Chromophoric dissolved organic matter in inland waters: Present knowledge and future challenges

open access: yesScience of the Total Environment, 2021
Chromophoric dissolved organic matter (CDOM) plays an important role in the biogeochemical cycle and energy flow of aquatic ecosystems. Thus, systematic and comprehensive understanding of CDOM dynamics is critically important for aquatic ecosystem management. CDOM spans multiple study fields, including analytical chemistry, biogeochemistry, water color

Dissolved organic carbon and chromophoric dissolved organic matter properties of rivers in the USA

Journal of Geophysical Research G: Biogeosciences, 2012
Dissolved 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, 2015
This 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, 2013
Chromophoric 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, 2002
Chromophoric 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, 2004
ABSTRACTLight 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 ...
