The 67 pages that link to Sea ice, each with the reason it gives.

• PermafrostCompared with: Sea ice freezes water, whereas permafrost is defined by the temperature of ground.

• GlacierCompared with: Sea ice originates from ocean water rather than accumulated snowfall on land.

• AlbedoRelated: Its bright surface reflects sunlight, while melt ponds and open water lower the effective albedo.

• Polar bearRelated: Polar bears travel and hunt on sea ice, where seals surface to breathe.

• Antarctic PeninsulaRelated: Changes in sea ice around the peninsula affect ecosystems and regional climate.

• Arctic sea iceNarrower topic: Arctic sea ice is the northern regional expression of this global phenomenon.

• Ice–albedo feedbackRelated: Its bright cover reflects sunlight; retreat exposes darker ocean that absorbs more energy.

• KrillRelated: Antarctic sea ice provides habitat and food, especially for juvenile krill.

• Bering SeaRelated: Its seasonal coverage transforms the sea’s habitat and heat exchange.

• Little Ice AgeRelated: Expanded Arctic sea ice could amplify regional cooling by reflecting sunlight and altering heat exchange.

• ArcticRelated: Its seasonal cycle reshapes Arctic habitats, travel routes, and ocean-atmosphere exchange.

• Arctic foxRelated: Sea ice lets foxes travel between land and marine feeding areas.

• Ice sheetCompared with: Sea ice floats and forms from seawater, unlike land-based glacial ice sheets.

• Ice shelfCompared with: Unlike an ice shelf, it forms directly from seawater rather than flowing from land.

• Arctic explorationRelated: Its seasonal growth and drift governed ship routes, camps, and expedition survival.

• East Siberian SeaRelated: Seasonal ice cover governs access, heat exchange, and light in the sea.

• IceBroader topic: Its formation and seasonal extent influence ocean and atmospheric conditions.

• SnowpackCompared with: Sea ice is oceanic frozen water, whereas snowpack is accumulated atmospheric snow on land.

• GlaciologyBroader topic: Sea ice is natural ice studied for its formation, movement, and ocean interactions.

• Sea of OkhotskRelated: Seasonal ice covers much of the sea and strongly affects its heat and ecosystem.

• Emperor penguinRelated: Stable sea ice provides emperor penguins with breeding and chick-rearing habitat.

• Adélie penguinRelated: Its extent can alter access to feeding areas and the distance penguins travel to forage.

• Ice sheet dynamicsCompared with: Unlike land-based ice sheets, sea ice changes ocean cover without directly adding its meltwater to sea level.

• Labrador SeaRelated: Seasonal ice near Labrador and Greenland modifies air–sea heat exchange and regional habitats.

• Sea of AzovRelated: Shallow water allows parts of the Sea of Azov to freeze in winter.

• HaloclineRelated: Sea-ice formation and melt alter surface salinity, helping shape polar haloclines.

• Polar explorationRelated: Its changing extent and movement determine whether ships can reach polar coasts.

• Wildlife habitatBroader topic: For polar wildlife, sea ice is both habitat and a changing resource.

• North PoleRelated: The North Pole sits on sea ice that drifts with winds and currents.

• White SeaNarrower topic: Seasonal ice cover governs navigation and surface conditions across the White Sea.

• Arctic food webRelated: Its underside supports algae and offers habitat used by prey and predators.

• Bear (animal)Related: Loss of Arctic sea ice reduces polar bears’ access to seal-hunting habitat.

• Fabian Gottlieb von BellingshausenRelated: Pack ice constrained the ships’ routes and their access to Antarctic waters.

• IcebergCompared with: Unlike an iceberg, sea ice forms from seawater rather than calving from a glacier or ice shelf.

• Russian ArcticRelated: Its seasonal extent controls access to much of Russia’s Arctic maritime zone.

• Arctic biodiversityRelated: It provides habitat and hunting platforms while influencing marine productivity.

• Arctic Ocean circulationRelated: Its wind-driven motion and seasonal formation or melt affect surface currents and freshwater distribution.

• Labrador CurrentRelated: The current transports Arctic sea ice southward along Labrador and Newfoundland.

• Polar ecosystemRelated: Its seasonal growth and melt reshape habitats and food webs in polar seas.

• Bellingshausen SeaRelated: Its seasonal extent shapes habitat, shipping conditions, and ocean exchange.

• Common eiderRelated: Sea ice shapes the winter habitat and feeding access of northern eiders.

• Gulf of St. LawrenceRelated: Winter ice covers much of the gulf and shapes its seasonal circulation.

• Hudson Bay drainage basinRelated: The basin’s freshwater inputs meet a bay whose seasonal ice strongly shapes coastal conditions.

• Hudson StraitNarrower topic: Seasonal ice cover strongly affects travel and shipping through Hudson Strait.

• Wrangel IslandRelated: Changing sea ice connects the island’s marine food webs and affects access to coastal habitat.

• Davis StraitRelated: Seasonal ice in the strait affects access and vessel movement.

• Gulf of BothniaRelated: Seasonal ice covers much of the Gulf, with the northern bay often freezing first.

• Leopard sealRelated: Leopard seals use Antarctic sea ice for resting, breeding, and hunting near penguin colonies.

• Lyakhovsky IslandsRelated: Seasonal sea ice affects wave exposure and coastal erosion.

• De Long IslandsRelated: Seasonal ice controls access to the isolated islands.
