How scientists are using facial-recognition AI to track humpback whales
After being hunted for decades, humpback whales returned to the Pacific Ocean in big numbers. Now, new technology is revealing that underwater heat waves are taking a toll on that recovery.
After decades of whaling decimated their numbers, humpback whales have made a remarkable comeback. The 50-foot giants, known for their elaborate songs, have become common in parts of the Pacific Ocean they disappeared from.
Now, a new study finds that climate change could be slowing that recovery. Using artificial intelligence-powered image recognition, the survey finds the humpback population in the North Pacific Ocean declined 20% from 2012 to 2021.
