Massive Berg Adrift in Antarctica

Thanks to their polar orbits, Landsat satellites collect images more frequently in Arctic and Antarctic regions.

The data they collect is especially useful in monitoring changes to ice shelves like this one in Antarctica.

A 315 billion-ton iceberg known as D28 has inched seaward since a western rift emerged in the Amery Ice Shelf in the early 2000s. In September of 2019, D28 finally broke free.

The freed iceberg has a surface area of more than 600 square miles, roughly comparable to the size of the Hawaiian island of Oahu. It's the largest iceberg to calve from the ice shelf since the 1960s.
