10 things you didn’t know about Antarctica

At first glance, it could be an island like any other, but the fact that it is not entirely covered in snow should catch your attention… Mount Erebus, whose tip forms Deception Island, is the southernmost active volcano on the planet. It last erupted in the late 1960s.

Because Antarctica is largely uninhabited and under international governance, the continent is not officially divided into time zones. The research stations choose which time zone to stick to: that of the country that finances them or that of the country geographically closest to their base (Chile for example).

A desert is defined as an area that receives less than 254 mm of precipitation per year. On average, Antarctica receives less than 50 mm. Parts of Antarctica have not received snow or rain for more than 2 million years! As the driest continent in the world, Antarctica is the largest desert on the planet. The Sahara had better watch out!

This was in 1977. The little boy, Emilio Marcos Palma, was born there a few months later. He is the first known human to be born on the continent. The Antarctic Treaty already guaranteed international governance of the territory, but Argentina hoped that having citizens born there would make its claims more legitimate. Between 1978 and 1983, 8 Argentine babies were born in Antarctica.

You may think temperatures are well below what you can tolerate. But cruises visit Antarctica between November and March, during summer in the southern hemisphere, and sail mainly to the northern part of the continent. In this area, on the peninsula, temperatures vary between -2 °C and 2 °C in summer. If you want to venture further south in the middle of winter, then woe betide you. The coldest temperature in the world was recorded there in 2010: -92 °C.

This civilian settlement, which is also a research station, bears the lovely name of Villa Las Estrellas (“The City of Stars”). It is located on an island 120 km from the tip of the peninsula. Populated by 150 souls in summer and 80 (hopefully warm) souls in winter, Villa Las Estrellas has a primary school, a gymnasium, a post office and a rudimentary hospital.

You might think that freshwater would freeze in such a cold climate, but Antarctica has about 300 lakes. How is this possible? They are underground and kept at a temperature above 0 °C by heat from the Earth’s core.

Because they are cold-blooded, reptiles depend on heat sources in their environment to get warm. They cannot survive in an icy region like Antarctica. So the penguins can sleep peacefully: there are no snakes to bother them.

That’s 75% of the world’s freshwater. There are rocks and soil beneath all this ice – the continent is twice as big as Australia. Some of the icebergs are huge themselves: one has been discovered that is larger than Jamaica. At 11,000 km2, it is the largest iceberg ever measured.

In Antarctica, each month offers different experiences. November is the beginning of summer: the icebergs are particularly massive, and the birds are courting and mating. In December, penguins sit on their eggs. In late December and January, the eggs hatch. In February and March, whale sightings are more common, and the chicks moult. Antarctica is not open to visitors the rest of the year: it is dark most of the time and temperatures are too low to bear.
