Hapgood mistakenly believed that Antarctica had been free of ice in 17,000 BC and partially ice-free as late as 4,000 BC. [109] This erroneous date range could have put the mapping of Antarctica contemporary with many known prehistoric societies. More recent ice core data shows that Antarctica was last free of ice over ten million years ago. [110]
The manuscript is illustrated with a 'Turkocentric' world map, oriented with east (or rather, perhaps, the direction of midsummer sunrise) on top, centered on the ancient city of Balasagun in what is now Kyrgyzstan, showing the Caspian Sea to the north, and Iraq, Armenia, Yemen and Egypt to the west, China and Japan to the east, Hindustan ...
The ice dome known as Dome Argus in East Antarctica is the highest Antarctic ice feature, at 4,091 metres (13,422 ft). It is one of the world's coldest and driest places—temperatures there may reach as low as −90 °C (−130 °F), and the annual precipitation is 1–3 cm (0.39–1.18 in).
Using satellite observations and ice-penetrating radar, scientists are now getting a glimpse of Antarctica's lost world. Ancient landscape formed by rivers revealed deep under Antarctic ice Skip ...
<p>Chances are you make it through most days without sparing a thought for Antarctica. At just over 5.4 million square miles, it's a massive chunk of land that is nearly twice the size of ...
Study of the geology of Antarctica is hampered by the widespread ice cover The bedrock topography of Antarctica (with the ice cover digitally removed), critical to understanding the motion of the continental ice sheets Antarctica without its ice cover. This map does not consider that sea level would rise because of the melted ice, or that the ...
Wolfgang KaehlerIn Madhouse at the End of the Earth, I write about the Belgian Antarctic expedition of 1897-99, led by Commandant Adrien de Gerlache. What began as a scientific mission to the last ...
Antarctica without its ice cover. This map does not consider that sea level would rise because of the melted ice, nor that the landmass would rise by several hundred meters over a few tens of thousands of years after the weight of the ice was no longer depressing the landmass.
