I examine how large-scale atmospheric circulation over the Southern Ocean, including the coupling of low- and high-pressure systems, helps to drive warm and moist air masses onto the West Antarctic ...

A research plane flies over the Greenland ice sheet. A team of NASA scientists deploys advanced radar technology to map the ice dimensionally. Images of an abandoned military station emerge ...

The maps here show the world as it is now ... East Antarctica: The East Antarctica ice sheet is so large—it contains four-fifths of all the ice on Earth—that it might seem unmeltable.

The latest discovery used radar to map the surface of an ice sheet, its internal layers and the bedrock below, similar to the way that doctors use ultrasound to see inside the human body.

New images from the North Sea show never-before-seen landforms that were carved by a single, colossal ice sheet 1 million years ago and subsequently buried beneath a thick layer of mud ...
