Deep-Sea Research Part I: Oceanographic Research Papers, 2014 We analyze a two-year time-series of chromophoric dissolved organic matter (CDOM) light absorption measurements in the upper 400 m of the water column at the BOUSSOLE site in the NW Mediterranean Sea.

The optical properties of chromophoric dissolved organic matter (CDOM) in Danish estuaries and coastal waters were investigated. A new method for estimating the spectral slope coefficient (S) was examined and found to give a closer fit for the measured absorption (92% reduction in sum of residuals) than the traditional method.

CDOM is a ubiquitous component of the dissolved organic matter pool which absorbs UV and visible light. Owing to its optical properties it plays a critical role in photochemistry and biogeochemistry in aquatic systems. Extensive data exist on the optical properties of CDOM from both terrestrial and coastal environments, yet the open oceans have been ...

To explore whether quinone moieties are important in chromophoric dissolved organic matter (CDOM) photochemistry in natural waters, hydrogen peroxide (H2O2) production and associated optical property changes were measured in aqueous solutions irradiated with a Xenon lamp for CDOM model compounds (dihydroquinone, benzoquinone, anthraquinone ...

Here we investigated absorption and fluorescence properties of chromophoric dissolved organic matter (CDOM) in 15 alpine lakes located below or above the tree line to determine its source and composition. The results indicate that the concentrations of CDOM in below-tree-line lakes are significantly higher than in above-tree-line lakes, as evidenced ...

Abstract Chromophoric dissolved organic matter (CDOM) is a key component in aquatic ecosystem. CDOM plays a critical role in water optical attenuation and in biogeochemical processing. In this study the optical absorption properties and spatial distribution of CDOM were investigated during the wet season in Poyang Lake.

The carbon contained as dissolved organic matter (DOM) in the Earth’s oceans is an important factor in the global carbon cycle, but studying and tracking DOM in the aquatic environment can be challenging. However, the light-absorbing and emitting subcomponents of DOM, called chromophoric dissolved organic matter (CDOM) and fluorescent dissolved organic

Doubtful Sound, Fiordland National Park, New Zealand has a stable low salinity layer (LSL) at the surface due to the high annual rainfall and an additional freshwater input from the discharge of a hydroelectric power plant. Chromophoric dissolved organic matter (CDOM) distribution dynamics in this LSL were analyzed using Excitation Emission Matrix (EEM)

The concentration of dissolved organic carbon (DOC) in some rivers in the western Sichuan Plateau is extremely high. Due to the unique optical properties of colored dissolved organic matter (CDOM), a thorough understanding of the photodegradation characteristics of CDOM helps in revealing regional DOC dynamics and carbon cycle at the water-land ...
