Floating ice

Your Shot photographer Kelly King knows that icebergs near Alaksa do something strange. The part underwater melts faster than the part sticking into the air, and as a result, the iceberg eventually flips itself over, revealing smooth, glass-like ice. Seabirds like kittiwakes perch on the ice to look for food. Kelly took this image not at night, but in the late morning.

Drifting valley

When it calved from the Ross Ice Shelf in March 2000, the iceberg known as B-15 was the largest iceberg in the world. At more than 4,000 square miles, it was the size of the island nation of Jamaica at its largest. It has been breaking into smaller fragments that float around Antarctica since 2005. Several of them come together in this image by Your Shot photographer Emily Walter, creating a blue valley in the Weddell Sea.
