Bellwethers of change: Humpback whales in the North Pacific Ocean
FeaturingDr. Ted Cheeseman
September 26, 20247:00 pmPST
North Pacific humpback whales have been recovering from a low of about 1000 individuals at the end of commercial whaling in the 1970s. Dr. Cheeseman has used the AI-powered web platform Happywhale's whale ID dataset to model North Pacific humpback whale population changes over the past 20. He found that the 2014-2016 Pacific Marine Heatwave, a global record breaking event dubbed ’The Blob,’ caused a population crash in Hawaii’s whales but not Mexico’s.
