List of top Geology and Geophysics Questions on Seismic Data Processing asked in GATE GG

A stacked seismic section shows a single dipping event with a slope of \(0.5\ \text{s/km}\). Stolt migration with a constant velocity of \(2\ \text{km/s}\) is applied to the data. The dip of the event in the migrated section in degrees is __________ (rounded off to one decimal place).
A marine seismic survey was performed in a region with a flat, horizontal sea bed at a depth of 100 m from the sea surface. The datum of the stacked seismic section was fixed at the sea surface. If the P-wave velocity in water is \(1600\ \text{m/s}\), the radius of the first Fresnel zone at the sea bed at a frequency of \(50\ \text{Hz}\) corresponding to the stacked seismic section is _________ (rounded off to one decimal place).
