Effects of Biological and Photochemical Degradation on the Optical Properties of CDOM Exported to Coastal Marine Environments
Abstract
Dissolved organic matter (DOM) exported from rivers and intertidal marshes to coastal oceans typically contains high concentrations of light-absorbing molecules that can interfere with remote sensing of ocean color. This project quantitatively assessed the ability of coastal ocean bacteria to degrade and produce CDOM and investigated the synergistic interactions between bacterial degradation and photochemical processes in transforming CDOM in seawater and altering its optical properties. Optical properties (absorption spectra, EEMs), photoreactivity and biological lability of CDOM formed during the bacterial degradation of selected vascular plants and algae was used to asses the relative importance of terrestrial and marine organic matter as sources of CDOM.
