A massive iceberg broke off Antarctica’s Pine Island Glacier in September 2017 and sea ice blocked it from drifting out to sea. It shattered over the next few months, probably because it floated in a polynya, an area of open water, in which the water was relatively warm. The Sept. 21 image shows the glacier days before it calved the iceberg. Images taken by Landsat 8. Source: USGS Land Remote Sensing Image Collections.
