Blue whales re-establishing former migration-NOAA

[wolfhnd]

Scientists have documented the first known migration of blue whales from the coast of California to areas off British Columbia and the Gulf of Alaska since the end of commercial whaling in 1965. In the scientific journal Marine Mammal Science, researchers from Cascadia Research Collective in Washington state, NOAA’s Southwest Fisheries Science Center in California, and Canada’s Department of Fisheries and Oceans identified 15 separate cases where blue whales were seen off British Columbia and the Gulf of Alaska. Four of the whales were identified as animals previously observed off the coast of California, suggesting a re-establishment of a historical migration pattern.
