Famous for studying orca whales and proving the effects of sea lice from salmon farms on wild Pacific salmon numbers.
Morton came to Canada from USA in 1979 to study orca whales off the coast of British Columbia. According to her website, Raincoast Research, Morton was led by a whale to Echo Bay in the Broughton Archipelago which is near the north end of Vancouver Island on the east side.
In the 1990s Morton began studying how fish farms were affecting wildlife. In particular she has documented the loss of whales in the Broughton archipelago, the effects of escaped farmed salmon on the native wild salmon, as well as the lethal effects of sea lice and antibiotics on wild fish in the area.
Morton became a Canadian citizen in 1997
