The iceberg broke off the western side of the Ronne Ice Shelf, which is the second-largest ice shelf in Antarctica continent.
It was first spotted on May 13 by Keith Makinson, a polar oceanographer and drilling engineer for the British Antarctic Survey and was later confirmed by Christopher Readinger, an ice analyst at the U.S. National Ice Center, who used satellite imagery from the European Space Agency's Copernicus Sentinel-1 mission.
The iceberg, called A-76, is approximately 1,668 square miles in size, making it slightly larger than the Spanish island of Majorca. Another berg inundated in the Weddell Sea, called A-23A, was previously the world's largest with a surface area of around 1,498 square miles.
Once the icebergs melts, it will not lead to a sea level rise, because it was part of a floating ice shelf, just like a melting ice cube doesn't increase the level of the drink in the glass.
Icebergs raise global sea levels when they break off into the ocean and melt. If Antarctica's entire ice sheet were to melt, it could raise sea level nearly by 190 feet.
Trivia: - Why the icebergs named as A-76 or A-23A?
Icebergs are traditionally named from the Antarctic quadrant in which they were originally sighted, then a chronological number was added to it, then if the iceberg breaks, again a chronological letter will be given to it.
