Optical properties and bioavailability of dissolved organic matter along a flow-path continuum from soil pore waters to the Kolyma River mainstem, East Siberia [PDF]

, 2016
The Kolyma River in northeast Siberia is among the six largest Arctic rivers and drains a region underlain by vast deposits of Holocene-aged peat and Pleistocene-aged loess known as yedoma, most of which is currently stored in ice-rich permafrost ...

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 ...

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.

Removal of chromophoric dissolved organic matter under combined photochemical and microbial degradation as a response to different irradiation intensities.

Journal of Environmental Science, 2022
Throughout the freshwater continuum, Dissolved Organic Carbon (DOC) and the colored fraction, Chromophoric Dissolved Organic Material (CDOM), are continuously being added, removed, and transformed, resulting in changes in the chromophoricity and lability

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).

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.

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.

Picocyanobacteria and deep-ocean fluorescent dissolved organic matter share similar optical properties

Nature Communications, 2017
The sources of marine chromophoric dissolved organic matter and associated fluorescent DOM (FDOM) remain unclear. Here, the authors demonstrate that picocyanobacteria release FDOM similar to typical fluorescent signals found in the ocean, and are likely ...
