Antarctic Icebergs

Antarctica is nearly fully covered in ice and doubles in surface area each winter as the surrounding sea freezes. So it’s an especially spectacular place for viewing icebergs, like these photographed by Jan Erik Waider. The ice comes in many shapes — some clearly fractured and some sculpted by wind and water. The colors, too, are striking. Even in overcast conditions, the blues of the ice seem almost to glow from within. (Image credit: J. Waider; via Colossal)
