Discovery and Exploration
Antarctica was imagined by the ancient Greeks, but not even seen until 1820.
The first time anyone set foot on Antarctica was in 1821.
The first year-round occupation – overwintering – was in 1898.
The South Pole was first reached in 1911.
3 factors rule in Antarctica – cold, wind and altitude. Antarctica holds the world record for each of these three things.
The temperature falls as you leave the coast as the continent slopes upwards and temperature falls as you go higher.
Lowest recoded on earth – Vostok station -89.2°C / -128.6°F
Average summer temperature at South Pole -27.5°C / -17.5°F
Average winter temperature at South Pole -60°C / -76°F
Mawson station in Antarctica is the windiest place on earth.
Average wind speed:
37 kmh / 23 mph
Maximum recorded gust:
248.4 kmh / 154 mph
Antarctica has many land forms
