The Magellan spacecraft orbited Venus from August 10, 1990, until it plunged into the Venusian atmosphere on October 12, 1994. Magellan Mission objectives included (1) improving the knowledge of the geological processes, surface properties, and geologic history of Venus by analysis of surface radar characteristics , topography, and morphology and (2) improving the knowledge of the geophysics of...

Abstract Understanding the internal structure of specific landforms is a crucial prerequisite for determining their origin and evolution. Near-surface geophysics represents non-invasive way subsurface investigation, it can be used to describe conditions, especially in protected areas. We tested possible hypotheses block accumulations evolution by four different geophysical methods (electrical r...

We study methods for the numerical solution of the Helmholtz equation for twodimensional applications in geophysics. The common framework of the iterative methods in our study is a combination of an inner iteration with a geometric multigrid method used as a preconditioner and an outer iteration with a Krylov subspace method. The preconditioning system is based on either a pure or shifted Helmh...

The history of geophysics in Australia began with the first European explorers, who were concerned with the measurement of basic geophysical quantities, such as the Earth’s gravitational and magnetic fields (Day, 1966). By the first half of the twentieth century, Australia had been recognised as a possible happy-hunting ground for the new methods of exploration geophysics, as witness the accoun...

Hydrogeologists have long been interested in using geophysical measurements to answer questions about the Earth. Originally used to find ore bodies or oil and gas, geophysics’ sensitivity to water was originally considered a nuisance. While looking for metallic ore using electricalinduced polarization, for instance, early geophysicists found that groundwater controlled most of the measured sign...
