The world’s largest iceberg is on the move again, drifting through the Southern Ocean after months stuck spinning on the same spot, scientists from the British Antarctic Survey (BAS) have said.
Roughly 1,550 square miles across, the world's biggest and oldest iceberg, known as A23a, calved from the Antarctic shelf in 1986. Before its calving in 1986, the colossal iceberg hosted a Soviet ...
The largest iceberg in the world is headed toward an island with a massive population of penguins and seals, according to satellite tracking from NOAA. The trillion-ton slab of ice that scientists ...
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.
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.
The world’s largest iceberg is on the move again after decades of being grounded on the seafloor and more recently spinning on the spot, according to the British Antarctic Survey (BAS). The mega ...
The largest icebergs in the world are formed this way. Non-tabular icebergs have different shapes and include: [26] Dome: An iceberg with a rounded top. Pinnacle: An iceberg with one or more spires. Wedge: An iceberg with a steep edge on one side and a slope on the opposite side. Dry-dock: An iceberg that has eroded to form a slot or channel.
As the world’s largest iceberg, the colossus A23a is of great interest to scientists, who have closely monitored the frozen block since it calved from Antarctica’s Filchner-Ronne ice shelf in ...
