Paper Summary
The frequency content and the temporal resolution of marine seismic data acquired using conventional constant-depth streamer is affected by the interference from the reflections at the sea surface in both source and receiver sides. The interference by the slightly delayed reflections trailing the original source wavelet, called ghosts, can be either constructive or destructive for different wavelengths. The resulting wavelet may contain a number of notches in the amplitude spectrum, accompanied with drastic variations in the phase spectrum.
