Norwegian explorer Fridtjof Nansen deliberately froze his ship Fram into Arctic sea ice to drift with the pack. The expedition showed that drifting with the ice could be used as a planned method for Arctic research, not only as a survival situation. This idea later inspired Soviet drifting ice stations.
Soviet aircraft landed a small team and supplies on a sea-ice floe near the North Pole, establishing North Pole-1 (Severny Polyus-1). The station was designed to drift with the ice while the crew carried out regular scientific observations. It marked a major shift toward long-duration, instrumented research in the central Arctic Ocean.
A formal ceremony raised the Soviet flag and marked the station’s official opening on the drifting ice. The event helped frame the station as a national scientific program rather than a one-off expedition. It also signaled that the USSR intended to sustain research activity in the high Arctic.
After roughly nine months on the drifting floe, the four-person crew was taken off the ice by Soviet icebreakers Taimyr and Murman near Greenland. The successful extraction proved that a crewed drifting station could be deployed and recovered safely, enabling later stations to be planned as repeatable operations. North Pole-1 became the model for the Soviet “Severny Polyus” (North Pole) series.
During and immediately after the drift, the team reported results from meteorology, oceanography, and geophysics, including how the ice drift affected their work plan. These publications helped establish drifting stations as credible scientific platforms, not only symbolic feats. They also provided a template for the kinds of measurements later stations would repeat systematically.
After World War II, the USSR revived the drifting-station concept with Severny Polyus-2 (North Pole-2). It showed that the earlier North Pole-1 method could be scaled into a continuing program rather than a single historic expedition. This restart set the stage for regular, long-term monitoring of the central Arctic environment.
From the mid-1950s onward, the Soviet program increasingly maintained two or three drifting stations at the same time, creating near-continuous occupation of the Arctic pack ice. This sustained presence supported repeated measurements of weather, sea ice, and ocean conditions. It also embedded Arctic research into routine state logistics: aviation supply, icebreaker support, and planned crew changes.
In 1954 the USSR launched a major central-Arctic effort that included two drifting stations (North Pole-3 and North Pole-4) operating as part of a coordinated expedition. Running multiple stations at once expanded geographic coverage and increased the amount of continuous data collected. This approach helped turn drifting stations into a system for Arctic-wide observation.
Severny Polyus-31 (North Pole-31) finished its work in 1991, identified by the Arctic and Antarctic Research Institute as the last Soviet drifting station. Its end marked a turning point: the Soviet drifting-station system could not be maintained through the political and economic upheaval of the USSR’s final year. The program’s Soviet phase effectively concluded with this station’s closure.
Later in 1991, NP-31 was reported abandoned after breaking away from pack ice and drifting near Alaska, with fuel drums and other materials left on the floe. The incident highlights one practical consequence of the program’s abrupt ending: logistical and environmental risks increased when stations could not be recovered as planned. It also illustrates how drifting stations could cross into other countries’ areas of concern as they moved with ocean and ice circulation.
After a post-Soviet pause, Russia restarted the Severny Polyus drifting-station program by opening North Pole-32. This restart reflected renewed national interest in Arctic monitoring and operations, and it drew on the Soviet model of setting up a base on a stable ice floe and resupplying it through specialized Arctic logistics. The reopening also connected the older 1937–1991 program legacy to a new Russian phase.
