| Abstract: | Fractal analysis has been carried out for gravity and bathymetry profiles to examine the nature of the short wavelength irregularities of the profiles which are not generally explained by the linear models of ocean floor evolution. The Iterated Function System has been used to generate synthetic profiles of known dimensions and these are compared with the observed profiles. The results show that the fractal dimensions for the data sets are in the range of 1.24-1.49. It is observed that the fractal dimensions for the gravity profiles are lesser than those of the bathymetry. The fractal dimensions for bathymetry and gravity over spreading ridge are higher than those for the aseismic ridge. The fractal nature is related to the chaotic behavior of dynamical systems which though unpredictable are not random. The fractal dimensions obtained from the present analysis show that the systems generating the signals can be represented by a dynamical system of low order. |
