Before their very eyes: Investigating the vanishing ice in the Arctic
The scientists walk across a frozen Arctic Ocean, dark specks in a sea of white. Pale clouds loom low over the bundled figures. The wind sends ice crystals skidding and swirling around them, erasing their footprints. Behind a large ice ridge, the group shelters from the subzero cold and 25mph gusts to set up their experiment. They are learning to map an area's topography by shooting lasers across the ice and snow. But even their machines seem disoriented by the whiteout conditions: the lasers bounce off whirling snowflakes before striking their targets.
