Data from: Vessel noise levels drive behavioural responses of humpback whales with implications for whale-watching ...
Disturbance from whale-watching can cause significant behavioural changes with fitness consequences for targeted whale populations. However, the sensory stimuli triggering these responses are unknown, preventing effective mitigation. Here, we test the hypothesis that vessel noise level is a driver o...
