The Northeast Passage (abbreviated as NEP; Russian: Северо-Восточный проход, romanized: Severo-Vostochnyy prokhod, Norwegian: Nordøstpassasjen) is the shipping route between the Atlantic and Pacific Oceans, along the Arctic coasts of Norway and Russia. The western route through the islands of Canada is accordingly called the Northwest Passage (NWP). The NEP traverses (from west to east) the Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, and Chukchi Sea, and it includes the Northern Sea Route (NSR). The Northern Sea Route is a portion of the NEP. It is defined in Russian law and does not include the Barents Sea and therefore does not reach the Atlantic Ocean. However, since the NSR has a significant overlap over the majority of the NEP, the NSR term is often used to refer to the entirety of the Northeast Passage. This practice injects confusion in understanding the specifics of both navigational procedures and jurisdiction. The Northeast Passage is one of several Arctic maritime routes, the others being the Northwest Passage (going through the Canadian Arctic Archipelago and the coast of Alaska) and the Transpolar Route (going across the North Pole). The first confirmed complete passage, from west to east, was made by the Finland-Swedish explorer Adolf Erik Nordenskiöld, with the Swedish ship Vega 1878–79 backed by the royal funding of king Oscar II of Sweden. Nordenskiöld was forced to winter just a few days' sailing distance from the Bering Strait, due to pack ice.
History
11th to 17th centuries
The motivation to navigate the Northeast passage was initially economic. In Russia, the idea of a possible seaway connecting the Atlantic and the Pacific Oceans was first proposed by the diplomat Gerasimov in 1525. However, Russian settlers and traders on the coast of the White Sea, the Pomors, had been exploring parts of the route as early as the 11th century. Grigory Istoma wrote about his 1496 voyage along the passage, which was later published by Sigismund von Herberstein and influenced the planning of future expeditions. During a sail across the Barents Sea in search of the Northeast Passage in 1553, English explorer Hugh Willoughby thought he saw islands to the north, and islands called Willoughby's Land were shown on maps published by Plancius and Mercator in the 1590s, and they continued to appear on maps by Jan Janssonius and Willem Blaeu into the 1640s. By the 17th century, traders had established a continuous sea route from Arkhangelsk to the Yamal Peninsula, where they portaged to the Gulf of Ob. This route, known as the Mangazeya seaway, after its eastern terminus, the trade depot of Mangazeya, was an early precursor to the Northern Sea Route. East of the Yamal, the route north of the Taimyr Peninsula proved impossible or impractical. East of the Taimyr, from the 1630s, Russians began to sail the Arctic coast from the mouth of the Lena River to a point beyond the mouth of the Kolyma River. Both Vitus Bering (in 1728) and James Cook (in 1778) entered the Bering Strait from the south and sailed some distance northwest, but from 1648 (Semyon Dezhnev) to 1879 (Adolf Erik Nordenskiöld) no one is recorded as having sailed eastward between the Kolyma and Bering Strait.
The western parts of the passage were explored by northern European countries such as England, the Netherlands, Denmark, and Norway, looking for an alternative seaway to China and India; had it proved practicable, such a seaway would have had enormous economic and military importance. Although these expeditions failed, new coasts and islands were discovered. The most notable was the 1596 expedition led by Dutch navigator Willem Barentsz, who discovered Spitsbergen and Bear Island, and rounded the north end of Novaya Zemlya. Fearing English and Dutch penetration into Siberia, Russia closed the Mangazeya seaway in 1619. Pomor activity in Northern Asia declined and most Arctic exploration in the 17th century was carried out by Siberian Cossacks, sailing from one river mouth to another in their Arctic-worthy kochs. In 1648, the most famous of these expeditions, led by Fedot Alekseev and Semyon Dezhnev, sailed east from the mouth of the Kolyma River to the Pacific Ocean, and rounded the Chukchi Peninsula, thus proving that no land connection existed between Asia and North America.
