Abstract
Editorial: Linking Optical and Chemical Properties of Dissolved Organic Matter in Natural Waters
Highlights
First described as “gelbstoff ” or the yellow color in coastal waters, CDOM plays a key role in the ocean’s carbon cycle through its absorption of sunlight, which results in an alteration of the underwater light field via contributing to light attenuation in the water column as well the potential for a variety of photochemical reactions to occur which can influence the redox chemistry of seawater and—via photooxidation—lead to the generation of carbon dioxide (CO2) from Dissolved organic matter (DOM) (Coble, 2007)
Multiple emission spectra measured at discrete wavelengths are concatenated into 3D excitation-emission matrices (EEMs), which for a sample may be visualized as a contour plot
The global view of CDOM absorbance and fluorescence in the oceans was given by Nelson and Gauglitz
Summary
Linking Optical and Chemical Properties of Dissolved Organic Matter in Natural Waters Developing this analysis in coastal shelves, Fichot et al explore relationships between lignin reactivity and identify key lignin-phenol groups responsible for largest variability, and note lignin is one of many terrestrial and planktonic sources of CDOM absorbance in natural waters.
