Baffin Island (native name, Qikiqtaaluk), French: Île de Baffin) in the territory of Nunavut is the largest member of the Canadian Arctic Archipelago. It is the largest island in Canada and the fifth largest island in the world, with an area of 507,451 km² (195,928 sq mi). It has a population of 11,000 (2007). It is named after British explorer William Baffin. The island was known to the Norse as Helluland.
Geography
Baffin Island lies between Greenland and the Canadian mainland. It is separated from Greenland on the north and east by Baffin Bay and Davis Strait. The Hudson Strait separates the island from the Labrador-Ungava mainland - of which Quebec and Newfoundland and Labrador are a part - on its south. On the west and north, Foxe Basin, the Gulf of Boothia and Lancaster Sound separate Baffin Island from the rest of the archipelago. With an area of 195,928 square miles (507,451 square km), it is the largest island in Canada and the fifth largest in the world. It is a part of Nunavut, the largest and newest territory of Canada, which was separated officially from the Northwest Territories on April 1, 1999. The territory's capital, Iqaluit, is located on the southeastern coast of Baffin Island. Until 1987, the town shared the name Frobisher Bay with the bay on which it is located.
The two largest lakes on the island are in the central south of the island Nettilling Lake (5066 km², 1,956 sq mi) and further south Amadjuak Lake.
Climate
Most of Baffin Island lies above the Arctic Circle and all the communities from Pangnirtung north are subject to Polar night and the midnight sun. For example, the eastern community of Clyde River experiences continuous sunlight from May 14 to July 28, a period of nearly 3 months. In addition the long period from April 26 until May 13 and from July 29 until August 16 when twilight is the darkest part of the day, means the community has less than 4 months of light. In the winter the sun sets on November 22 and does not rise again until January 19 of the following year. However, unlike places such as Alert, twilight occurs for at least 4 hours a day.
Barnes ice cap
The Barnes icecap is found in the central part of the island. It is Canada's oldest ice, being approximately 20,000 years old. It is a remnant of the Laurentide ice sheet, which covered much of Canada during the last ice age. [1] Covering close to 6,000 km2, the ice cap has thinned 1.7 m (6 ft) between 1970 and 1984. William Sneed and his colleagues at the University of Maine compared historical and current data on one of Barnes's three ice domes and found a link between the warming climate and the accelerating thinning. [1]
Baffin Mountains
The Baffin Mountains are a mountain range running along the northeastern coast of Baffin Island and Bylot Island, and are part of the Arctic Cordillera. The ice-capped mountains are some of the highest peaks of eastern North America, reaching a height of 1525-2146 meters above sea level. While some mistakenly consider them a separate range due to their island locale, they are closely related to the other mountain ranges that make the much larger Arctic Cordillera mountain range.
This rugged, mountainous ecoregion, having a high arctic ecoclimate, is characterized by low species diversity and sparse vegetative cover. The dominant vegetation is an inconsistent cover of mosses, lichens, and cold-hardy vascular plants such as sedge and cottongrass. [2]
Wildlife
Baffin Island has both year-round and summer visitor wildlife. On land, examples of year-round wildlife are barren-ground caribou, polar bear, arctic fox, arctic hare, lemming and arctic wolf.
Year-round animal life
Barren-ground caribou herds migrate in a limited range from northern and mid-Baffin island down to the southern part in winter, and migrate back north in the summer, even to the southern Frobisher Bay peninsula, next to Resolution Island.
Polar Bears can be found all along the coast, but are most prevalent where the sea ice is located as pack ice, where their major food source — ringed seals (jar seal) and bearded seals — lives. Polar bears mate approximately every year with from one to three cubs being born around March. Female polar bears may travel 10-20 km (6-12 mi) inland to find a large snow bank where they dig a den in which to spend the winter and use for birthing.
Arctic fox are found on the fast ice, remaining close to land in their search for seals. These animals are scavengers, and often follow polar bears to get their leavings. On Baffin Island, arctic foxes are sometimes trapped by Inuit, though there is not a robust fur-industry.
Arctic hare are found throughout the island. Their fur is pure white in winter and molts to a scruffy dark grey in summer. Arctic hare, along with lemmings, are a primary food source for the island's fox and wolf populations.
Lemmings are also found throughout the island, and are a major food source for the fox, wolves and the snowy owl. In the winter, lemmings dig complicated tunnel systems through the snow drifts in order to reach their food supply of dry grasses and lichens.
The arctic wolf is also a year-round resident of the island. Unlike the grey and brown wolves in the southern climates, these wolves tend to hunt alone rather than in packs, although a male-female pair may hunt together.
The ringed seal is a year-round resident of Baffin Island, where it lives off-shore within 8 km (5 mi) of land. During the winter, it makes a number of breathing holes through ice up to 8 ft thick by visiting each one often, and keeping the hole open and free from ice. In March, when a female is ready to whelp, she will enlarge one of the breathing holes that has snow over it, and create a small "igloo" where they whelp one or two pups. Within three weeks the pups are in the water and swimming. During the summer, ringed seals keep to a narrow territory approximately 3 km (2 mi) along the shoreline. If pack ice moves in, they may venture out 4-10 km (2½-6 mi) and follow the pack ice, dragging themselves up on an ice floe to take advantage of the sun.
Migratory wildlife
- Land visitors
Summer land visitors to Baffin Island all have wings and all come to the island to nest. Baffin Island is one of the major nesting destinations from the Eastern and Mid-West flyways for many species of migrating birds. Waterfowl include Canada goose, snow goose and brent goose (brant goose). Shore birds include the phalarope, various waders (commonly called sandpipers), murres including Brünnich's guillemot, and plovers. Three gull species also nest on Baffin Island: glaucous gull, herring gull and ivory gull. Long-range travellers include the arctic tern, which migrates from Antarctica every spring. The variety of water birds that nest here include coots, loons, mallards, and many other duck species.
- Water species
These include the Harp Seal, walrus, beluga whale, narwhal and bowhead whale.
Harp seals (or saddle-backed seals) are marine mammals that migrate from major birthing grounds off the coast of Labrador and from a birthing ground off the south-east coast of Greenland to Baffin Island for the summer. [3] Migrating at speeds of 15–20 km/h (9-12 mph), the pods swim in sync, surfacing for air at the same time, then diving and swimming up to 1–2 km (0.6-1.2 mi) before surfacing again. From their birthing grounds they migrate in large pods, that consist of a hundred or more seals, to within 1–8 km (0.6-5 mi) of the shoreline, which they then follow, feeding on crustaceans and fish.
The walrus, a large, semi-aquatic mammal that is the only non-seal pinniped, do not actually migrate far off land in the winter. They merely follow the "fast ice", or ice that is solidly attached to land, and stay ahead of it as the ice hardens further and further out to sea. As winter progresses, they will always remain where there is open water free of ice. When the ice melts, they move in to land and can be found basking on rocks close to shore. One of the largest walrus herds can be found in the Foxe Basin on the western side of Baffin Island.
Beluga whale (also know as "white whale"), is a marine mammal rarely found south of latitude 70°N. These whales migrate along the coast of Baffin Island as some head north to the feeding grounds in the Davis Strait between Greenland and Baffin Island, or into the Hudson Strait or any of the bays and estuaries in between. Usually travelling in pods of two or more, they can often be found very close to shore (100 m, 300 ft, or less), where they come up to breathe every 30 seconds or so as they make their way along the coastline eating crustaceans.
Narwhals, in the same family as the Beluga, are known for their one straight tusk or two twisted tusks (males only). These marine mammals can also be found along the coast of Baffin Island in the summer. Much like their beluga cousins they may be found in pairs or even in a large pod of ten or more males, females and newborns. They also can be often found close to the shoreline, gracefully pointing their tusks skyward as they come up for air. When they first arrive, the males arrive a few weeks ahead of the females and young.
The bowhead whale is the largest summer visitor to Baffin Island. Found throughout the Arctic range, one group of bowhead whales are known to migrate to the Foxe Basin, a bay on the western side of Baffin Island. It is still not known if they just visit for the lush sea bounty or calve in the Foxe Basin.
