English term or phrase: vibroseis

Definition from Wikipedia:
Vibroseis is a method used to propagate energy signals into the earth over an extended period of time as opposed to the near instantaneous energy provided by impulsive sources. The data recorded in this way must be correlated to convert the extended source signal into an impulse. The source signal using this method was originally generated by a servo-controlled hydraulic vibrator or shaker unit mounted on a mobile base unit, but electro-mechanical versions have also been developed.

Example sentence(s):

Vibroseis is a method that imparts coded seismic energy into the ground. The energy is recorded with geophones and then processed using the known (coded) input signal. The resulting time-domain representation of vibroseis data is an impulsive wavetrain with wavelet properties consistent with the coded input signal convolved with the earth's reflectivity series.

As the demand for high-density and wide-azimuth data increases, HPVA enables high-performance vibroseis crews to increase survey specifications whilst maintaining high production rates and data quality. CGG Veritas
Computer processing of the seismic signals from a vibroseis source uses the distinct characteristics of the sweep to "collapse" the energy into short duration wavelets—essentially equivalent to the seismograms that would be recorded with impulsive sources such as explosives. Carleton College

vibroseis

Definition from wordlingo:
Vibroseis is een methode die wordt gebruikt om energiesignalen in te verspreiden aarde over een uitgebreide tijdspanne in tegenstelling tot de dichtbijgelegen onmiddellijke energie die door impulsieve bronnen wordt verstrekt. De op deze wijze geregistreerde gegevens moeten zijn gecorreleerd om het uitgebreide bronsignaal in een impuls om te zetten. Het bronsignaal dat deze methode gebruikt werd oorspronkelijk geproduceerd door een servo-controlled hydraulische vibrator of schudbeker eenheid opgezet op een mobiele basiseenheid, maar elektromechanisch de versies zijn ook ontwikkeld.

Example sentence(s):

"Vibroseis werd ontwikkeld door Continentale Oliemaatschappij (Conoco) tijdens de jaren '50 en was een handelsmerk tot het bedrijf octrooi verstreken." - worldlingo
"Voor praktische toepassingen van de Vibroseis methode dient de geïntegreerde tractie onder de plaat (gelijk aan minus de "ground force") bepaald te worden uit metingen van de versnellingen van bodemplaat en reaktie massa." (pg 270) - TU Delft
