The Science Behind Whale Recovery in Alaska

Watch a new video to find out how NOAA scientists recover whales in Alaska. See how they use photo identification to identify individual humpback whales and learn more about their population abundance. Also see how we study what and how much they eat. This research is made possible by the success of the Marine Mammal Protection Act, celebrating its 40th anniversary this year.
