History and geography
Exploring the deep north
 

Is there a navigable passage through the Arctic?
Starting in the 16th century, seamen kept seeking a sea route that would allow them to reach Asia without having to go around Cape Horn. They hoped to find a North-West Passage across the top of Canada or a North-East Passage to the north of Russia. It was the search for these sea routes that motivated Arctic exploration. And this exploration took a heavy toll of human life: in 1845, the Erebus and the Terror disappeared together with the 134 men under the command of John Franklin. The first to find a way through the NE Passage was the Swede Nordenskjold aboard the Vega in 1878-1879, and the NW Passage was finally opened up by the Norwegian Amundsen in the Gjoa (1903-1906).

Discovery of the Arctic Drift Current
In July 1879 an expedition aboard the vessel “La Jeannette” passed through the Bering Strait hoping to reach the North Pole. In June 1881, the vessel was crushed by the ice. Three years later, Eskimos found the wreckage on the south-west coast of Greenland, 5,000 kilometres from where the vessel was wrecked. This was the first indication of the existence of a transpolar current.

Nansen and the “Fram”, trapped in the ice on purpose
In 1893, the Norwegian explorer Fridtjof Nansen became the first to use the Arctic Drift in an attempt to reach the North Pole. His vessel, the “Fram”, was specially designed to resist the pressure of the pack ice. Once trapped in the ice, the ship drifted for 3 years before being released by the ice to the north of Spitsbergen, but without drifting to the Pole.
In 1937, the Russian Ivan Papanin set up the first scientific station on the drifting ice pack at the North Pole.

Over the ice to the Pole
In 1908 and 1909, two Americans, Peary and Cook, each claimed to have reached the North Pole. After years of investigation, America’s National Geographic Society finally declared that it was Peary who had made it to the Pole. Cook was quickly discredited but doubts remain about the speed with which Peary and his team claimed to have made the journey from northern Canada to the Pole and back.
By the time Jean-Louis Etienne reached the North Pole solo pulling his sled, on 11 May 1986, only six expeditions had reached the pole “overland”: Ralph Plaisted (USA, scooter, 1968), Wally Herbert (UK, dog sled, 1969), Uemura Naomi (Japan, dog sled, 1978), Ranulph Fiennes (UK, snow scooter, 1979), Dimitri Shparo (USSR, skis, 1979), four Finns (skis, 1984) and Will Steiger (USA, dog sled, 1986), whom Jean-Louis Etienne was to meet en route to the pole.

To the Pole by air
The first attempt to fly to the Pole was made by the Swede Andrée and his two crewmen aboard the Ornen (Eagle), a hydrogen balloon. They took off from Spitsbergen in July 1897, but nothing more was heard of them for 33 years until their bodies were discovered by seal hunters on the island of Svalbard in 1930. Apparently they had walked to the island after crash-landing on the pack ice two days earlier. On 15 August 1909, the American press baron Wellman began his third attempt to reach the Pole by air (he had already tried in 1906 and 1907) aboard his airship America. This was a flexible (i.e. no interior structure) dirigible 57 m long, that had been assembled and filled with hydrogen in a hangar specially built at Spitsbergen exactly where Andrée had taken off from. The American had to turn back after flying for only a few hours.
On 9 May 1926 Admiral Byrd and his crewman Floyd Bennett left Spitsbergen in an aircraft. They returned earlier than expected (and with an oil leak) but claimed to have reached the North Pole. Doubts about their claim persist.
The same year, on 12 May, Amundsen became the first man to fly over the Pole in the airship Norge, accompanied as engineer by the Italian Nobile, who had designed the airship. In 1928, Nobile crash-landed on the ice pack in the airship Italia; Amundsen took off in a plane to try to rescue him and was never seen again.
