The Whale Trail
Tonquin Trail, Tofino

JASCO has collaborated with the Vancouver Aquarium to bring you the following marine mammal vocalizations. The Land-Based Whale Watching project, known as The Whale Trail, is an initiative that supports on-shore locations from which the public can see orcas and other marine mammals and report their sightings to the B.C. Cetacean Sightings Network.

Marine Mammal Sounds

Grey Whale
Eschrichtius robustus

To make the grey whale calls audible, the audio file is sped up 7 times faster than normal.

Humpback Whale
Megaptera novaeangliae
Killer Whale
Orcinus orca
Dall's and/or Harbour Porpoise
Phocoenoides dalli/Phocoena phocoena

Dall's and harbour porpoise clicks are indistinguishable from one another. 
To make the porpoise calls audible, the audio file is 20 times louder and 6 times slower than normal.
