Abstract : Our long-term goal is to interprete chromophoric dissolved organic matter (CDOM) sources, distributions, and dynamics in and around the NY/NJ Harbor Estuary, with a focus on significant freshwater events, through the creation of a robust, deterministic, high-resolution, four-dimensional, predictive model of CDOM fate and transport, validated

[Spatial Distribution and Degradation of CDOM in the Minjiang River in Summer].
Huan jing ke xue= Huanjing kexue, 2019The composition, distribution, and degradation of chromophoric dissolved organic matter (CDOM) in the lower reach and estuary of the Minjiang River were analyzed using fluorescence excitation-emission matrices-parallel factor analysis (EEMs-PARAFAC) and microbial and photochemical degradation experiments.

Journal of Geophysical Research: Oceans, 2012
Absorption coefficients of colored dissolved organic matter (CDOM) were measured together with salinity, δ18O, and inorganic nutrients across the Fram Strait. A pronounced CDOM absorption maximum between 30 and 120 m depth was associated with river and sea ice brine enriched water, characteristic of the Arctic mixed layer and upper halocline waters in ...

A temperature calibration method for CDOM fluorescence LIF LiDAR
SPIE Proceedings, 2016The influence of temperature variations on the determined concentrations of dissolved organic matter (DOM) in water was investigated by laser induced fluorescence (LIF) technique in laboratory. The effect of temperature on CDOM fluorescence was investigated in freshwaters of Xixi River and in aqueous standards.

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

Retrieval of hyperspectral CDOM absorption with integrating cavity sphere
2020<p>Typical measurements of the absorption coefficient of the chromophoric fraction of dissolved organic carbon (CDOM) are performed on filtered seawaters samples. Though samples could be stored in the dark at 4&#176; for up to 6 months, it is preferable to analyse them within 24 hours from collection as variation of ...

Photobleaching of chromophoric dissolved organic matter (CDOM) in rainwater
Journal of Atmospheric Chemistry, 2007Significant photodegradation of chromophoric dissolved organic matter (CDOM) in rainwater was observed after exposure to simulated sunlight. Fluorescence excitation emission spectra (EEMS) of precipitation revealed the presence of four major peaks all of which degraded upon photolysis with the greatest loss in the region characteristic of marine CDOM ...

[Construction and application of an onboard absorption analyzer device for CDOM].
Guang pu xue yu guang pu fen xi = Guang pu, 2014Colored dissolved organic matter (CDOM) plays an important role in marine ecosystems. In order to solve the current problems in measurement of CDOM absorption, an automated onboard analyzer based on liquid core waveguides (Teflon AF LWCC/LCW) was constructed.

Variability of CDOM in dependence of lake hydrology and stratification
2019The samples were collected during spring flooding conditions in temperate, stratified floodplain lake Sakadaš in the Kopački Rit floodplain of the River Danube. A selection of environmental (Danube water level, lake water depth, transparency, water and air temperature, pH, conductivity, ammonium, nitrites, nitrates, Kjeldahl nitrogen, total phosphorus ...
