In 2018 or 2019, a large chunk almost 14 km × 8 km (9 miles × 5 miles) broke off and was named A-68B, with the mother iceberg now being A-68A. [13] On 6 February 2020, A-68A began moving into open waters. [14] On 23 April 2020, a chunk measuring about 175 sq. km. (70 sq. mi.) broke off the iceberg and was named A-68C. [15]
As a glacier retreats, chunks of ice may break off in a process known as ice calving or glacier calving. As sediment-heavy glacial meltwater flows past the stationary ice block, the increased friction between the ice and sediment causes sediment build-up around the block of ice.
Fox Glacier, New Zealand. A serac (/ s ɛ ˈ r æ k ˌ ˈ s ɛ r æ k /) (from Swiss French sérac) is a block or column of glacial ice, often formed by intersecting crevasses on a glacier. Commonly house-sized or larger, they are dangerous to mountaineers, since they may topple with little warning. Even when stabilized by persistent cold ...

The largest iceberg in recent history, named B-15, was measured at nearly 300 by 40 kilometres (186 by 25 mi) in 2000. [6] The largest iceberg on record was an Antarctic tabular iceberg measuring 335 by 97 kilometres (208 by 60 mi) sighted 240 kilometres (150 mi) west of Scott Island , in the South Pacific Ocean, by the USS Glacier on November ...
The overall retreat from 1878 to 1998 has been 2 km (1.2 mi) with a mean annual retreat rate of approximately 17 m (56 ft) per year. This long-term average was markedly surpassed in recent years with the glacier receding 30 m (98 ft) per year during the period between 1999 and 2005.
