When I think of the Antarctic at all, I just think of it as this huge inert unpopulated continent that is permanently covered with ice. What I had not realized is that in places the ice covering is as much as two miles thick and that the continent contains about 50% of the world’s supply of fresh water. The ice sheet is also not static but dynamic, with complex flow patterns.
This video shows how they have used remote sensing to figure out what lies beneath the ice, which will be important in understanding how the planet reacts to climate change since the melting of the polar ice caps is going to be a major source of the rise in ocean levels. But understanding the Antarctic is fascinating for its own sake.
