The Amery Ice Shelf in Antarctica has just produced its biggest iceberg in more than 50 years. The piece occupies 1,636 square kilometers - smaller than the Isle of Skye in Scotland - called D28. 

The size of the iceberg means that it must be monitored and tracked as it may be harmful to transportation. Since the early 1960s, Amery has never cut a larger iceberg. The previous one was 9,000 square kilometers.

Amery is the third largest ice shelf in Antarctica and an important drainage channel in the eastern part of the continent.
