Dissolved organic carbon and chromophoric dissolved organic matter properties of rivers in the USA
Journal of Geophysical Research, 2012Dissolved organic carbon (DOC) concentration and chromophoric dissolved organic matter (CDOM) parameters were measured over a range of discharge in 30 U.S. rivers, covering a diverse assortment of fluvial ecosystems in terms of watershed size and landscape drained.

Effects of Ionic Strength on the Chromophores of Dissolved Organic Matter
Environmental Science & Technology, 2015This study examined effects of variations of the ionic strength (IS) on the absorbance of dissolved organic matter (DOM). The measurements performed for DOM of allochthonous (Suwannee River humic and fulvic acids, SRHA and SRFA) and autochthonous (Pony Lake fulvic acid, PLFA) origin showed that increases of IS (which was controlled by additions of ...

The Global Distribution and Dynamics of Chromophoric Dissolved Organic Matter
Annual Review of Marine Science, 2013Chromophoric dissolved organic matter (CDOM) is a ubiquitous component of the open ocean dissolved matter pool, and is important owing to its influence on the optical properties of the water column, its role in photochemistry and photobiology, and its utility as a tracer of deep ocean biogeochemical processes and circulation.

Chromophoric dissolved organic matter and dissolved organic carbon in Chesapeake Bay
Marine Chemistry, 2002Chromophoric dissolved organic matter (CDOM) is the light absorbing fraction of dissolved organic carbon (DOC). The optical properties of CDOM potentially permit remote sensing of DOC and CDOM, and correction for CDOM absorption is essential for remote sensing of chlorophyll a (chl a) in coastal and estuarine waters.

A Multicomponent Model of Chromophoric Dissolved Organic Matter Photobleaching¶§
Photochemistry and Photobiology, 2004ABSTRACTLight absorption by chromophoric dissolved organic matter (CDOM) plays a number of roles in natural waters, including both control of the underwater light field and the initiation of many photochemical reactions. A multicomponent analysis was used to describe the effects of UV and visible radiation on the optical absorption spectra of two ...

Science of The Total Environment, 2023
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

Chemical characteristics of chromophoric dissolved organic matter in rainwater
Atmospheric Environment, 2009Abstract Proton nuclear magnetic resonance (1H-NMR), UV absorbance and excitation-emission matrix (EEM) fluorescence spectroscopy were used to define the chemical characteristics of chromophoric dissolved organic matter (CDOM) in whole and C18 extracted rainwater.

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.
