Source Deghosting by Depth Apparition

Source Deghosting by Depth Apparition

In the  November-December issue of the journal Geophysics we present a new and simple method to remove sea-surface ghosts that is related to the recently introduced concept of signal apparition. As opposed to the temporal/spatial source signature modulation functions used in the original signal apparition theory, our source deghosting method relies on using sources at different depths but not at the same lateral positions.
