Volcano Madness

Scientists were surprised to find that their theories of how undersea volcanoes behave were wrong. It seems that even when the volcanoes are miles deep, they can erupt explosively and spew rock, lava and megatons of hot gases.

Even under the Arctic ice cap.

New evidence deep beneath the Arctic ice suggests that a series of underwater volcanoes have erupted in violent explosions in the past decade.

Hidden 2.5 miles (4 kilometers) beneath the Arctic surface, the volcanoes can range up to more than a mile (2 kilometers) in diameter and a few hundred yards (meters) tall. They formed along the Gakkel Ridge, a lengthy crack in the ocean crust where two rocky plates are spreading apart, pulling new melted rock to the surface.

Until now, scientists thought undersea volcanoes only dribbled lava from cracks in the seafloor. The extreme pressure from the overlying water makes it difficult for gas and magma to blast outward…..

….Robert Reeves-Sohn of the Woods Hole Oceanographic Institution in Massachusetts and his colleagues discovered jagged, glassy fragments of rock scattered around the volcanoes, suggesting that explosive eruptions occurred between 1999 and 2001.

There is the now standard disclaimer that any of this could possibly have anything to do with the melting of Arctic ice. While much is made by the true believers and the media (yes, that was redundant, wasn't it?) about the melting of Arctic ice, very little is written about the rapidly growing Antarctic ice. And it is growing very rapidly, indeed. See for yourself: North Pole, South Pole. Here's the Southern anomaly. That is not a declining trend, folks.
