Marine guided waves are strongly dispersive and commonly observed in seismic surveys worldwide in areas of shallow water with a hard seafloor. They are energetic and can obscure deeper reflection signals. We have conducted several ultrasonic physical

Some ocean bottom seismic records from Western Australia show very low frequency noise amplitudes that are larger than peak-to-peak amplitudes of seismic reflections on hydrophone records. The noise period is longer than a 5000 ms record length. As a

Transformer coupled hydrophones are generally paired with matching geophones. It can be shown that as a result of the natural life cycle of a hydrophone sensor unit, there can be rather large frequency dependent variations that exceed 12 dB in sensit

In February, 2015, after many years of research, preparation and testing, Geokinetics conducted the first production seismic acquisition using a marine vibrator that the industry has seen in nearly 15 years. The marine vibrator, the AquaVib, is the r

In the November 2016 President's Page, Past President John Bradford highlighted the challenges SEG needs to address: we need to broaden our base, we need to do a better job of retaining members as they make the transition from student to professional

Relative entropy normalization of the spiking deconvolution filter is recommended because it is relatively insensitive to both the noise power on the input traces and the signal power within the derive gate. Relative entropy normalization scales the

Summary Wave equation migration plays an increasingly important role in seismic data processing. For our purposes we are only considering the one-way wave equation, because of its efficiency. Currently the predominant one-way propagators are FFD and
