Exploration to the north of the Arctic Circle in the Renaissance was both driven by the rediscovery of the Classics and the national quests for commercial expansion, and hampered by limits in maritime technology, lack of stable food supplies, and insufficient insulation for the crew against extreme cold.

=== Renaissance advancements in cartography ===

A seminal event in Arctic exploration occurred in 1409, when Ptolemy's Geographia was translated into Latin, thereby introducing the concepts of latitude and longitude into Western Europe. As a result navigators were better able to chart their positions. The Inventio Fortunata, a lost book, describes in a summary written by Jacobus Cnoyen but only found in a letter from Gerardus Mercator, voyages as far as the North Pole. One widely disputed claim is that two brothers from Venice, Niccolo and Antonio Zeno, allegedly made a map of their journeys to that region, which were published by their descendants in 1558.

=== Northwest Passage ===

The Northwest Passage connects the Atlantic and Pacific Oceans via the Arctic Ocean. Since the discovery of the American continent was the product of the search for a route to Asia, exploration around the northern edge of North America continued for the Northwest Passage. John Cabot's initial failure in 1497 to find a Northwest Passage across the Atlantic led the British to seek an alternative route to the east. Interest re-kindled in 1564 after Jacques Cartier's discovery of the mouth of the Saint Lawrence River. Martin Frobisher had formed a resolution to undertake the challenge of forging a trade route from England westward to India. From 1576 to 1578, he took three trips to what is now the Canadian Arctic in order to find the passage. Frobisher Bay is named after him. In July 1583, Sir Humphrey Gilbert, who had written a treatise on the discovery of the passage and was a backer of Frobisher's, claimed the territory of Newfoundland for the English crown. In 1585, under the employ of Elizabeth I, the English explorer John Davis entered Cumberland Sound, Baffin Island. Davis rounded Greenland before dividing his four ships into separate expeditions to search for a passage westward. Though he was unable to pass through the icy Arctic waters, he reported to his sponsors that the passage they sought is "a matter nothing doubtfull [sic]," and secured support for two additional expeditions, reaching as far as Hudson Bay. Though England's efforts were interrupted in 1587 because of the Anglo-Spanish War, Davis's favorable reports on the region and its people would inspire explorers in the coming century. In 1609, while in the service of the Dutch East India Company, the English explorer Henry Hudson sailed up what is now called the Hudson River in search of the Passage; he reached present-day Albany, New York, before giving up. He later explored further north into the Arctic and Hudson Bay for the Passage.

=== The Northeast Passage ===

The Northeast Passage is a broad term for any route lying above the Eurasian continent and stretching between the waters north of the Norwegian Sea to the Bering Strait. The "Northern Sea Route" is defined as a specific portion of such routes. The Northern Sea Route (capitalized) as currently officially defined by Russian Federation law includes shipping lanes falling within Russia's EEZ and extending from the Kara Sea to the Bering Strait along the Russian northern coast. The idea to explore this region was initially economic, and was first put forward by Russian diplomat Dmitry Gerasimov in 1525. The entire route laid in Arctic waters and parts and was usually covered in ice, making it a very perilous journey. In the mid-16th century, John Cabot's son Sebastian helped organize just such an expedition, led by Sir Hugh Willoughby and Richard Chancellor. Willoughby's crew was shipwrecked off the Kola Peninsula, where they eventually died of scurvy. Chancellor and his crew made it to the mouth of the Dvina River and the town of Arkhangelsk, where they were met by a delegation from the Tsar, Ivan the Terrible. Brought back to Moscow, he launched the Muscovy Company, promoting trade between England and Russia. This diplomatic course allowed British Ambassadors such as Sir Francis Cherry the opportunity to consolidate geographic information developed by Russian merchants into maps for British exploration of the region. Some years later, Steven Borough, the master of Chancellor's ship, made it as far as the Kara Sea, when he was forced to turn back because of icy conditions.

Western parts of the passage were simultaneously being explored by Northern European countries like England, the Netherlands, Denmark and Norway, looking for an alternative seaway to China and India. Most notable is the 1596 expedition led by Dutch navigator Willem Barentsz who discovered Spitsbergen and Bear Island. Fearing English and Dutch penetration into Siberia, Russia closed the Mangazeya seaway in 1619. Pomor activity in Northern Asia declined and the bulk of 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 Kolyma to the Pacific and doubled the Chukchi Peninsula, thus proving that there was no land connection between Asia and North America. Eighty years after Dezhnev, in 1728, another Russian explorer, Danish-born Vitus Bering on Sviatoy Gavriil made a similar voyage in reverse, starting in Kamchatka and going north to the passage that now bears his name (Bering Strait). It was Bering who gave their current names to Diomede Islands, discovered and first described by Dezhnev.

It was not until in 1878 that Finnish-Swedish explorer Adolf Erik Nordenskiöld made the first complete passage of the North East Passage from west to east, in the Vega expedition. The ship's captain on this expedition was Lieutenant Louis Palander of the Swedish Royal Navy.
