There are many applications of sea-floor topography modelling to 

 the geologic Interpretation of seafloor processes. Deterministic models 

 Illustrate that sea-floor relief Is often decidedly anisotropic. This 

 Investigation will provide Insight into the systematic nature of such 

 spatial patterns and at several scales. Hayes and Conolly (1972) demon- 

 strated the value of spectral techniques in studying the complex topog- 

 raphy of the Australian-Antarctic Discordance. Since many geological 

 processes result in linear features of characteristic wavelengths, an 

 accurate, frequency-dependent, stochastic model could provide the capa- 

 bility of decomposing such features and delineating their geographic 

 distributions. It is anticipated that many important but totally 

 unforeseen relationships will be discovered in exploiting this higher 

 frequency model in the same manner that numerous fundamental relation- 

 ships were discovered through the generation of global bathymetrlc 

 charts.
