Summary:

Trials to assess the behavioural response of free-ranging bottlenose dolphins to continuous and responsive pingers were conducted. In boat based trials both types of pinger affected dolphin behaviour, while in static trials the detection of dolphin vocalisations was significantly lower in the presence of active continuous pingers.
