February 7, 2017 — First drones, and now satellites are allowing scientists to spy on whales — for research, that is.
Though they are massive animals, whale populations are difficult to monitor, according to researchers. Drones have been used to capture footage of whales, and now scientists are turning to even higher-flying help. Researchers in Australia are using satellite imagery to track local humpback whale populations, reported the Australian Broadcasting Corp. (ABC).
Humpback whales were considered an endangered species under the Endangered Species Act of 1973. However, the U.S. National Marine Fisheries Service lifted the whales’ endangered status last year as a result of successful conservation efforts. But despite this success, the migratory whales are difficult to track, and many population estimates are largely speculative, according to Curt Jenner, managing director of the Centre for Whale Research in Western Australia.
