Enhanced Estimate of Chromophoric Dissolved Organic Matter Using Machine Learning Algorithms from Landsat-8 OLI Data in the Pearl River Estuary

Remote Sensing, 2023
Chromophoric Dissolved Organic Matter (CDOM) plays a critical role in the carbon and biogeochemical cycles within aquatic ecosystems. Satellite imagery can be employed to determine aquatic CDOM concentrations, highlighting the need for effective and ...

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 ...

Chromophoric dissolved organic matter dynamics revealed through the optimization of an optical–biogeochemical model in the northwestern Mediterranean Sea

Biogeosciences, 2023
. Chromophoric dissolved organic matter (CDOM) significantly contributes to the non-water absorption budget in the Mediterranean Sea. The absorption coefficient of CDOM, aCDOM(λ), is measurable in situ and can be retrieved remotely, although ocean-colour

Characteristics of chromophoric dissolved organic matter in the Northern Andaman Sea

Frontiers in Marine Science, 2023
The dissolved organic matter (DOM) in the ocean is a large carbon pool that plays an important role in the global carbon cycle. Investigation of the characteristics and behaviors of DOM in some areas facilitates a better understanding of biochemical ...

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

Statistical Optimization of Vegetable Washwater Treatment Using Electrocoagulation. [PDF]

Water Environ Res
Optimized electrocoagulation (0.32 A, 8.8 min, aluminum electrode) effectively removes suspended solids, turbidity, and COD from four types of raw vegetable washwaters. This provides a simple, robust solution for treating and reusing these agricultural effluents.

Photochemical and Microbial Degradation of Chromophoric Dissolved Organic Matter Exported From Tidal Marshes

Journal of Geophysical Research: Biogeosciences, 2021
Wetlands export chromophoric dissolved organic matter (CDOM) to estuaries, where CDOM is removed and transformed through biotic and abiotic process, subsequently impacting nutrient cycling, light availability, ecosystem metabolism, and phytoplankton ...
