In this E-Lecture: Gary Hampson, Principal Research Geophysicist at DownUnder Geosolutions, will explain an extension to the airgun Notional Source concept called Notional Ghosts. These are conceptual devices that describe the source ghost in terms of
virtual monopole sources each of which has its own signature. As with notional sources, although notional ghosts are never directly observed, they are derived by inversion of the pressure wavefield recorded by the near field hydrophones. In this lecture
Gary explains the motivation for this new concept, its theoretical basis and shows real examples.
