Detailed explanation-1: -The iceberg, dubbed A-76, calved off the Ronne Ice Shelf into the Weddell Sea.
Detailed explanation-2: -A-76 split from the Ronne Ice Shelf and was first spotted by the British Antarctic Survey. The Ronne Ice Shelf is one of the biggest of several gigantic floating sheets of ice that connect to the continent’s landmass and extend out into the surrounding seas.
Detailed explanation-3: -The largest iceberg reliably assessed using satellite imagery is iceberg B15, which calved from Antarctica’s Ross Ice Shelf in March 2000 and according to NASA measured approximately 300 km long by 40 km wide (186 x 25 mi), with a surface area of 11, 000 km2 (4, 250 sq mi).
Detailed explanation-4: -Icebergs are large chunks of ice that break off from glaciers. This process is called calving. Icebergs float in the ocean, but are made of frozen freshwater, not saltwater. Most icebergs in the Northern Hemisphere break off from glaciers in Greenland, an autonomous territory of Denmark.
