Application of the Wavelet Transform to Isostatic Analyses in Australia. Existing methods of determining the Earth's isostatic response assume ideal but unrealistic conditions. This project will develop a new technique for isostatic analysis, using the two-dimensional wavelet transform. This tool can resolve spectral components of geophysical data in the space domain, thus avoiding the problems arising during the conventional Fourier analysis.

Existing methods of determining the Earth's isostatic response assume ideal but unrealistic conditions. This project will develop a new technique for isostatic analysis, using the two-dimensional wavelet transform. This tool can resolve spectral components of geophysical data in the space domain, thus avoiding the problems arising during the conventional Fourier analysis. With innovative processing methods, maps of the crustal thickness from gravity and topography data can be generated, a task usually reserved for costly seismic experiments. Analysis of the wavelet power spectrum would also benefit the exploration industry by identifying previously unknown sedimentary basins.Read moreRead less
