Background information and definitions
Sonar (sound navigation and ranging) may be used for military, civil and scientific applications to navigate, communicate or detect objects underwater. Research suggests that the use of active sonar can have behavioural and physiological effects on marine mammals and can lead to mass stranding events (Frantzis 1998, Jepson et al. 2003, Parsons 2017). Limiting, ceasing or prohibiting the use of underwater sonar may reduce these negative impacts.
