A seismic refraction survey records, along a line of receivers, the first arrivals from a controlled source, and uses the head waves that travel along the top of faster layers to find their speeds and depths. A seismic reflection survey records the whole wave train, at offsets mostly smaller than the depths of interest, and uses the waves reflected at near-normal incidence by the interfaces to image the layering.
