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".
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 February 2024, its area is about 3,900 square kilometres (1,500 sq mi), which makes it the current largest iceberg in the world. [2] [3]
The iceberg, named A23a, is about 400 meters (1,312 feet) thick, and almost 4,000 square kilometers (1,544 square miles) in area. Greater London, by way of comparison, is 1,572 square kilometers ...
The world's largest iceberg is on the move for the first time in more than three decades, scientists said on Friday. At almost 4,000 square km (1,500 square miles), the Antarctic iceberg called ...
It lost 85 square kilometres (33 sq mi) of floating ice in 2000–2001, followed by a 28-square-kilometre (11 sq mi) iceberg breaking off in 2008, and then a 260 square kilometres (100 sq mi) iceberg calving from ice shelf in August 2010. This became the largest Arctic iceberg since 1962, and amounted to a quarter of the shelf's size. [74]
The world’s biggest iceberg – more than twice the size of London - is on the move after decades of being grounded on the seafloor in Antarctica.
Alternatively, you can total all icebergs for all the days over the entire year and find the average iceberg size, and all the comets and find the average comet size, and then compare the average iceberg to the average comet in that sense (even if that might not be representative of they type of iceberg and comet that pass by each other on the ...
