More than 2,000 years ago, according to recent radar surveys, an underwater volcano scattered ash across the ice.
"The volcano's continuous output of heat may still be melting the base of the ice sheet, and could be partially responsible for the fast flow of a nearby glacier.
David Vaughan and Hugh Corr of the British Antarctic Survey, based in Cambridge, England, spotted signs of the eruption using ice-penetrating radar, which revealed a layer of volcanic rock embedded within the ice sheet."
Researchers have also tracked volcanos erupting under the ice in Iceland.
The Earth is currently undergoing massive ice sheet melting due to Global Warming. The evidence for this can be seen in satellite imagery. With the onset of warmer climates it would be logical to deduce that volcanic activity could also be a result of Global Warming. At the current rate of ice melt Scientists have determined the global ice sheets could be gone within the next 20 years. Factor in underwater volcanic activity increasing and we could be looking at a matter of years for the polar ice to completely disappear.
