Paper Abstract

The spectral fluorescence efficiency function ((eta) ((lambda) x,(lambda) m) equals quanta fluoresced per nm interval of (lambda) m per quanta absorbed at (lambda) x, (lambda) x equals excitation wavelength, (lambda) m equals emission wavelength) has been determined for several different fulvic and humic acid samples, and the 3-dimensional surfaces have been described mathematically. These data are used along with a published two-flow irradiance model to calculate the effect of solar-stimulated fluorescence due to colored dissolved organic matter (CDOM; also gelbstoff) on irradiance reflectance just below the sea surface along a transect taken on the West Florida Shelf. In addition, a strategy is suggested for using (eta) ((lambda) x,(lambda) m) and mass-specific absorption coefficient measurements of CDOM to determine CDOM concentrations from remotely sensed fluorescence measurements.
