Data from: The behavioural response of migrating humpback whales to a full seismic air gun array
Despite concerns on the effects of noise from seismic survey air guns on marine organisms, there remains uncertainty in the biological significance of any response.

Despite concerns on the effects of noise from seismic survey air guns on marine organisms, there remains uncertainty in the biological significance of any response. This study quantifies and interprets the response of migrating humpback whales (Megaptera novaeangliae) to a 3130 cui (51.3l) commercial air gun array. We compare the behavioural responses to active trials (array operational; n = 34 whale groups), with responses to control trials (source vessel towing the array while silent; n = 33) and baseline studies of normal behaviour in the absence of the vessel (n = 85). No abnormal behaviours were recorded during the trials. However, in response to the active seismic array and the controls, the whales displayed changes in behaviour.
