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,
