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:
“Draw up the dew. Swell with pacific violence.
Take shape in silence. Grow as the clouds grew.
Beautiful brood the cornlands, and you are heavy;
Leafy the boughs—they also hide big fruit.”
—Cecil Day Lewis (1904–1972)
