Contents • • • • • • • Overview [ ] 'NP' carry out the program of complex year-round research in the fields of, ice studies,,,,,,. On average, an 'NP' station is the host for 600 to 650 ocean depth measurements, 3500 to 3900 complex meteorology measurements, 1200 to 1300 temperature measurements and sea water probes for, and 600 to 650 launches.,, ice and other observations are also carried out there. Regular measurements of the ice floe coordinates provide the data on the direction and speed of its drift. The modern 'NP' drifting ice station resembles a small settlement with housing for polar explorers and special buildings for the scientific equipment. Usually an 'NP' station begins operations in April and continues for two or three years until the reaches the. Polar explorers are substituted yearly.

Since 1937 some 800 people were drifting at 'NP' stations. There are two groups of 'NP' stations: • stations, drifting on the (i.e. Relatively thin and short-lived ice):'NP-1' through 'NP-5', 'NP-7' through 'NP-17', 'NP-20', 'NP-21' • stations, drifting on ice islands ( fragments, that were split from the shore): 'NP-6', 'NP-18', 'NP-19', 'NP-22'. All 'NP' stations are organized by the Russian (former Soviet) (AARI). History [ ] An idea to use the for the exploration of nature in the high latitudes of the belongs to, who fulfilled it on between 1893 and 1896.

The first stations to use drift ice as means of scientific exploration of the Arctic originated in the in 1937, when the first such station in the world,, started operations. North Pole-1 was established on May 21, 1937 some 20 km from the by the expedition into the high latitudes., led. 'NP-1' operated for 9 months, during which the ice floe travelled 2,850 kilometres.

On February 19, 1938, Soviet and took off four polar explorers from the station, who immediately became famous in the USSR and were awarded titles:, geophysicist, and their leader. Since 1954 Soviet 'NP' stations worked continuously, with one to three such stations operating simultaneously each year. The total distance drifted between 1937 and 1973 was over 80,000 kilometres. Is particularly notable for its record drift, lasting nine years. On June 28, 1972 the ice floe with passed over the North Pole for the first time ever. During such long-term observations by 'NP' stations, a lot of important discoveries in were made, valuable conclusions on regularities and the connection between processes in the polar region of the 's and were obtained.
