The term swell filter in high resolution seismics (reflection seismology) or sub bottom profiling refers to the static correction that restores the coherence of a high resolution seismic profile. The coherence of the image got lost because of the relative movement (a function of the wavelength of the signal and the swell) of the source and receiver during the recording. In normal seismic recordings, the term swell filter refers to filtering the acoustic noise, created by waves, out of the seismic recording.

Famous quotes containing the word swell:
“Let a man find himself, in distinction from others, on top of two wheels with a chain—at least in a poor country like Russia—and his vanity begins to swell out like his tyres. In America it takes an automobile to produce this effect.”
—Leon Trotsky (1879–1940)
