Antarctica
B22H is an Antarctic iceberg tracked by the U.S. National Ice Center. As of 6 November 2026, it measures about 15 km by 11 km, roughly 75 km², and lies at 70.22° S · 163.68° E. Its area is similar to that of Paris (105 km²). It lies about 2,200 km from the South Pole.

Every iceberg is a reminder that polar ice is retreating. When you adopt it, you receive a certificate in your name and, if you wish, yearly news of your iceberg and of the sea ice.
Melting ice is one of the clearest signs of climate change, but it happens far from our eyes. Mon Iceberg makes it concrete: a real iceberg, with a name and a position, and every year news of it and of the sea ice.
The U.S. National Ice Center (USNIC) names Antarctic icebergs that are at least 10 nautical miles (about 18.5 km) along their longest axis. The letter shows the quadrant of Antarctica where the iceberg was first sighted: A between 0° and 90° west (Bellingshausen and Weddell seas), B between 90° and 180° west (Amundsen Sea and eastern Ross Sea), C between 90° and 180° east (western Ross Sea and Wilkes Land), D between 0° and 90° east (Amery Ice Shelf and eastern Weddell Sea). The number follows the order of discovery. When an iceberg breaks up, its pieces get an extra letter: B22A is a fragment of iceberg B22.
Large Antarctic icebergs are called tabular: flat, with vertical cliffs, they break off ice shelves, the vast floating extensions of the Antarctic ice sheet. This process, called calving, is natural; but a warming ocean, which melts ice shelves from below, can weaken them. As with any iceberg, about 90% of their volume lies underwater, because ice is slightly less dense than seawater.
USNIC locates them on satellite images, especially radar, which sees through the polar night and clouds. Icebergs drift with winds and currents, notably the Antarctic Circumpolar Current, and can stay off the continent for years before moving north, where they break up and melt in warmer water. Mon Iceberg updates its catalogue from these public reports.
