Near-surface statics are corrections for traveltime variations caused by the extremely strong lateral variation of the seismic velocity field near the surface of the Earth. The statics act like a smear on a glass window, distorting the seismic image of deeper structures. Correction for near-surface statics is among the major challenges for onshore and near-shore seismic processing. One promising remedy is tomostatics, which determines the near-surface static contribution to reflection seismic data based on velocity models derived from traveltime tomography.
