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:
“If any mention was made of homicide, madness, adultery, and intolerable tortures, we would let the church-bells ring louder, the church-organ swell its peal and drown the hideous sound. The sugar they raised was excellent: nobody tasted blood in it.”
—Ralph Waldo Emerson (1803–1882)
