Hydrophones Locate Right Whales

Date: 1/8/2011

Scientists using undersea hydrophones documented the appearance of endangered right whales in a region east of Greenland, where they historically were hunted but thought to be extinct. The mapping shows the whales using an area where ships commonly pass while in transit between the United States and Europe. In the last 50 years there have only been two confirmed sightings of right whales in the Cape Farewell Ground (about 500km east of the southern tip of Greenland). Scientists estimate that fewer than 450 North Atlantic right whales remain.
