AB: The WFS is a complex subtropical coastal region affected by multiple river systems. In recent years, the southern portion of the shelf has been the focus of much study due to the initiation of persistent harmful algal blooms. During this time, great effort has been put forth in collecting seasonal measurements of CDOM (Colored Dissolved Organic Matter) inherent optical properties via in situ and discrete sampling techniques. This sizeable dataset now allows for establishing robust regional relationships of CDOM fluorescence and absorption. Discussed here will be factors affecting that relationship and how it covaries with chlorophyll and DOC (Dissolve Organic Carbon). This relationship also demonstrates the potential for using in situ CDOM fluorescence measurements from moored locations to provide reliable CDOM absorption values for current bio-optical models.
