Chromophoric Dissolved Organic Matter (CDOM): chemical structure and PARAFAC analysis [PDF]

, 2018
The structure(s), distribution and dynamics of CDOM have been investigated over the last several decades largely through optical spectroscopy (including both absorption and fluorescence) due to the fairly inexpensive instrumentation and the easy-to-gather data (over thousands published papers from 1990-2016). Yet, the chemical structure(s) of the light

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 ...

The optical characteristics and sources of chromophoric dissolved organic matter (CDOM) in seasonal snow of northwestern China [PDF]

The Cryosphere, 2018
Abstract. Chromophoric dissolved organic matter (CDOM) plays an important role in the global carbon cycle and energy budget but is rarely studied in seasonal snow. A field campaign was conducted across northwestern China from January to February 2012, and surface snow samples were collected at 39 sites in Xinjiang and Qinghai provinces.

Formation of Chromophoric Dissolved Organic Matter by Bacterial Degradation of Phytoplankton-Derived Aggregates

Frontiers in Marine Science, 2018
Organic matter produced and released by phytoplankton during growth is processed by heterotrophic bacterial communities that transform dissolved organic matter into biomass and recycle inorganic nutrients, fueling microbial food web interactions ...

CDOM spectral slope (S275–295) as tracers of water masses, CDOM heterogeneity, and Δ14C‐DOC in an oligotrophic marginal sea

Limnology and Oceanography Letters, 2023
The absorption spectral slope, S275–295, is an optical metric frequently employed for characterizing chromophoric dissolved organic matter (CDOM). We collected CDOM absorption (aCDOM) and fluorescence spectra from the oligotrophic offshore South China ...

Remote Sensing Estimation of CDOM and DOC with the Environmental Implications for Lake Khanka

Remote Sensing, 2023
Chromophoric dissolved organic matter (CDOM) is a significant contributor to the biogeochemical cycle and energy dynamics within aquatic ecosystems. Hence, the implementation of a systematic and comprehensive monitoring and governance framework for the ...

UV Absorption Spectral Characteristics of Dissolved Organic Matter in Fen River of Taiyuan in China

E3S Web of Conferences, 2018
UV absorption is one of the important properties of chromophoric dissolved organic matter (CDOM). The UV absorption spectral characteristics of dissolved organic matter (DOM) were analyzed to infer the main components in Taiyuan urban section.

Environmental Calibration of Coral Luminescence as a Proxy for Terrigenous Dissolved Organic Carbon Concentration in Tropical Coastal Oceans

Geochemistry, Geophysics, Geosystems, 2022
The riverine flux of terrigenous dissolved organic matter (tDOM) to the ocean is a significant contributor to the global carbon cycle. In response to anthropogenic drivers the flux is expected to increase.

Properties and dynamics of chromophoric dissolved organic matter (CDOM) in Eastern Mediterranean waters [PDF]

, 2021
Ο σκοπός της εργασίας είναι η διερεύνηση των οπτικών ιδιοτήτων της Διαλυτής Οργανικής Ύλης, DOM, σε μια μεγάλη περιοχή της Ανατολικής Μεσογείου η οποία καλύπτει τη Θάλασσα του Μαρμαρά, το Βόρειο-Κεντρικό και Νότιο Αιγαίο, το Νότιο Ιόνιο, τη Βορειοδυτική Θάλασσα της Λεβαντίνης καθώς και το Σπερχειό Ποταμό.

Photoalteration of macrophyte-derived chromophoric dissolved organic matter induces growth of single bacterial populations in a coastal lagoon

Journal of Limnology, 2013
Photochemical degradation is an important process involved in the decay of macrophytes, but little is known on the response of heterotrophic bacteria to the chromophoric dissolved organic matter (CDOM) derived from different plant species.
