SEG Distinguished Lecturer: Imaging the Earth's near Surface: The why and how of applied Geophysics for the 21st Century

The top few kilometres of the Earth's surface are of extreme importance to our society. This near-surface region houses mineral and hydrocarbon wealth that are crucial for industrialized development, contains water needed for life, and is an environment with which we must interact to build our infrastructure. Substantial insight about the structure and composition of this region can be gleaned by determining its physical properties. Density,magnetic susceptibility, electrical conductivity, and elastic parameters can be critically diagnostic and data from appropriate geophysical survey can be inverted to generated 3D distribution of these.
