Using CDOM spectral shape information to improve the estimation of DOC concentration in inland waters: A case study of Andean Patagonian Lakes.

Science of the Total Environment, 2022
For the last two decades different scientific disciplines have focused on lacustrine dissolved organic matter (DOM) given its importance in the biogeochemistry of carbon and in ecosystem functioning.

Remote estimates of CDOM using Sentinel-2 remote sensing data in reservoirs with different trophic states across China.

Journal of Environmental Management, 2021
Chromophoric dissolved organic matter (DOM) is called as CDOM which could affect the optical properties of surface waters, and is a useful parameter for monitoring complex inland aquatic systems.

Mapping lake CDOM by satellite remote sensing

Remote Sensing of Environment, 2005
Abstract Given the importance of coloured dissolved organic matter (CDOM) for the structure and function of lake ecosystems, a method to estimate the amount of CDOM in lake waters over large geographic areas would be highly desirable. Advanced Land Imager (ALI) images were acquired in southern Finland (in 2002) and southern Sweden (in 2003) together ...

Fluorescence spectroscopy of CDOM in urbanized waters across gradients of development/industrialization of China.

Journal of Hazardous Materials, 2021
The optical signature of chromophoric dissolved organic matter (CDOM) has been related to sources and composition of dissolved organic matter (DOM) in surface waters, but the spatial scope of previous research has been limited to single cities with no ...

A highly sensitive in-situ CDOM sensor

2013 IEEE International Conference on Information and Automation (ICIA), 2013
In-situ colored dissolved organic matter (CDOM) detection has great significance for marine scientific research. In this work, we have developed and tested a highly sensitive in-situ CDOM sensor. With the detecting principle and in-situ survey requirement, we have designed the conjugate focus light path, watertight mechanical structure and high ...

Chromophoric dissolved organic matter (CDOM) in the Equatorial Atlantic Ocean: Optical properties and their relation to CDOM structure and source

Marine Chemistry, 2013
Abstract Extensive data exist on the optical properties of CDOM from terrestrial and coastal environments, yet the open oceans have been historically under-sampled. Consequently, the source and structural basis of marine CDOM optical properties are still debated.

Indirect photodegradation of sulfathiazole and sulfamerazine: Influence of the CDOM components and seawater factors (salinity, pH, nitrate and bicarbonate).

Science of the Total Environment, 2020
Sulfonamides (SAs) are ubiquitous antibiotics that are increasingly detected in the aquatic environment, and may cause potential harm to the environment and humans.

CDOM transport from the Bahamas Banks

Coral Reefs, 2004
The transport of colored dissolved organic matter (CDOM) between shallow banks and deep basins in the Bahamas was the focus of this study. Hydrographic and CDOM absorption measurements made on the Bahamas Banks and in Exuma Sound during the spring of 1999 and 2000 showed that values of salinity and CDOM absorption at 440 nm were higher on the banks (37.

Optical properties of chromophoric dissolved organic matter (CDOM) and dissolved organic carbon (DOC) levels in constructed water treatment wetland systems in southern California, USA.

Chemosphere, 2020
Many removal mechanisms in treatment wetlands involve absorption to organic matter. Optical properties and DOC levels of waters entering and exiting 4 treatment wetland systems in Orange County, Southern California, were measured to characterize the ...
