Processes Affecting the Variability of Fluorescence Signals from Benthic Targets in Shallow Waters
1998
Falkowski, Paul G.
Our major theme is to understand and to qualify processes that contribute to fluorescence emission from benthic targets in the coastal and shallow waters with the overarching goal of developing parameterization schemes that optically detect anthropogenic objects. Our scientific objectives are: 1. To identify the sources of variations in the effective absorption cross sections of the target molecules, fluorescence lifetimes (and by inference, quantum yields) of individual chromophores, and to provide an interpretive understanding of how physical, chemical, and biological variability affects these optical properties. 2. To determine the extent and variability in the coupling of absorbed radiation to the fluorescence emission spectrum, and the development of biophysical radiative transfer models that predict the latter from the former in a variety of benthic environments. 3. To develop an understanding of the spatial and temporal variability in benthic and optical signals.
