Marine Mammal Research At The Aquarium

Since 1956, researchers from the Vancouver Aquarium, an Ocean Wise ® initiative, have been conducting original studies of marine mammals on site in order to advance our knowledge necessary to enhance environmental conservation. Much of our research would be impossible to perform in the wild and there are few opportunities for researchers, in academic or government research departments, to access captive animals. We are in a unique position to study and observe aquatic life.

Below you will find a list of publications which illustrate the research done on site at the Vancouver Aquarium with marine mammals. These peer-reviewed published papers showcase research we have conducted with animals on site, as well as highlight our applied skills and expertise gained through working with these animals.
