34- Echo of the Sea

Episode summary

In British Columbia’s remote Broughton Archipelago, Alexandra Morton scans the waters listening for the melodious songs of killer whales and white-sided dolphins.


Alexandra MortonFor 25 years, Alexandra Morton has been eagerly studying the wide range of complex sounds used by killer whales and white-sided dolphins to communicate. In 1979, this scientist decided to settle with her family in the community of Echo Bay, a small marine paradise north of Vancouver Island and far removed from the hustle and bustle of urban life.

Each day, Morton takes her boat out over the waters of the Broughton Archipelago, listening for the unique sounds of killer whales and white-sided dolphins. The way of life in Echo Bay centres on calm and simplicity. Gilford Island is home to barely 40 inhabitants who produce their own electricity with generators and solar power.

ÉpaulardToday, Morton is leading a bold quest to keep this marine paradise intact. In recent years, she’s noted with alarm that the killer whales, unlike the dolphins, are no longer visiting the Broughton Archipelago. The researcher strongly suspects that salmon hatcheries are at the root of the problem. Surrounded by her team of university researchers, Morton has documented the presence of a bacteria called “fish louse”, which attacks juvenile wild salmon. Killer whales feed on wild salmon, as well as other species living in the archipelago, including eagles, grizzlies and wolves. This situation puts an entire marine ecosystem in peril.

Alexandra Morton’s love for the environment of Echo Bay leads us to discover a superb marine environment that continues to echo inside us well afterwards. Through her decades-long quest to understand cetacean communication and social structure, we discover fascinating creatures with a highly complex language.
