Easy travel through the relatively ice-free Northwest Passage

Easy travel through the relatively ice-free Northwest Passage For most of the year, the Northwest Passage is frozen and impassible. But during the summer months, the ice melts and breaks up to varying degrees.

The Northwest Passage (NWP) is the sea route between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Canadian Arctic Archipelago. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP).Easy travel through the relatively ice-free Northwest Passage

The various islands of the archipelago are separated from one another and from the Canadian mainland by a series of Arctic waterways collectively known as the Northwest Passages or Northwestern Passages.

For centuries, European explorers sought a navigable passage as a possible trade route to Asia. An ice-bound northern route was discovered in 1850 by the Irish explorer Robert McClure; it was through a more southerly opening in an area explored by the Scotsman John Rae in 1854 that Norwegian Roald Amundsen made the first complete passage in 1903–1906. Until 2009, the Arctic pack ice prevented regular marine shipping throughout most of the year. Arctic sea ice decline has rendered the waterways more navigable for ice navigation.Before the Little Ice Age (late Middle Ages to the 19th century), Norwegian Vikings sailed as far north and west as Ellesmere IslandSkraeling Island and Ruin Island for hunting expeditions and trading with the Inuit and people of the Dorset culture who already inhabited the region. Between the end of the 15th century and the 20th century, colonial powers from Europe dispatched explorers in an attempt to discover a commercial sea route north and west around North America. The Northwest Passage represented a new route to the established trading nations of Asia.
