This is a list of icebergs by total area. In 1956, an iceberg in the Antarctic was reported to be an estimated 333 kilometres (207 mi) long and 100 kilometres (62 mi) wide. Recorded before the era of satellite photography, the 1956 iceberg's estimated dimensions are less reliable.
A23a is a large tabular iceberg which calved from the Filchner–Ronne Ice Shelf in 1986. It was stuck on the sea bed for many years but then started moving in 2020. As of January 2025, its area is about 3,500 square kilometres (1,400 sq mi), which makes it the current largest iceberg in the world.
The world's biggest iceberg is on the move again after being trapped in a vortex for most of the year. A23a is 3,800 sq km (1,500 sq miles), which is more than twice the size of Greater London ...
An iceberg in the Arctic Ocean. An iceberg is a piece of fresh water ice more than 15 meters (16 yards) long [1] that has broken off a glacier or an ice shelf and is floating freely in open water. [2] [3] Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits".
Ilulissat Icefjord. The fjord contains the Jacobshavn Isbræ (Greenlandic: Sermeq Kujalleq), the most productive glacier in the Northern Hemisphere.The glacier flows at a rate of 20–35 m (66–115 ft) per day, resulting in around 20 billion tonnes of icebergs calved off and passing out of the fjord every year.
One of the world’s largest icebergs is drifting beyond Antarctic waters, after being grounded for more than three decades, according to the British Antarctic Survey. The iceberg is about three ...
In May 2021, Iceberg A-76 broke off the northwest corner of the shelf. At 4320 km 2, [4] it is larger than Majorca, several times larger than Iceberg A-74 which calved in the same year, or approximately 14% the size of Belgium. The ice of the Filchner–Ronne ice shelf can be as thick as 600 m; the water below is about 1400 m deep at the ...
At the margin between glacial ice and water, ice calving takes place as glaciers begin to fracture, and icebergs break off from the large masses of ice. [ 11 ] [ 9 ] Iceberg calving is a major contributor to sea level rise , but the ocean is not the only place that can experience ice calving. [ 11 ]
