Shipping lane from the Kara Sea to the Pacific Ocean

The Northeast Passage (abbreviated as NEP; Lang ru, Nordøstpassasjen) is the shipping route between the Atlantic and Pacific Oceans, along the Arctic coasts of Norway and Russia. 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.

Eighty years after Dezhnev, in 1728, another Russian explorer, Danish born Vitus Bering on Svyatoy Gavriil (Saint Gabriel) made a similar voyage in reverse, starting in Kamchatka and going north to the passage that now bears his name; the Bering Strait. It was Bering who named the Diomede Islands, which Dezhnev had vaguely mentioned. Bering's explorations of 1725–30 were part of a larger scheme of Peter the Great, known as the Great Northern Expedition. The Second Kamchatka Expedition took place in 1735–42, with two ships, Svyatoy Pyotr (Saint Peter) and Svyatoy Pavel (Saint Paul), the latter commanded by Bering's deputy in the first expedition, Captain Aleksey Chirikov. During the Second Expedition Bering became the first Westerner to sight the coast of northwestern North America, and Chirikov was the first Westerner to land there (a storm had separated the two ships earlier). On his return leg, Bering discovered the Aleutian Islands but fell ill, and Svyatoy Pyotr had to take shelter on an island off Kamchatka, where Bering died (Bering Island). Independent of Bering and Chirikov, other Russian Imperial Navy parties took part in the Second Great Northern Expedition. One of these, led by Semyon Chelyuskin, in May 1742 reached Cape Chelyuskin, the northernmost point of both the Northeast Passage and the Eurasian continent. Later expeditions to explore the Northeast Passage took place in the 1760s (Vasiliy Chichagov), 1785–95 (Joseph Billings and Gavril Sarychev), the 1820s and 1830s (Baron Ferdinand Petrovich Wrangel, Pyotr Fyodorovich Anjou, Count Fyodor Litke and others). The possibility of navigating the length of the passage was proven by the mid 19th century. However, it was only in 1878 79 that Fenno Swedish explorer Adolf Erik Nordenskiöld (born in Finland but exiled to Sweden many years before the expedition) made the first complete passage of the Northeast Passage, leading the Vega expedition from west to east. The ship's captain on this expedition was Lieutenant Louis Palander of the Swedish Royal Navy. One year before Nordenskiöld's voyage, commercial exploitation of a section of the route started with the so called Kara expeditions, exporting Siberian agricultural produce via the Kara Sea. Of 122 convoys between 1877 and 1919 only 75 succeeded, transporting as little as 55 tons of cargo. From 1911 the Kolyma River steamboats ran from Vladivostok to the Kolyma once a year. In 1912, two Russian expeditions set out; Captain Georgy Brusilov and the Brusilov Expedition in the Santa Anna, and Captain Alexander Kuchin with Vladimir Rusanov in the Gerkules (Hercules); each with a woman on board. Both expeditions were hastily arranged, and both disappeared. The German Arctic Expedition of 1912, led by Herbert Schröder Stranz, ended disastrously with only 7 of 15 crew members surviving the preliminary expedition to Nordaustlandet. In 1913 Jonas Lied organized a successful expedition through the Kara Sea to the Yenisei. Explorer and scientist Fridtjof Nansen and Siberian industrialist Stephan Vostrotin were prominent passengers. Lied had founded The Siberian company with the purpose of exporting and importing goods through the great Siberian rivers and the Kara Sea. The 1913 trip is recorded in Nansen's Through Siberia. In 1915, a Russian expedition led by Boris Vilkitskiy made the passage from east to west with the icebreakers Taymyr and Vaygach. Nordenskiöld, Nansen, Amundsen, DeLong, Makarov and others also led expeditions, mainly for scientific and cartographic purposes.

The introduction of radio, steamboats, and icebreakers made running the Northern Sea Route viable. After the Russian Revolution of 1917, the Soviet Union was isolated from the western powers, which made it imperative to use this route. Besides being the shortest seaway between the western and far eastern USSR, it was the only one that lay completely inside Soviet internal waters and did not impinge on waters of opposing countries. In 1932, a Soviet expedition on the icebreaker A. Sibiryakov led by Professor Otto Yulievich Schmidt was the first to sail all the way from Arkhangelsk to the Bering Strait in the same summer without wintering en route. After trial runs in 1933 and 1934, the Northern Sea Route was officially defined and open and commercial exploitation began in 1935. The next year, part of the Baltic Fleet made the passage to the Pacific where armed conflict with Japan was looming. A special governing body Glavsevmorput (Chief Directorate of the Northern Sea Route) was set up in 1932, with Otto Schmidt as its director. It supervised navigation and built Arctic ports. During the early part of World War II, the Soviets allowed the German auxiliary cruiser Komet to use the Northern Sea Route in the summer of 1940 to evade the British Royal Navy and break out into the Pacific Ocean. Komet was escorted by Soviet icebreakers during her journey. After the start of the Soviet German War, the Soviets transferred several destroyers from the Pacific Fleet to the Northern Fleet via the Arctic. The Soviets also used the Northern Sea Route to transfer materials from the Soviet Far East to European Russia, and the Germans launched Operation Wunderland to interdict this traffic. A convoy of seven brand new merchant vessels (900 DWT to 5500 DWT) built for the People's Republic of China but sailing under the Polish flag from Gdynia, reached the port of Pevek (via the Kara, Vilkitsky, Dmitry Laptev and Sannikov Straits), two days of navigation before the Bering Strait in 1956. In July 1965, USCGC Northwind (WAGB 282), commanded by Captain Kingdrel N. Ayers USCG, conducted an oceanographic survey between Greenland, Iceland, and Scotland and was the first western vessel to operate in the Kara Sea of the Soviet Union, for which she received the Coast Guard Unit Commendation with Operational Distinguishing Device. The real (then classified) mission of Northwind was to attempt a transit of the "Northeast Passage". The effort was not successful due to diplomatic reasons and caused an international incident between the U. S. S. R. and U. S. A.

After the Soviet Union dissolved in the early 1990s, commercial navigation in the Siberian Arctic went into decline. including the passage of the Finnish product tanker Uikku. A January 2013 Reuters News report on expanding Russian arctic natural gas shipments to Asia, stated that while shipping traffic on the NSR surged in 2012 to around 1 million tons of various kinds of cargoes, "it pales by comparison with the 1987 peak of 6.6 million tons." It also reported that the Finnish crude oil tanker Uikku was the first non Russian energy vessel to brave the NSR in 1997. Now the NSR is developing rapidly. In 2021 85 ships with around 2.75m tons of cargo made their way along the NSR, only 12 of which were under the Russian flag.

Recently, the "Main Directorate of the Northern Sea Route" ("Glavsevmorput") was established on the basis of the Naval Operations Headquarters of FSUE “Atomflot”. The main purpose of the creation of the Glavsevmorput is to organize the navigation of vessels in the waters of the Northern Sea Route. Glavsevmorput Federal State Budgetary Institution solves the following tasks: ensuring the organization of icebreaking vessels taking into account the hydrometeorological, ice, and navigation conditions in the waters of the NSR; vessels navigation in the waters of the NSR; issuance, suspension, renewal, and termination of permits for sailing vessels in the waters of the NSR. To solve these tasks, the department arranges icebreaker fleet vessels in the waters of the NSR, monitors the traffic in the NSR water area, provides information on hydrometeorological, ice, and navigation conditions, and processes information from vessels located in the NSR water area. Rosatom is a Legacy Member of the Arctic Economic Council, that’s why all the operations are aimed to establish economic well being, environmental neutrality, and human capital development.

In September 2012, Inuit Circumpolar Conference Chair Jimmy Stotts was reported as saying there is concern that increased shipping could adversely affect indigenous hunting of marine mammals. Also concerning is the lack of infrastructure on the Western Alaska coast to deal with a spill or a wrecked vessel. According to the Fourth IMO GHG Study 2020, sea cargo transportation is responsible for 2.9% of global emissions. More than that, in the next 20 years the trading maritime volume is expected to double, which may cause even worse consequences for the environment. Now marine transport produces about 1 gigaton of carbon dioxide emissions per year and has been struggling for many years to reduce its environmental impact. For example, the International Maritime Organization (IMO) has obliged sea carriers to reduce emissions by 50% by 2050. It may seem very realistic, but achieving this result may become a tough challenge. Firstly, marine transport generates 14% of all transport emissions, and, secondly, effective techniques that could replace marine engines powered by fossil fuels do not exist yet. Due to its shorter length, navigation on the NSR contributes to reducing the carbon footprint of maritime transport thus contributing to the achievement of the Paris Agreement goals.

thumb|upright=1.7|Sea ice extent in March 2013 (left) and September 2013 (right), illustrating the respective monthly averages during the winter maximum and summer minimum extents. The magenta lines indicate the median ice extents in March and September, respectively, during the period 1981–2010. Unlike the similar latitudes in Alaska and Canada (along the Northwest Passage), parts of the NEP remain ice free year round. This is mostly the case of the Barents Sea, by the northern coast of Norway and Northwestern coast of Russia. The Barents sea is affected by the currents of warm water from the Gulf Stream, feeding into the North Atlantic. The development of the icebreaking fleet is the most important condition for constant navigation in Arctic waters. Since 2008, the structure of Rosatom includes the Russian nuclear icebreaker fleet, which is the largest in the world with a container ship, four service vessels and seven nuclear powered icebreakers (“Yamal”, "50 Let Pobedy", "Taymyr", "Vaygach", "Arctic", "Siberia" and Ural). The last three are the latest universal icebreakers of the 22220 project, and the world's only transport vessel with the Sevmorput nuclear power plant in operation. In Saint Petersburg, the construction of two more universal nuclear icebreakers of project 22220 continues. They are Yakutiya (2024) and Chukotka (2026). These icebreakers will be universal, which means they will be able to change the draft from 10.5 to 8.1 meters, depending on the depth, which will allow them to work both at sea and in the mouths of Siberian rivers. They will be equipped with a power plant with two RITM 200 reactors and will be capable of overcoming ice up to 3 meters thick. At the same time, the 5th and 6th icebreakers of the 22220 project are planned to be constructed as well as 4 non nuclear icebreakers to serve shippers' investment projects. In addition, the Zvezda shipyard is working on the construction of the world's most powerful nuclear icebreaker project 10510 "Russia", scheduled to commissioning in 2027. It is also planned to build two more icebreakers of this prototype. These icebreakers will be equipped with a two reactor power plant with RITM 400 reactors with a capacity of 315 MW. The maximum ice thickness overcome by these icebreakers will exceed 4 meters.

Due to its harsh climatic conditions and the low population density, the NEP has had relatively little activity. The NSR portion of the NEP experienced its highest levels of activity during the Soviet era. The NSR greatly developed as a heavily subsidized domestic route, with traffic peaking in 1987 with 6.58 million tons of cargo carried by 331 ships over 1306 voyages. With the end of the Soviet Union and its subsidies, the NSR traffic collapsed to 1.5–2 M tons of cargo. State Corporation Rosatom assumes the possibility and functions of the NSR and ensures the safety of navigation on the high technological level. Besides organizing the navigation along the NSR and the icebreaking services with the world's only nuclear icebreaker fleet, Rosatom is planning to implement the Arctic Ice Regime Shipping System (AIRSS) methodology. This system will represent a digital space that will provide various services to cargo carriers, shipowners, captains, insurers, and other participants in the logistics market on the NSR. In particular, it involves issuing permits for the passage of vessels, monitoring, dispatching, and managing the work of the fleet. The single digital platform will collect information from all the available sources, for example, hydrometeorological data, the location of ships and icebreakers, port congestion. As a result, users will receive an advanced "ice navigator" that will allow to plot a precise route in view of the changing ice conditions of the NSR. In other words, the study of Sibul et al. proposed a path finding algorithm for the NSR strategic assessment. It uses real weather as input and find the optimal shipping route.

The term "ice free" generally refers to the absence of fast ice, i. e. continuously frozen surface ice sheet cover. Under common usage "ice free" does not mean that there is no Arctic sea ice. "Ice free" regions can contain broken ice cover of varying density, often still requiring appropriately strengthened hulls or icebreaker support for safe passage. French sailor Eric Brossier made the first passage by sailboat in only one season in the summer of 2002. He returned to Europe the following summer through the Northwest Passage. The same year Arved Fuchs and its crew sailed the Northeast Passage with the Dagmar Aaen. The Northern Sea Route was opened by receding ice in 2005 but was closed by 2007. The amount of polar ice had receded to 2005 levels in August 2008. In late August 2008, it was reported that images from the NASA Aqua satellite had revealed that the last ice blockage of the Northern Sea Route in the Laptev Sea had melted. This would have been the first time since satellite records began that both the Northwest Passage and Northern Sea Route had been open simultaneously. However, other scientists suggested that the satellite images may have been misread and that the sea route was not yet passable. In 2009, the Bremen based Beluga Group claimed they were the first Western company to attempt to cross the Northern Sea Route for shipping without assistance from icebreakers, cutting 4000 nautical miles off the journey between Ulsan, Korea and Rotterdam. The voyage was widely covered and sometimes incorrectly said to be the first time that non Russian ships made the transit. In 1997, a Finnish oil tanker, Uikku, sailed the length of the Northern Sea Route from Murmansk to the Bering Strait, becoming the first Western ship to complete the voyage. as part of a small convoy escorted by the Russian nuclear icebreaker NS 50 Let Pobedy, westward through the Bering, Sannikov, and Vilkitskiy Straits. The two vessels embarked Russian ice pilots for the voyage to the western Siberian port of Novyy, in the Yamburg region in the delta of the Ob River. The ships arrived at Novyy on 7 September, discharged their cargo to barges and departed on 12 September, bound for the Kara Gates and Rotterdam. They were the first non Russian commercial vessels to complete this journey, but not without Russian assistance. The captain of the Beluga Foresight, Valeriy Durov, described the achievement as " great news for our industry." It is not clear that this plan was followed up on. In 2009, the first two international commercial cargo vessels traveled north of Russia between Europe and Asia. In 2011, 18 ships made the now mostly ice free transit. During 2011, 34 ships made the transit up from a total of 6 ships in 2010. In 2012, 46 commercial ships made the transit. Petroleum products constituted the largest cargo group. In 2013 71 commercial ships made the transit. On 28 July 2009, the sailing yacht RX II (36 foot length), with expedition leader Trond Aasvoll and crew Hans Fredrik Haukland and Finn Andreassen left Vardø in Norway on a quest to circumnavigate the North Pole. The northern sea route proved ice free and the three Norwegians sailed into the Bering Strait on 24 September. But Russian bureaucracy managed to do what the arctic waters didn't – to stop their effort to sail around in one season. The boat over wintered in Nome, and finished the trip through the Northwest passage the following summer. Also in 2009, Ola Skinnarmo and his crew sailed the Northeast Passage aboard Explorer of Sweden, becoming the second Swedish sailboat to transit the Northeast Passage, after Adolf Erik Nordenskiöld. In September 2010, two yachts circumnavigated the Arctic: Børge Ousland's team aboard The Northern Passage, and Sergei Murzayev's team in the Peter I. These were the first recorded instances of the circumnavigation of the Arctic by sailing yachts in one season. The largest ship as of 2011 is the 117,000 tonne SCF Baltica loaded with natural gas condensate. In 2012, the LNG carrier Ob River became the first ship of its kind to transit the Northern Sea Route. The vessel completed the westbound voyage in ballast in only six days and planned to sail back to Asia in November with a full load of liquified natural gas. The growth in traffic has been startling. 46 ships sailed the entire length from Europe to East Asia during 2012. By July 2013, the administrators of the Northern Sea Route had granted permission to 204 ships to sail during the season. By that time, Arctic sea ice had declined substantial especially on the Atlantic side of the Arctic. "On July 15 extent came within 540,000 square kilometers (208,000 square miles) of that seen in 2012 on the same date (Compared to the 1981 to 2010 average, ice extent on July 15, 2013 was 1.06 million square kilometers (409,000 square miles) below average.)" (Summer 2012 Arctic sea ice volume reached a record low.) During early September 2013 the Russian battlecruiser Petr Velikiy led a flotilla of Russian navy ships with icebreaker support along the Northern Sea Route to the New Siberian Islands. About 400 ships were expected to transit the Russian portion of the route during the 2013 season, up from about 40 during 2012. On 15 September 2015, the Chinese trimaran Qingdao China set a speed record by sailing from Murmansk to the Bering Strait in 13 days. On 3 October 2019 Nanni Acquarone became the first Italian skipper with the Italian cutter Best Explorer to sail both Northwest Passage in 2012 and Northeast Passage with a sailboat clockwise. Best Explorer started 1 June 2012 from Tromsø (Norway) sailing the Northwest Passage (first Italian boat and Italian skipper) and after several years of sailing in the Pacific got the permission to follow the Northeast Passage without assistance and without a Russian on board with a crew of 5, including Salvatore Magri who sailed the Northwest Passage with Nanni. In 2019 Best Explorer left Petropavlovsk Kamchatski on 3 August and crossed the Bering Strait on 19 August reaching Murmansk on 22 September.

In 2007, Finland issued a €10 Adolf Erik Nordenskiöld and Northeast Passage commemorative coin to celebrate the 175th anniversary of Nordenskiöld's birth and his discovery of the northern sea route. The obverse features an abstract portrait of Nordenskiöld at the helm of his ship. The reverse is dominated by a pattern resembling the labyrinth formed by adjacent ice floes. The coin is one of the Europa Coins 2007 series, which celebrates European achievements in history.
