WHICH ICEBREAKER HAS A DEEP-SEA ROBOT?
The German research ship Polarstern, which was designed as an icebreaker, has been in use for 33 years— with no end in sight. Each year it spends an average of 320 days at sea exploring the polar waters and transporting people and supplies to the Arctic and Antarctic Oceans. In addition to underwater gliders the ship is also equipped with a remotely operated vehicle (deep-sea robot). Polarstern was the first conventionally powered vessel to reach the North Pole— on September 7, 1991. Since 1982 it has traveled over 1.7 million miles, equivalent to 67 trips around the Earth at the latitude of the Equator.
