This study investigates the coupling between Chromophoric Dissolved Organic Matter (CDOM) and Dissolved Inorganic Carbon (DIC) in eighteen Indian estuaries across salinity gradient of the east and west coasts during the monsoon season, characterized by significant river discharge. The hypothesis that humic acids (HA) and fulvic acids (FA), prominent in

Impacts of haze on the photobleaching of chromophoric dissolved organic matter in surface water
Environmental Research, 2022Sunlight plays an important role in the photochemical processes of chromophoric dissolved organic matter (CDOM), which is closely related to water self-purification and primary productivity of healthy aquatic ecosystem health. The fine particles of haze, a widespread air pollutant, absorb natural ultraviolet (UV) irradiation and have an unknown degree ...

Inversion of Chromophoric Dissolved Organic Matter Using Sparse Regression
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Chromophoric dissolved organic matter (CDOM) retrieval remains to be a challenging task in water color remote sensing research due to its highly spatial and temporal variability. In this paper, we present a novel CDOM retrieval algorithm that takes advantage of the sparse learning, which can simultaneously perform feature selection and parameter ...

Contaminant-mediated photobleaching of wetland chromophoric dissolved organic matter
Environ. Sci.: Processes Impacts, 2014Organic contaminants in wetlands undergo indirect photodegradation in the presence of chromophoric dissolved organic matter (CDOM), and in turn can mediate the photobleaching of CDOM.

The Delivery of Chromophoric Dissolved Organic Matter to the Sea
2001Abstract : The long-term goal of this research is to better understand the biogeochemical cycling of dissolved organic matter (DOM) in coastal waters. Of particular interest is the fate of terrigenous and dissolved organic matter in coastal marine systems and its affects on ocean color.

Water Research, 2015
The binding of Ca(2+) and Cu(2+) by dissolved organic matter (DOM) exemplified by Suwannee River Humic Acid (SRHA) was examined in this study. Metal-DOM interactions were quantified using linear and log-transformed DOM absorbance spectra acquired at varying pHs and total Ca(2+) and Cu(2+) concentrations. The binding of Cu(2+) by DOM was examined in the

A Chromophoric Dissolved Organic Matter (CDOM) Observatory
2010Abstract : The long-term goal of this project is to develop an understanding of coastal systems such that optical properties of complex coastal waters can be retrieved and predicted from remote sensing and modeling efforts. This project focuses on establishing a moderate-scale observatory to develop watershed and coastal ocean models and remote sensing

Formation of planktonic chromophoric dissolved organic matter in the ocean
Marine Chemistry, 2019Abstract Chromophoric dissolved organic matter (CDOM) is an important fraction of the marine carbon cycle that controls most light absorption and many photochemical and biological processes in the ocean. Despite its importance, the chemical basis for the formation of oceanic CDOM remains unclear.

Phototransformation of Lignin-related Compounds in Chromophoric Dissolved Organic Matter Solutions
Water Research, 2023Lignin is a major terrestrial source of chromophoric dissolved organic matter (CDOM), and studying the phototransformation of lignin monomers and their related compounds can enhance our understanding of CDOM intramolecular interactions. Coniferyl aldehyde (Coni) and sinapaldehyde (Sina) form ground-state complexes with CDOM, with equilibrium constants ...

Modeling the spectral shape of absorption by chromophoric dissolved organic matter
Marine Chemistry, 2004 A single exponential model of the form a g (λ)αe -s c λ was evaluated in the context of its application and interpretation in describing absorption by chromophoric dissolved organic matter (CDOM), a g , as a function of wavelength, λ. The spectral slope, s e , is often used as a proxy for CDOM composition, including the ratio of fulvic to humic acids ...
