BBC News - East Antarctic ice sheet may be losing mass
The East Antarctic ice sheet has been losing mass for the last three years, according to an analysis of data from a gravity-measuring satellite mission.
The scientists involved say they are "surprised" by the finding, because the giant East Antarctic sheet, unlike the west, has been thought to be stable.
Other scientists say ice loss could not yet be pinned on climate change, and uncertainties in the data are large.
The US-based team reports its findings in the journal Nature Geoscience.
The data comes from Nasa's Gravity Recovery and Climate Experiment (Grace) mission.
It energises me as a scientist, but I'm not convinced that as yet it should energise anyone else
Professor Richard Alley
Grace has previously shown that the smaller West Antarctic and Greenland ice sheets are losing mass.
These two bodies of ice contain enough water to raise sea levels by about six to seven metres (20ft) each if they melted completely.
Melting the East Antarctic sheet would raise sea levels by much more - about 50-60m.
But scientists have generally discounted the possibility of it happening because the region is so cold.
The Grace measurements suggest there was no net ice loss between 2002 and 2006.
But since then, East Antarctica has been losing 57 billion tonnes (Gt) per year.

NEW ANALYSIS HINTS ANCIENT EXPLORERS MAPPED ANTARCTIC <The ARTICLE
FOR years a few imaginative authors have argued, based on 16th century maps, that the ice-covered continent of Antarctica was discovered and mapped by an ancient civilization, perhaps one from another planet. The latter proposition was dismissed by most geographers and historians as preposterous.
Nevertheless, a careful comparison of information appearing on the maps with what is now known of the continent has led a leading geologist and polar specialist to propose that the outlines of Antarctica may, in fact, have been known long before Columbus reached America.

The generally accepted view is that Antarctica was first sighted in 1820 by American seal-hunters as well as by British and Russian explorers.
The suggestion that it may have been discovered many centuries earlier has been made by Dr. John W. Weihaupt, vice chancellor for academic affairs at the University of Colorado at Denver. His analysis appears as the lead article in the Aug. 28 issue of Eos, the Proceedings of the American Geophysical Union.
Dr. Weihaupt, a specialist in seismic and gravity studies and planetary geology, conducted research at a number of Antarctic stations beginning with the International Geophysical Year of 1957- 58.
Interviewed by telephone recently, Dr. Weihaupt was reluctant to speculate on how the rough outline of Antarctica might have become known to early mapmakers, saying he was not a maritime historian. He suggested, however, that Bronze Age seafarers from the Mediterranean, trading along the east and west coasts of Africa, might have ventured farther south than previously believed.
A Peaking Period of Warming
From 2,600 to 9,000 years ago, he said, the world was warmer than at any time in the last million years, except for the period between the last two ice ages. Polar ice was presumably reduced, making high latitudes more tempting to explore.
Dr. Weihaupt says that, assuming the outline of Antarctica was known to early cartographers, the source of their information ''remains unanswered.'' Even crude mapping of a large continent would require a knowledge of navigation and geometry presumably beyond the ken of primitive navigators.
Speculation on prehistoric discovery of Antarctica began in 1956, when a map of the Atlantic Ocean purportedly drawn in 1513 by a Turkish admiral named Piri Re'is was shown by a Navy cartographer to Arlington H. Mallery, an engineer. Mr. Mallery was known for his thesis that Vikings reached American shores five centuries before Columbus.

Something I failed to mention here...The Maps were without the ICE, and were accurate to what we know now...HOW did they do that unless there was no ICE at the time is the point...

The Orontius Finaeus map shows such a gulf, suggesting the possibility it was free of ice at some prehistoric time. Dr. Weihaupt cites polar specialists who suspect the Ross Ice Shelf may break up into icebergs and vanish if the climate warms and he proposes this may already have happened after the last ice age.
