Up to that time, the desire to reach the pole had been coupled with that of mapping unexplored territory and collecting scientific data; after the Fram expedition there was no longer any doubt that the central part of the polar basin was an ice-covered sea and that any land still to be discovered would be peripheral. The race for the pole then degenerated into an international sporting event. Several expeditions, following in Jackson’s footsteps, tried to reach the pole from Franz Josef Land. Three were American: Walter Wellman in 1898–99, the Baldwin-Ziegler expedition in 1901–02, and the Fiala-Ziegler expedition in 1903–06. An Italian expedition led by the duke d’Abruzzi set a new record in 1900, when Capt. Umberto Cagni reached 86°34′ N.

American Robert E. Peary started working toward his polar expeditions in 1891–92 and 1893–95, when he made two long journeys across northwestern Greenland, discovering the largely ice-free Peary Land. In 1898–1902 he laid a large supply cache in Lady Franklin Bay from bases in Smith Sound, sledged around the north coast of Greenland, and reached 84°17′ N from Cape Hecla, Ellesmere Island. In 1905, aided by the expert ice navigation of Capt. Bob Bartlett, he sailed in the Roosevelt to Cape Sheridan, near the Alert’s old winter quarters, and from Cape Hecla set a new record of 87°06′ N. He also sledged around the north coast of Ellesmere Island, mapping the coast from where Nares had left off. In 1908–09 he returned, and from Cape Columbia in 1909 he set off for the pole and returned claiming to have reached it.

Just before Peary’s return to the United States in September 1909, Frederick A. Cook, an American who had been with Peary in Greenland in 1891–92 and who had spent 1907–09 in the Arctic, announced that he had reached the pole the year before with two Inuit, from the north point of Axel Heiberg Island. The matter aroused considerable controversy, which has continued to the present day. Serious doubts have been raised as to whether either man reached the pole, since neither was able to produce conclusive evidence to support his claim. In addition, many have questioned whether Peary’s navigation techniques were adequate to allow him to have known if he had reached it, although he probably came within a few miles of it; Cook’s Inuit companions later stated that they had never been out of sight of land—i.e., Ellesmere Island or Axel Heiberg Island.

In part inspired by the weakness of Peary’s and Cook’s rival claims, the Russian naval officer Georgy I. Sedov mounted an expedition aiming for the pole in 1912 aboard Svyatoy Foka. The expedition, blocked by ice in the Barents Sea, wintered on the northwest coast of Novaya Zemlya and reached Franz Josef Land only in 1913. Sedov made a forlorn attempt at sledging to the pole from a base at Tikhaya Bay in the southern part of Franz Josef Land in 1914, but he died before even reaching the northern tip of the archipelago.

The first surface expedition confirmed as having reached the pole was an American effort under Ralph Plaisted, which reached it from northern Ellesmere Island by snowmobile in 1968 (the team was airlifted off the ice cap). The following year the British Transarctic Expedition, led by Wally Herbert, was the first to reach the pole by dog team while en route from Point Barrow, Alaska, across the pole to Svalbard. The first ships to visit the pole were the U.S. nuclear submarines Nautilus (1958), which remained submerged, and Skate (1959), which surfaced through the ice. The first surface vessel to reach the pole was the Soviet nuclear icebreaker Arktika, which in 1977 approached from the direction of the New Siberian Islands. The first landing made by an aircraft at (or near) the pole was by the Soviet pilot Mikhail Vasilevich Vodopyanov when he deposited Ivan Dmitrievich Papanin’s party at the start of the drift of the first Soviet drifting station, North Pole I, in 1937.

The first attempt to fly to the pole was made in 1897, when the Swedish scientist Salomon August Andrée and two companions left Spitsbergen in a balloon. They did not return, and their fate did not become known until 1930, when their bodies and diaries were found on Kvit Island. In 1909 Walter Wellman made an unsuccessful attempt by dirigible, and in 1925 Roald Amundsen, with two Dornier-Wal flying boats, reached 87°44′ N. In May 1926 American Richard E. Byrd and pilot Floyd Bennett flew north from Spitsbergen and claimed to have reached the pole before turning back; their claim was cast into doubt after Byrd’s diary was discovered in the mid-1990s. Three days later, on May 12, Amundsen, with Lincoln Ellsworth and Umberto Nobile, set off from the same base in a semirigid airship and flew across the pole to Alaska, thus becoming the first to definitively reach the pole as well as the first to traverse the polar region.

Svalbard

Starting in 1827, a series of expeditions, most of them Swedish, surveyed the Svalbard archipelago and studied the islands’ geology and natural history. Among those who carried out this work were Balthazar Mathias Keilhau, Otto Torell, and Baron Nordenskiöld. Sir Martin Conway crossed the interior of Spitsbergen in 1896–97, and in 1898 Alfred Gabriel Nathorst explored the east coast and adjacent islands. Oceanographic and other work was done by the Dutch in the Willem Barents after 1878, by the prince of Monaco and William Spiers Bruce (1898–1914), and by the Russian admiral Stepan Osipovich Makarov in the icebreaker Yermak (1899). Coal mining was begun in Isfjord at the turn of the 20th century, and this led to further survey activity by Norwegian government expeditions and others. In 1924 a British expedition from the University of Oxford under George Binney was the first scientific expedition to make extensive use of an aircraft.
