These sculpted icebergs, slowly melting as they float through the Southern Ocean, provide a quiet reminder that the ice covering Antarctica is not a static mass. Should the vast ice sheet now overlaying western Antarctica disappear, sea level would rise some six meters, flooding the world's coastlines. To better gauge the risk of such a disaster, European geologists have carefully studied the collapse of a similar ice sheet that blanketed the Barents Sea during the last ice age. In "The Eurasian Arctic During the Last Ice Age," Martin J. Siegert, Julian A. Dowdeswell, John-Inge Svendsen and Anders Elverhøi summarize the results of those research efforts.
