World's largest iceberg forms off coast of Antarctica

The iceberg has a surface area of approximately 1,668 square miles.

The iceberg, dubbed A-76, is approximately 1,668 square miles in size, making it slightly larger than the Spanish island of Majorca. Another berg afloat in the Weddell Sea, dubbed A-23A, was previously the world's largest with a surface area of around 1,498 square miles, according to the European Space Agency.

The names of icebergs are derived from the Antarctic quadrant in which they were originally sighted, followed by a sequential number, then -- if a new iceberg breaks from an already named one -- a sequential letter, according to the U.S. National Ice Center.

Earlier this year, a 490-square mile iceberg split from Antarctica's Brunt Ice Shelf into the Weddell Sea. The berg was also larger than New York City, which has a land area of about 302 square miles.
