Stunning Drone Footage From Beneath The Ice Of Antarctica

Scientists use a range of techniques—from satellite observations to drilling holes—to measure sea ice thickness. Usually, such efforts look down at the sea floor. But, by equipping an underwater drone with upward-looking sonar, researchers were able to create the first high-resolution 3D maps of Antarctic sea ice. » 11/25/14 2:40pm 11/25/14 2:40pm

Here's Awe-Inspiring Evidence for One of the Planet's Biggest Floods

About 15,000 years ago, as the latest ice age was winding to a close, glaciers that covered Canada began to melt. Then, one day, those shrinking glaciers unleashed the waters of a lake the size of Lake Huron, which scoured the land from Montana to the Pacific coast. Here's what we know of the great Ice Age flood. » 10/14/14 1:27pm 10/14/14 1:27pm
