Watch a 20-Mile Long Iceberg Drift Into the Southern Ocean

Ever since a massive crack was discovered in Antarctica's Pine Island Glacier in 2011, NASA researchers and other scientists have kept a close watch on this area. The crack cleaved off an iceberg, now known as "Ice Island B31," which broke off from the glacier in November 2013, and has since been drifting across Pine Island Bay, a basin of the Amundsen Sea, toward the Southern Ocean.

According to the NASA's Earth Observatory, the ice island "will likely be swept up soon in the swift currents of the Southern Ocean..."

During the five-month-long Antarctic spring and summer, an instrument called the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra and Aqua satellites captured a series of images showing the movement if the ice island. NASA recently released a time-lapse video of these images, showing the journey of this massive chunk of ice: Read more...
