Time Series Analysis of Chromophoric Dissolved Organic Matter (CDOM) at Perancak Estuary

International Journal of Natural Science and Engineering, 2023
This study aimed at determaining the effect of sea tides on  changes of CDOM,  in-situ parameters and  nutrients on Perancak Estuary. The subject of  this study was estuary water collected from Estuary Perancak and filtered using GF/F 0.7 μm with help of injection.

Chromophoric dissolved organic matter (CDOM) in a subtropical estuary (Galveston Bay, USA) and the impact of Hurricane Harvey

Environmental Science and Pollution Research, 2021
The landfall of Hurricane Harvey in August 2017 provided the opportunity to study the impact of extreme freshwater discharge on chromophoric dissolved organic matter (CDOM) properties in a subtropical estuary (Galveston Bay, Texas). Both fluorescence spectroscopy (excitation-emission matrices) and a three-component parallel factor analysis (PARAFAC ...

Estimating of chromophoric dissolved organic matter (CDOM) with in-situ and satellite hyperspectral remote sensing technology

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The influence of land surface characteristics and climate conditions on the source, quantity, quality, and timing of dissolved organic carbon (DOC) fluxes to coastal waters is not well understood. The significant correlation between DOC and chromophoric dissolved organic matter (CDOM) leads to an increasing need of CDOM monitoring for understanding the

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.

Optical Properties and Signatures of Chromophoric Dissolved Organic Matter (CDOM) in Danish Coastal Waters

Estuarine, Coastal and Shelf Science, 2000
The optical properties of chromophoric dissolved organic matter (CDOM) in Danish estuaries and coastal waters were investigated. A new method for estimating the spectral slope coefficient (S) was examined and found to give a closer fit for the measured absorption (92% reduction in sum of residuals) than the traditional method.

CHROMOPHORIC DISSOLVED ORGANIC MATTER (CDOM) IN THE OCEAN: OPTICAL PROPERTIES AND RELATION TO CDOM STRUCTURE AND SOURCE

2014
CDOM is a ubiquitous component of the dissolved organic matter pool which absorbs UV and visible light. Owing to its optical properties it plays a critical role in photochemistry and biogeochemistry in aquatic systems. Extensive data exist on the optical properties of CDOM from both terrestrial and coastal environments, yet the open oceans have been ...

Photoproduction of hydrogen peroxide in aqueous solution from model compounds for chromophoric dissolved organic matter (CDOM)

Marine Pollution Bulletin, 2014
To explore whether quinone moieties are important in chromophoric dissolved organic matter (CDOM) photochemistry in natural waters, hydrogen peroxide (H2O2) production and associated optical property changes were measured in aqueous solutions irradiated with a Xenon lamp for CDOM model compounds (dihydroquinone, benzoquinone, anthraquinone ...
