Antarctic's hidden world revealed

[dipsydoodle]

Scientists have produced the most detailed map yet of the White Continent's underbelly - its rock bed.

Called simply BEDMAP, this startling view of the landscape beneath the ice incorporates decades of survey data acquired by planes, satellites, ships and even people on dog-drawn sleds.

It is remarkable to think that less than 1% of this rock base projects above the continent's frozen veil.

In the map at the top of this page, the highest elevations are marked in red/black. The light blue colour shows the extent of the continental shelf.

4. Over at 4 o'clock there's a massive impact relic

That circular structure on the coast of Wilkes Land (nearly a full circle of yellow) is classed as a "probable impact crater" about 300 miles across, made by an object estimated at 35 miles across. By comparison the Chicxulub impactor that hit the Yucatan is estimated at only 6 miles across.

2. As soon as Global Warming melts off all that Snow & Ice,

...we'll be able to see Atlantis!


Joking aside,
spectacular graphic.
