The chunks broke off from the Ward Hunt Ice Shelf on the coast of Ellesmere Island in Canada's Nunavut territory.
One of the new floating islands of ice measures 1.9 square miles while the other is 5.4 square miles in size.
A rupture of the ice shelf in 2005 created an iceberg the size of New York’s Manhattan island and created such an impact on the ocean surface that it was detected by seismographs 155 miles away.
In a related development, scientists say this summer’s weather conditions will probably prevent a repeat of last year’s record melting of the Arctic ice pack.
