Scientists from the British Antarctic Survey (BAS) are providing a view of Antarctica that has never been seen before--what the landscape is like without the ice. They have released a model using cartographic data, titled Bedmap2, in collaboration with

Interesting. I do wonder about one item mentioned in the article, "an area beneath the Byrd Glacier in Victoria Land that rests 2,870 meters below sea level". That's about 1.78 miles below sea level (current sea level, I presume). How much of the continent is actually below sea level?

@ Roger -

Most of Antarctica is about 2,800 meters above sea level. In some spots of Antarctica the ice is piled more then 4,000 meters high, but in most places the ice is 2,000 meters deep.

Antarctica is 5,100,000 miles in size, larger than the U.S.A and Mexico combined! The huge continent is surrounded by water and in the winter it triples its size because the sea turns to ice.

The transantarctic cross the entire continent of Antarctica. Some of its peaks rise more than 14,000 feet. The transartarctic chains ice free rocky areas are known as dry valleys. The valleys were carved by glaciers that once went through them. Dry snow that falls on the valleys are swept away by the wind and some valleys have lakes in them.

The South Pole is 90º south of the equator. Its longitude is 90º degrees south of the equator and its latitude 0º on the Prime Meridian. But every year the ice slips from the south pole. So, every year they have to move the pole that marks the South Pole.

The minerals that are found in Antarctica are copper, nickel, iron, gold, silver, titanium, oil, lead, and coal.

The prospect of an ice-free Antarctica sounds like a fantasy right now but could very well prove true in the year to come. Let's hope our efforts to slow down climate change and global warming keep the contents of this article in the realm of fantasy.

The article says this is happening 60% faster than government projections. Frightening.

Noted w/thanks, Cher. Reading this was really an eye-opener for me. I've been reading about the ice melting in Antarctica, the Arctic and other places where glaciers are melting and continue to be baffled that anyone could argue against the facts of climate change. THIS is what Dumbya and his henchmen should have been warning us about and "taking up (scientific) arms against" rather than Iraq. And, thanks for the additional info, Kit.
I'm just shaking my head and thinking...."if, only!"

What a terrible visual, considering the vastness of the area .

Why are we shocked? Our lifestyles are a contributing factor in climate change...

Global warming is horrifying! I just have visions of corporation chomping at the bit to go there and start mining, drilling, and fracking. Egad! Perhaps if this news reaches the mainstream media, the public will be motivated to demand action. One can only hope.

Fascinating to read and certainly the effects of global warming brings many risks and detriments to the natural environment world wide.
