A new giant was born recently in the coastal waters of Antarctica. A series of images captured from May through the beginning of this month by ESA`s Envisat satellite shows the subsequent duel between the new iceberg and another as it breaks free of the Ross Ice Shelf and tries to move north.

Christened C-19 by the US National Ice Centre in Maryland, the new iceberg measured 200 x 32 km, and about 200 m thick.

As seen in the accompanying animation of images acquired by Envi

A U of T study suggests why giant gold and copper deposits are found at some volcanoes but not others, a finding that could point prospectors to large deposits of this and other valuable metals.

“There’s one characteristic that is common to all of these big gold and copper deposits anywhere in the world,” says Professor James Mungall of the Department of Geology. The ocean’s crust that is pushed down under a volcano can start to melt, which it doesn’t normally do. His study, which appea

The swirl of malleable rock in the earth’s mantle – located between the earth’s crust and core – may have greater effect on the earth’s surface than was once believed, a Purdue research team reports.

Using computer technology to create three-dimensional models of the earth’s mantle, Purdue’s Scott King has found evidence that some dramatic features of the earth’s surface could be the result of relatively rapid shifts in the direction in which crustal plat

Air-sea interaction tower built off Martha’s vineyard

In the deep waters two miles south of Edgartown on Martha’s Vineyard, not far from where, two centuries ago, the likes of Captain Ahab and a thousand others kept their watch for the great white and his kin, we are now searching to understand another potential beast in those parts: the ocean and the weather.

But this is no allegory. Hoping to avoid any recurrence in these sometimes turbulent waters of the horrendo

By examining volcanic rocks retrieved from deep in the ocean, scientists have found they can estimate the carbon dioxide stored beneath much of the earth’s surface – a development that could enhance understanding of how volcanoes affect climate. The research by University of Florida scientists and others will be reported this week in the journal Nature.

Scientists examined chunks of basalt, a type of volcanic rock formed when lava cools, from 12,000 feet below the Pacific along a massiv

Applications include nanotechnology, more

Defects such as cracks in a material are responsible for everything from malfunctioning microchips to earthquakes. Now MIT engineers have developed a model to predict a defect’s birthplace, its initial features and how it begins to advance through the material.
The model could be especially useful in nanotechnology. “As devices get smaller and smaller, understanding the phenomena of defect nucleation and growth becomes more and more
