A massive island of ice that came loose from a large iceberg earlier this year is now almost through the Nares Strait, heading towards the northern Atlantic Ocean. Since it poses a significant risk to navigation, experts are keeping an eye on it.
The island calved off the Petermann Glacier, in northwestern Greenland, in mid-July, and has been making its way through the Nares Strait ever since. Scientists have dubbed it PII-2012. On August 31, the ice mass was still intact.
By September 4, however, the entire frozen island began to tear itself apart, a process that is very dangerous for ship traffic in the area. At this point, the debris is located between Greenland and Ellesmere Island.
