Three months after NASA dropped 90 rubber ducks into holes in Greenland’s fastest-moving glacier to track the melting of Arctic ice, there’s no sign of the toys.
The duckies were deposited into moulins (tubular holes) in the Jakobshavn Glacier in mid-September by Alberto Behar, a robotics expert at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. The idea was that the ducks would float along the same channels that melt waters do, and wherever they emerged would reveal the path of the disappearing ice.
The ducks have Behar’s e-mail address stamped on them, along with the word "reward" in three languages, including Inuit. NASA is offering $100 to the first person who locates a duck, London's Guardian newspaper notes.
