Polar bears live across the Arctic, but their habitat is not simply snow and land: sea ice is central to how they hunt, travel, and find mates. This guide covers ten important Arctic regions and habitat settings, from Hudson Bay to Svalbard, and explains how conditions differ between them. It is for readers seeking clear background on where polar bears live and what makes those places suitable for them.
1. Arctic Sea Ice
Sea ice is the defining habitat feature for most polar bears because it gives them access to seals, especially ringed seals, their main prey across much of the range. Bears travel over the ice to search for seals at breathing holes and lairs, and they also use it to move between hunting areas and meet other bears. The ice is seasonal: it forms as the ocean freezes and retreats or breaks up as temperatures rise, with the timing and extent varying by region and year. When ice is unavailable, bears may spend time on land or swim between ice floes, but those alternatives do not provide the same dependable hunting platform.
2. Beaufort Sea
The Beaufort Sea lies north of Alaska and Canada’s Yukon and Northwest Territories, and its coastal habitat includes sea ice, barrier islands, and tundra. Polar bears in this region hunt seals from the ice and may come ashore when the ice retreats; coastal areas also provide places to rest and, in some locations, den. The sea-ice season and the distance between shore and ice affect how easily bears can reach hunting grounds, so conditions can differ considerably from one part of the Beaufort coast to another. This region is useful for understanding how polar bears depend on a shifting boundary between ocean ice and land rather than on a single fixed habitat.
3. Chukchi Sea
The Chukchi Sea sits between Alaska and Russia’s Chukotka Peninsula, with broad, relatively shallow marine areas that support seal populations. Polar bears use the sea ice as a hunting surface and range across waters on both sides of the international boundary; some also use nearby mainland coasts and islands when ice conditions change. The region’s ice can retreat far offshore in summer, while winter freezing restores a platform over much of the sea. The Chukchi is worth distinguishing from the Beaufort because its geography and seasonal ice pattern differ, even though both regions connect Alaska to the wider Arctic marine ecosystem.
4. Canadian Arctic Archipelago
Canada’s Arctic Archipelago is a maze of islands and channels north of mainland Canada, including parts of Nunavut and the Northwest Territories. Sea ice in its sheltered waterways can persist later into the year than in more southerly areas, and bears can use the channels to travel and hunt across a complex coastline. The archipelago also contains land suitable for maternity dens, where pregnant females shelter through winter and give birth; denning locations vary and are not limited to one kind of terrain. This region shows why a polar bear habitat may include both marine ice and land-based refuge, with conditions changing from island to island.
5. Hudson Bay
Hudson Bay is a large, seasonally ice-covered inland sea bordered by Ontario, Manitoba, Quebec, and Nunavut. In the western part of the bay, polar bears commonly spend the ice-free season on shore and return to the ice as it forms in autumn, when they can resume hunting seals. The timing of breakup and freeze-up shapes how long bears must wait on land, where they generally have fewer opportunities to catch their usual marine prey. Churchill, Manitoba, is a well-known place to observe bears along Hudson Bay, but its local conditions should not be treated as a picture of every polar bear habitat or population.
6. Foxe Basin
Foxe Basin is north of Hudson Bay, between Baffin Island and the Melville Peninsula in Nunavut, and it connects to surrounding Arctic waters through narrow passages. Sea ice is a major part of the local habitat, and bears use it to hunt seals and move through the basin’s coastal and island landscapes. Ice conditions can vary around the basin, so bears may use different areas at different times rather than remaining at one shoreline. Foxe Basin is an important region to know because it illustrates the range of Canadian Arctic settings: it is more northerly than Hudson Bay, yet still has a seasonal rhythm that affects access to prey.
7. Greenland’s Arctic Coasts
Polar bears occur along Greenland’s coasts, where sea ice, fjords, islands, and rugged land meet the North Atlantic and Arctic Ocean. In the north and northeast, bears use sea ice for hunting and movement, while coastal terrain can provide denning areas for pregnant females. The amount and persistence of ice differ between Greenland’s regions, so habitat conditions on one coast cannot be assumed to match those on another. Greenland is a useful example of how polar bear habitat follows the ice-bearing marine environment around a large island, rather than covering the interior ice sheet as if it were ordinary bear habitat.
8. Barents Sea and Svalbard
The Barents Sea lies between Norway’s Svalbard archipelago, mainland Norway, and Russia, and polar bears use its sea ice as well as nearby islands and coasts. Around Svalbard, bears may hunt on ice when it is available and come onto land as ice conditions change; pregnant females can use snow dens on land. The Barents region has experienced substantial changes in sea-ice conditions, making the location and duration of usable ice important parts of any habitat description. Svalbard is often discussed because it is a prominent Arctic archipelago, but its bears still depend on a much larger marine environment beyond the islands themselves.
9. Kara Sea
The Kara Sea is part of the Russian Arctic, east of Novaya Zemlya and north of Siberia, and includes waters around other Arctic islands. Its sea ice supplies the platform polar bears need to travel and hunt seals, while islands and mainland coasts can offer resting and denning terrain. Ice cover changes through the year, and the shape of the coastline creates different local conditions across this broad region. The Kara Sea helps complete the picture of polar bear range in northern Eurasia: bears are not confined to the better-known areas near Alaska, Canada, and Svalbard.
10. Laptev Sea
The Laptev Sea lies off northern Siberia, between the Taymyr Peninsula and the New Siberian Islands, with Severnaya Zemlya to the west. Sea ice is a defining habitat feature here, and bears use the frozen marine surface to reach seal-hunting areas and move among islands and the mainland coast. The seasonal cycle of freezing and melting changes how much of the sea is accessible as a continuous platform, while the remote coastline provides land habitat when bears are ashore. Including the Laptev Sea in a habitat overview matters because it represents another major part of the circumpolar Arctic, not just an extension of the North American range.
How to Choose
If you are comparing these regions for a school report, reading project, or wildlife trip, first decide what you need to understand: a particular population area, the role of sea ice, or denning and coastal habitat. For the basic ecological explanation, start with Arctic sea ice, then use a region such as Hudson Bay to see how seasonal ice loss affects the time bears spend on land. For a comparison of different Arctic settings, pair two regions with distinct geography, such as the enclosed channels of the Canadian Arctic Archipelago and the island-and-ocean environment around Svalbard. For travel or wildlife viewing, check current local guidance and conservation rules; a map of bear range does not mean sightings are assured or that it is safe to approach bears. The best choice is the place or habitat feature that answers your actual question, while remembering that conditions vary by season and year.
Frequently Asked Questions
Do polar bears live on land or on sea ice?
They use both, but sea ice is essential in much of their range because it lets them hunt seals. Bears also use land for resting and, in some places, maternity denning, especially when seasonal ice is absent.
What kind of habitat do polar bears prefer?
They need Arctic marine habitat with access to sea ice and seal prey. The exact mix of ice, open water, islands, and coastline varies across their range, so there is no single landscape that describes every polar bear habitat.
Where do polar bears make their dens?
Pregnant females dig maternity dens in snow, often on land in suitable coastal or island areas. Denning locations differ by region, and not all polar bears den every winter.
Are polar bears found at the North Pole?
Polar bears live across Arctic regions surrounding the Arctic Ocean, and they can travel over sea ice far from shore. The geographic North Pole is not a permanent settlement or a distinct habitat that bears occupy year-round.
Do polar bears live in Antarctica?
No. Polar bears are native to the Arctic in the Northern Hemisphere; Antarctica is in the Southern Hemisphere and has no native polar bears.
Final Thoughts
Polar bear habitat is best understood as a connected Arctic system of sea ice, seal-rich waters, coasts, islands, and denning areas. The balance among those features differs from Hudson Bay to the Laptev Sea, but the seasonal availability of sea ice remains a key part of life for bears across much of their range.
