Spectral Analysis

Energy spectra in geophysics : biology

(a) : Salinity power spectra, (b) : Fluorescence power spectra [Seuront, 1999]InformationInformation[1]

The PSD is used not only to characterize the physical processes but also to provide some information about the biological fields. The figures (a,b) show that the salinity and the fluorescence field have the scaling invariance propriety.
