Responses of cetaceans to anthropogenic noise
TL;DR: In this paper, a review of the effects of anthropogenic noise on cetaceans has been published and their ability to document response(s), or the lack thereof, has improved.

TL;DR: Reduced ship traffic in the Bay of Fundy, Canada, following the events of 11 September 2001, resulted in a 6 dB decrease in underwater noise with a significant reduction below 150 Hz, which is the first evidence that exposure to low-frequency ship noise may be associated with chronic stress in whales.

TL;DR: The survival of North Atlantic right whales (Eubalaena glacialis) is seriously threatened by mortality caused by ships and entanglements in fishing gear as discussed by the authors. But despite efforts to reduce anthropogenic mortalities, and in spite of recent increases in calving, the survival of right whales is still threatened.
Journal ArticleDOI
Individual right whales call louder in increased environmental noise.
TL;DR: Changes in calling behaviour by individual endangered North Atlantic right whales in increased background noise are documented, affecting both the way whales use sound to communicate and the ability to detect them with passive acoustic monitoring systems.
Journal ArticleDOI
North Atlantic right whales (Eubalaena glacialis) ignore ships but respond to alerting stimuli.
TL;DR: A multi–sensor acoustic recording tag was used to measure the responses of whales to passing ships and experimentally tested their responses to controlled sound exposures, which included recordings of ship noise, the social sounds of conspecifics and a signal designed to alert the whales.
