Abstract: Picking the seismic arrival time is an important parameter for the refraction studies. However, random noise, mainly generated by unknown sources, leads to the data quality reduction and incorrect arrival definition. Besides, picking the accurate… read more here.

Abstract: Abstract We present a 3-D cross-gradient joint inversion algorithm for seismic refraction and DC resistivity data. The structural similarity between seismic slowness and resistivity models is enforced by a cross-gradient term in the objective function… read more here.
