Abstract:

The long-term goal of this project is to determine sources, sinks and dynamics of Colored Dissolved Organic Matter CDOM optical properties on spatial and temporal scales relevant to physicalbiogeochemicaloptical modeling efforts on the West Florida Shelf. Predictive capability is needed for modeling in-water light attenuation and visibility in coastal regions. CDOM is one of the most significant and least understood light attenuating components, hence improved understanding of its optical properties, dynamics and spatial and temporal variability will result in improved radiance models in the littoral zone. The short-term goals are to characterize spatial and temporal variability in optical properties by determining sources and sinks of CDOM and Dissolved Organic Carbon DOC for the West Florida Shelf. The loss of CDOM by dilutionphysical mixing and photobleaching will also be investigated. Photodegradation rates and effects of sunlight on CDOM optical properties and CDOCDOC relationship as a function of CDOM source will be determined. This information will be applied to bio-optical and predictive light field models.
