Background information and definitions
Airguns used for seismic surveys produce high intensity sounds that may disturb or cause auditory injury to marine and freshwater mammals (Gordon et al. 2003). Using alternative ‘quieter’ methods instead of airguns for seismic surveys may reduce these impacts. For example, a method called marine vibroseis, which uses lower intensity sounds over a longer duration, may reduce some of the impacts on marine mammals (Richardson & Ellison 2013).
