Abstract:

The principal long-term objective of this work is to determine what factors control the distribution and dynamics of the chromophore-containing constituents of dissolved organic matter CDOM in marine and estuarine waters. Two important secondary objectives are 1 to elucidate the photochemical properties of the CDOM and how photochemical reactions affect the optical properties and secondary reactivity of the CDOM, 2 to obtain a clearer understanding of the nature of the underlying light-absorbing constituents that produce the absorption spectrum of the CDOM. Field measurements are employed to determine the distribution of CDOM and its impact on the aquatic light field, whereas a combination of field and laboratory experiments are used to test mechanisms of its formation and loss.
