lignin, high recovery, and strong pulp.
