Differences Between the Arctic & Antarctica

Antarctica, or the south pole region, is a continent which is covered with an immense ice shelf. The Arctic region, however, is mainly located in the north polar ocean and includes several larger islands such as Greenland, Spitzbergen, Franz Josef Land, Severnaya Zemlya Wrangel Island, Bank Island, Victoria Island, Ellesmere Island and various others that all boarder countries like Russia, Canada, Alaska and Greenland. The north polar ocean is covered by year round ice caps that generally extend far south during the Arctic winter and are made up of around 16 million square kilometers of ice. Polar bears live solely in the Arctic areas, while penguins on the other hand, are found in the southern Antarctic regions. For that reason polar bears and penguins never cross paths.

The Arctic

Unlike Antarctica, the Arctic is not a continent which is the predominant different between the two polar regions. Under the massive ice cap of the Arctic lies the Arctic Ocean whose depths reach 15,000 feet below the surface. Often times the two polar regions are confused due to their having such similar names. The Arctic was discovered by Phoenician sailors years before the common era (CE). They named the newly discovered region after a polar star which guided them to the end of the earth. The star was called “Arktos” by the Greeks during this time which meant “land of the big bear”. Coincidentally, this title helps many people remember that polar bears are found in the Arctic rather than Antarctica. Also found in the Arctic region is the arctic fox, different species of seals and whales, puffins, fulmars, and other bird species.

Though the Arctic is obviously a very cold region, it is still much warmer than Antarctica in the South. Known as “the land of the midnight sun,” the Arctic is located in a landmass above 12 frozen feet of ice.

Antarctica

The most striking fact about the Antarctic continent is its almost complete glaciation. One of the most defining characteristics of this frozen region is the tremendous ice mountains. The average temperature in Antarctica is -55°C, and the continent covers the entire area from the South Pole to the southern polar circle.

Unlike the Arctic region, Antarctica was only discovered in the nineteenth century. As it was located opposite the already discovered Arctic region it simply earned the name Antarctica. Today, Antarctica is a continent of its own and is covered by a massive ice sheet 2.8 miles thick in some areas. In addition, Antarctica is surrounded by immense ice fields, which are an enormous network of interconnected valleys with high peaks.

Antarctica is home to various species of penguins, seals, whales, and birds. The massive ice desert measures 14 million square kilometers but is still the second smallest of the planet’s continents at about twice the size of Australia. Other than various scientists that are almost always present in the area, Antarctica is the world’s only completely uninhabited continent.

Arctic & Antarctica Similarities

1) Polar Position
Polar summer / Polar winter

2) Ice Coverage
Internal ice mass on mainland areas with glacial subsidence, formation of ocean, and pack ice in the north polar ocean of the Arctic and the Weddell and Ross seas in Antarctica.

3) Climate
Dry, cold, ozone hole.

4) Paleoclimatic Importance
Drilling cores enable reconstruction 200,000 to 800,000 years back.

5) Oceanographic Importance
Deep water production by accumulation of salt and formation of ice in the north polar ocean and the Labrador sea in the Arctic and the Weddell and Ross seas in Antarctica.

6) Environmental Issues
Atomic waste in the Arctic, problem of refuse disposal and crude oil in the Antarctic.

Arctic & Antarctica Differences

 

Arctic

Antarctica

 

Extension

As far as 60 degrees north

As far as 50 degrees south

Geology and relief

Arctic mostly ocean, plate boundary (volcanism), in Greenland old metamorphic stones.

Antarctica is a continent, a long geological evolution created a variety of stones and mountain ranges up to 3,794 meters.

Climate and Oceanography

Arctic is made of various bodies surrounded by ocean waters and is affected by the warm waters of the gulf stream.

Antarctica is a single main body with a circumpolar stream which allows little circulation of heat from other regions. This leads to extreme low temperatures and is the reason for the existing ice sheet.

Flora

Tundra, flowering plants

Almost no vegetation, mostly Lichens

Fauna

Marine mammals like polar bears, walrus, seals, and whales. Terrestrial mammals like wolves, foxes, hares, lemmings, reindeer, and oxen.

Marine mammals like penguins, whales, and seals.

Population

Indigenous population (Inuits, Indians, Siberians) and enduring settlements

Historically deserted though today there are impermanent settlements for scientists.

Political status

Arctic territory belongs to different countries

There are claims of sovereignty by different countries though this sovereignty is not universally recognized around the world.

Mineral resources, commodities

Little non-ferrous metal, regional carbon

Rich sources of ferrous and non-ferrous metal, crude oil and natural gas

Fishing

Fishing close to mainland

Nutrient richness has led to fishing an whaling

Research

Important research area and site of military presence

Important international research stations
