Since the 1970's, sea lion populations have declined more than 80% along the North Pacific coast. Scientists at the University of British Columbia and the Vancouver Aquarium are working together to help save Canada’s iconic and largest pinniped – the stellar sea lion. To help understand why their numbers are dropping, researchers work with the highly intelligent mammals at a unique floating laboratory. At The Open Water Research Station, free swimming seals and sea lions are observed in their natural habitat. At the research station, these tame, remarkable animals are providing fresh insights into the fragile ocean food chain of the North Pacific. Directed by Danny Mauro © 2013 Sport Diver TV
