The polar bear is a hypercarnivorous species of bear. Its native range lies largely within the Arctic Circle, encompassing the Arctic Ocean and its surrounding seas and landmasses, which includes the northernmost regions of North America and Eurasia. It is the largest extant bear species, as well as the largest extant land carnivore. A boar weighs around 350–700 kg (770–1,540 lb), while a sow is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.
Glaciology is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice.
Franz Josef Land, Frantz Iosef Land, Franz Joseph Land or Francis Joseph's Land is a Russian archipelago in the Arctic Ocean. It is inhabited only by military personnel. It constitutes the northernmost part of Arkhangelsk Oblast and consists of 192 islands, which cover an area of 16,134 square kilometers (6,229 sq mi), stretching 375 kilometers (233 mi) from east to west and 234 kilometers (145 mi) from north to south. The islands are categorized in three groups separated by the British Channel and the Austrian Strait. The central group is further divided into a northern and southern section by the Markham Sound. The largest island is Prince George Land, which measures 2,741 square kilometers (1,058 sq mi), followed by Wilczek Land, Graham Bell Island and Alexandra Land.
Matthew Alexander Henson was an African American explorer who accompanied Robert Peary on seven voyages to the Arctic over a period of nearly 23 years. They spent a total of 18 years on expeditions together. He is best known for his participation in the 1908–1909 expedition that claimed to have reached the geographic North Pole on April 6, 1909. Henson said he was the first of their party to reach the North Pole.
Devon Island is an island in Canada and the largest uninhabited island in the world. It is located in Baffin Bay, Qikiqtaaluk Region, Nunavut, Canada. It is one of the largest members of the Arctic Archipelago, the second-largest of the Queen Elizabeth Islands, Canada's sixth-largest island, and the 27th-largest island in the world. It has an area of 55,247 km2 (21,331 sq mi). The bedrock is Precambrian gneiss and Paleozoic siltstones and shales. The highest point is the Devon Ice Cap at 1,920 m (6,300 ft) which is part of the Arctic Cordillera. Devon Island contains several small mountain ranges, such as the Treuter Mountains, Haddington Range and the Cunningham Mountains. The notable similarity of its surface to that of Mars has attracted interest from scientists.
The Arctic wolf, also known as the white wolf or polar wolf, is a subspecies of grey wolf native to the High Arctic tundra of Canada's Queen Elizabeth Islands, from Melville Island to Ellesmere Island. Unlike some populations that move between tundra and forest regions, Arctic wolves spend their entire lives north of the northern treeline. Their distribution to south is limited to the northern fringes of the Middle Arctic tundra on the southern half of Prince of Wales and Somerset Islands. It is a medium-sized subspecies, distinguished from the northwestern wolf by its smaller size, its whiter colouration, its narrower braincase, and larger carnassials. Since 1930, there has been a progressive reduction in size in Arctic wolf skulls, which is likely the result of wolf-dog hybridization.
Axel Heiberg Island is an uninhabited island in the Qikiqtaaluk Region, Nunavut, Canada. Located in the Arctic Ocean, it is the 32nd largest island in the world and Canada's seventh largest island. According to Statistics Canada, it has an area of 43,178 km2 (16,671 sq mi). It is named after Axel Heiberg.
The Norwegian Polar Institute is Norway's central governmental institution for scientific research, mapping and environmental monitoring in the Arctic and the Antarctic. The NPI is a directorate under Norway's Ministry of Climate and Environment. The institute advises Norwegian authorities on matters concerning polar environmental management and is the official environmental management body for Norwegian activities in Antarctica.
The Philomel-class gunvesselHMS Newport was launched in Wales in 1867. Having become the first ship to pass through the Suez Canal, she was sold in 1881 and renamed Pandora II. She was purchased again in about 1890 and renamed Blencathra, taking part in expeditions to the north coast of Russia. She was bought in 1912 by Georgy Brusilov for use in his ill-fated 1912 Arctic expedition to explore the Northern Sea Route, and was named Svyataya Anna, after Saint Anne. The ship became firmly trapped in ice; only two members of the expedition, Valerian Albanov and Alexander Konrad, survived. The ship has never been found.
Franklin's lost expedition was a failed British voyage of Arctic exploration led by Captain Sir John Franklin that departed England in 1845 aboard two ships, HMS Erebus and HMS Terror, and was assigned to traverse the last unnavigated sections of the Northwest Passage in the Canadian Arctic and to record magnetic data to help determine whether a better understanding could aid navigation. The expedition met with disaster after both ships and their crews, a total of 129 officers and men, became icebound in Victoria Strait near King William Island in what is today the Canadian territory of Nunavut. After being icebound for more than a year Erebus and Terror were abandoned in April 1848, by which point Franklin and nearly two dozen others had died. The survivors, now led by Franklin's second-in-command, Francis Crozier, and Erebus's captain, James Fitzjames, set out for the Canadian mainland and disappeared, presumably having perished.
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately 14,060,000 km2 (5,430,000 sq mi) and is known as one of the coldest of oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been also been described as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean.
Robert Stein was a German-American translator, interpreter of Eskimo–Aleut languages, and amateur Arctic explorer whose contributions in the field of Arctic research were largely ineffectual.

Fred Bowerman Kniffen was an American geographer and distinguished professor in the Department of Geography and Anthropology at Louisiana State University for over 64 years. Kniffen had a background in anthropology, geography, and geology when he arrived at Louisiana State University in the late 1920s. While there, he made great strides in the Department of Geography and Anthropology that led to the development of new research areas, additional courses, and well trained graduate students. Kniffen stressed the importance of learning and understanding the history of geography, along with blending physical geography and anthropology with cultural geography. During Kniffen's time at Louisiana State University, he was an advocate for interdisciplinary research. Kniffen became a distinguished professor in the department in 1966, later becoming Boyd professor in 1967.
