Chromophoric dissolved organic matter export from U.S. rivers [PDF]

Geophysical Research Letters, 2013
Chromophoric dissolved organic matter (CDOM) fluxes and yields from 15 major U.S. rivers draining an assortment of terrestrial biomes are presented. A robust relationship between CDOM and dissolved organic carbon (DOC) loads is established (e.g., a350 versus DOC; r2 = 0.96, p < 0.001).

Modeling the spectral shape of absorption by chromophoric dissolved organic matter

Marine Chemistry, 2004
A single exponential model of the form a g (λ)αe -s c λ was evaluated in the context of its application and interpretation in describing absorption by chromophoric dissolved organic matter (CDOM), a g , as a function of wavelength, λ. The spectral slope, s e , is often used as a proxy for CDOM composition, including the ratio of fulvic to humic acids ...

Rhizodeposition and litter decomposition of Phragmites australis play important roles in composition and properties of soil dissolved organic matter

Ecological Indicators, 2022
The dynamics of composition and properties of dissolved organic matter in soil depend on plant carbon inputs and microbial degradation. However, uncertainties remain regarding the relative contributions of different plant carbon inputs sources, i.e ...

Distribution, spectral characteristics, and seasonal variation of dissolved organic matter in the northern Beibu Gulf, South China Sea

Frontiers in Marine Science, 2022
Dissolved organic matter (DOM) in the land–ocean interface plays a critical role in the global carbon cycle, yet its dynamic is not well understood. Dissolved organic carbon (DOC) in the northern Beibu Gulf was measured seasonally from April 2020 to ...

The importance of the dissolved organic matter pool for the carbon sequestration potential of artificial upwelling

Frontiers in Marine Science, 2022
In the face of climate change there is a need to reduce atmospheric CO2 concentrations. Artificial upwelling of nutrient-rich deep waters has been proposed as a method to enhance the biological carbon pump in oligotrophic oceanic regions in order to ...

Characteristics of Dissolved Organic Matter and Trihalomethane Forming Potential Occurrence in Watersheds with Different Upstream Land Use

Environment and Natural Resources Journal, 2023
Dissolved organic matter (DOM) is the most important natural organic matter (NOM) fraction which reacts with chlorine to form harmful trihalomethanes (THMs) in water bodies. The characteristics of DOM could be affected by land use in the catchment, hence

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 ...

Factors regulating the compositions and distributions of dissolved organic matter in the estuaries of Jiaozhou Bay in North China

Oceanologia, 2020
Summary: Water samples collected from the Jiaozhou Bay every two months between April 2016 and February 2017 were analyzed for dissolved organic carbon (DOC), particulate organic carbon (POC), total dissolved carbohydrates (TCHO), total hydrolyzed amino ...

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 ...
