WebCDOM is the colored dissolved organic matter. What makes the fresh water higher in CDOM concentrations than the ocean? ... This could be a potential reason that estuary generally have lower CDOM ... WebFeb 1, 2024 · While, the CDOM in the most waters had a HIX of <4, suggesting a biological or aquatic bacterial origin of DOM. Interestingly, the HIX value in the deep water was relatively large with a mean value of 6.42 ± 3.32. Thus, the degree of CDOM humification in the deepsea water was higher than that in the surface and subsurface water.

Colored Dissolved Organic Matter (CDOM) - Remote Sensing of …

WebIn this study, we analyze interactions in lake and lake catchment systems of a continuous permafrost area. We assessed colored dissolved organic matter (CDOM) absorption at 440 nm (a(440)CDOM) and absorption slope (S300–500) in lakes using field sampling and optical remote sensing data for an area of 350 km2 in Central Yamal, Siberia. Applying a … WebJul 23, 2014 · The development of techniques for real-time monitoring of water quality is of great importance for effectively managing inland water resources. In this study, we first analyzed the absorption and fluorescence properties in a large subtropical reservoir and then used a chromophoric dissolved organic matter (CDOM) fluorescence monitoring … comprehensive cancer center southern hills

WebCDOM corresponds to total organic carbon, which is an indicator of discharge water quality. It is a compact and highly sensitive fluorometer with excellent turbidity rejection and high ambient light rejection, making it suitable for use in water and wastewater treatment works, as well as natural waters at the surface and to depths of up to 1000 m. WebFeb 16, 2024 · The absorption spectrum of CDOM (A CDOM (λ), unitless) can be described by an exponential function that decays with increasing wavelength: A CDOM (λ) = 100 d DOC A o e − S λ, where d [m] is water depth, DOC [mg C L −1] is dissolved organic carbon, A o [L mg C −1 cm −1] is a pre-exponential factor, and S [nm −1] is the spectral slope. Webwater. DOM, and especially CDOM, increases the consumption of water treatment chemicals, reacts with chlorine to form potentially harmful disinfection by-products, stimulates bacterial growth, and fouls filtration membranes. CDOM is easily measured in the lab on a filtered water sample as the absorbance, Aλ echo current user windows
