A Marine Seismic Source with Enhanced Low and Reduced High Frequency Content

We describe the physical principles underlying a new type of marine seismic source, the so-called Tuned Pulse Source and show that it generates more low frequency and less spurious high frequency content than conventional airgun arrays. The enhanced low frequency content is attractive for seismic exploration. The reduced high frequency content leads to a lower environmental impact. We show measurements on a prototype of such a source and model its relevance for Full Waveform Inversion.
