Climate of the Arctic continuously, with 30 stations in the Arctic from 1950 to 1991. These stations collected data that are valuable to this day for understanding the climate of the Arctic Basin. shows the location of Arctic research facilities during the mid-1970s and the tracks of drifting stations between 1958 and 1975. Another benefit from the Cold War was the acquisition of observations from United States and Soviet naval voyages into the Arctic. In 1958 an American nuclear submarine, the "Nautilus" was the first ship to reach the North Pole. In the decades that followed submarines regularly roamed under the Arctic sea ice,
North Pole 1928, in the airship "Italia". The "Italia" crashed on its return from the Pole, with the loss of half the crew. In May 1937 the world's first North Pole ice station, North Pole-1, was established by Soviet scientists by air 20 kilometres (13 mi) from the North Pole. The expedition members: oceanographer Pyotr Shirshov, meteorologist Yevgeny Fyodorov, radio operator Ernst Krenkel, and the leader Ivan Papanin conducted scientific research at the station for the next nine months. By 19 February 1938, when the group was picked up by the ice breakers "Taimyr" and "Murman", their station had drifted 2850 km
