Notes:
The shallowest few hundred metres of the earth cannot be adequately imaged by conventional seismic when tuned for deeper targets. Adding independent measurements (such as uphole or shallow refraction surveys) reduces this information gap, but in some arid areas (such as Saudi Arabia) the near-surface complexities are not well resolved, even in this way. The joint tomographic inversion of different wave types can contribute to reducing these ambiguities further, by complementing the different penetration ranges and propagation directions of reflected, refracted and diving waves. Here, we demonstrate the weakness of diving waves when used alone, and the value of complementing them by available reflected and refracted arrivals.
