%X While processing samples collected from coastal waters of Qingdao for algae cell density and species identification during the termination stage of a red tide event, we obtained a set of three-dimensional excitation emission matrix fluorescence spectra on filtered water samples. The results showed that 1) the wavelength with the highest excitation intensity was 245 nm, and the that with the highest emission intensity was 445 nm. The transitional wavelength for the excitation spectrum was 260 nm, and that for the emission spectrum was 245 nm when cell density in seawater was near or reached the density of typical red tide, 2) in the non-red tide area, the wavelength with the highest excitation intensity (235 nm) was lower than that in the red tide area, whereas the wavelength with the highest emission intensity was slightly higher, and the transitional excitation and emission fluorescent wavelengths in the non-red tide area were both higher than those in the red tide area, 3) when the excitation wavelength was less or equal to 260 nm, 84.78% of emission wavelengths were higher than the exciting wavelengths; and when the excitation wavelength was higher than 260nm, only 15.22% of emission wavelengths were higher than the exciting wavelengths, 4) when the excitation wavelength was 410 nm, the emission wavelength was equal to the excitation wavelength, 5) the density of Skeleconema costatum showed significant correlation with the exponential value of the excitation and emission intensity ratio.
