Predicting dissolved lignin phenol concentrations in the coastal ocean from chromophoric dissolved organic matter (CDOM) absorption coefficients

Frontiers in Marine Science, 2016
Dissolved lignin is a well-established biomarker of terrigenous dissolved organic matter (DOM) in the ocean, and a chromophoric component of DOM. Although evidence suggests there is a strong linkage between lignin concentrations and chromophoric DOM ...

Influence of environmental factors on spectral characteristics of chromophoric dissolved organic matter (CDOM) in Inner Mongolia Plateau, China [PDF]

Hydrology and Earth System Sciences, 2016
Spectral characteristics of chromophoric dissolved organic matter (CDOM) were examined in conjunction with environmental factors in the waters of rivers and terminal lakes within the Hulun Buir plateau, northeast China.

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 ...

Chromophoric dissolved organic matter (CDOM) in first-year sea ice in the western Canadian Arctic [PDF]

Marine Chemistry, 2014
We monitored the spatiotemporal progression of chromophoric dissolved organic matter (CDOM) in first-year sea ice in the western Canadian Arctic between mid-March and early July 2008. CDOM abundance in bottom ice, as quantified by absorption coefficient at 325 nm, a(CDOM)(325), showed a positive, linear relationship with the concentration of ...

Production of Chromophoric Dissolved Organic Matter (CDOM) in Laboratory Cultures of Arctic Sea Ice Algae [PDF]

Water, 2019
Chromophoric dissolved organic matter (CDOM) is highly enriched in bottom sea ice in the Arctic during ice algal blooms, giving rise to multifaceted ecological implications in both the sea ice and the underlying seawater. We conducted laboratory culture incubations to assess the potential role of ice algae in the accumulation of CDOM in Arctic sea ice.

Chromophoric dissolved organic matter (CDOM) variability over the continental shelf of the northern Bay of Bengal

Oceanologia, 2017
The present paper dealt with the annual dynamics of the absorption coefficient of chromophoric dissolved organic matter at 440 nm {aCDOM(440)} during February 2015 to January 2016 in the continental shelf of northern Bay of Bengal (nBoB) for the first time.

Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach. [PDF]

Environ Microbiol Rep
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Temperature Thresholds Govern Microbial-Mediated Dissolved Organic Carbon Dynamics in Coastal Ecosystems. [PDF]

Adv Sci (Weinh)
Coastal dissolved organic carbon (DOC) represents one of the largest reduced carbon pools on Earth, and they are influenced by temperature. Across 7.6–35.9 °C ranges, the microbial‐mediated DOC dynamics is characterized by three temperature thresholds.

Optical remote sensing of coloured dissolved organic matter (cdom) for better estimation of dissolved organic carbon (doc) in south-east Queensland water reservoirs [PDF]

, 2021
Australian inland water-bodies play a great role in the carbon cycle at the regional level and contribute effectively through the carbon exchange between their surface and the atmosphere.

Characteristics, sources and driving factors of riverine CDOM in a severe erosion basin on the Loess Plateau, China

Ecological Indicators, 2023
Chromophoric dissolved organic matter (CDOM) plays a crucial role in aquatic ecosystems and biogeochemical processes. The characteristics, sources and influencing factors of riverine CDOM were determined with 56 samples collected in the Wuding River (WDR)
