<P> Icebergs are usually confined by winds and currents to move close to the coast . The largest icebergs recorded have been calved, or broken off, from the Ross Ice Shelf of Antarctica . Iceberg B - 15, photographed by satellite in 2000, measured 295 by 37 kilometres (183 by 23 mi), with a surface area of 11,000 square kilometres (4,200 sq mi). The largest iceberg on record was an Antarctic tabular iceberg of over 31,000 square kilometres (12,000 sq mi) (335 by 97 kilometres (208 by 60 mi)) sighted 150 miles (240 km) west of Scott Island, in the South Pacific Ocean, by the USS Glacier on November 12, 1956 . This iceberg was larger than Belgium . </P> <P> When a piece of iceberg ice melts, a fizzing sound called the "Bergie Seltzer" is produced . This sound is made when the water - ice interface reaches compressed air bubbles trapped in the ice . As this happens, each bubble bursts, making a' popping' sound . The bubbles contain air trapped in snow layers very early in the history of the ice, that eventually got buried to a given depth (up to several kilometers) and pressurized as it transformed into firn then to glacial ice . </P> <Ul> <Li> Iceberg B - 15 11,000 km (4,200 sq mi), 2000 </Li> <Li> Iceberg A-38, about 6,900 km (2,700 sq mi), 1998 </Li> <Li> Iceberg A-68, (Larsen C) 5,800 km (2,200 sq mi), 2017 </Li> <Li> Iceberg C - 19, 5,500 km (2,100 sq mi), 2002 </Li> <Li> Iceberg B - 9, 5,390 km (2,080 sq mi), 1987 </Li> <Li> Iceberg B - 15A, 3,100 km (1,200 sq mi), broke off 2003 </Li> <Li> Iceberg B - 31, 615 km (237 sq mi), 2014 </Li> <Li> Iceberg D - 16, 310 km (120 sq mi), 2006 </Li> <Li> Ice sheet, 260 km (100 sq mi), broken off of Petermann Glacier in northern Greenland on Aug 5, 2010, considered to be the largest Arctic iceberg since 1962 .
