An iceberg in the Arctic Ocean Icebergs in Greenland as filmed by NASA in 2015. An iceberg is a piece of freshwater 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.
It is coupled to the ocean general circulation model OPA (Ocean Parallélisé) and is freely available as a part of the Nucleus for European Modeling of the Ocean. The MIT General Circulation Model is a global circulation model developed at Massachusetts Institute of Technology includes a package for sea-ice. The code is freely available there.

Numerous icebergs are formed in this period and are brought, together with ice, to the Atlantic Ocean near Newfoundland. [2] [21] The tides are semidiurnal, with an average height of 4 m (13 ft) and the maximum of 9 m (30 ft). Their speed varies between 1 and 3.7 km/h (0.62 and 2.30 mph) hour and the direction by as much as 180°.
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. Its area is about 3,900 square kilometres (1,500 sq mi), which made it one of the largest icebergs in the world until it was temporarily surpassed in size by A-76. [2] [3]
