For example, two of the largest three icebergs currently around Antarctica (A23A (1760 km 2) and B22A (1056 km 2)) were grounded in 2016/2017 in the shelf seabed. Such grounding can be a prolonged occurrence; for example, A23A has been grounded for more than three decades, since 1986.

This is a mass of floating ice formed by glaciers that have flowed down off the eastern side of Often, such chunks keep the place they’re, like the marginally bigger A23a, which remains to be in Antarctica’s Weddell Sea after breaking off, or calving, from the Filchner Ronne Ice Shelf. By distinction, some, like A68a, are whisked north on the fast-running Southern Antarctic Circumpolar Current Front, often breaking apart into smaller chunks that scientists name “bergy bits” or The iceberg A22A was photographed when it was about a third of the distance from South America towards Cape Town, South Africa. A22A is one of the largest icebergs to drift as far north as 50 degrees south latitude, bringing it beneath the daylight path of the International Space Station (ISS). In most of the 2000's A23A has been surrounded by somewhat dispersed ice floes in February except in 2001 when cloud streets show the surrounding sea cleared by the wind and a peninsular built up behind the iceberg.

An iceberg that had been the world’s largest is now breaking into pieces close to the island of South Georgia in the South Atlantic. Scientists had worried about the impact on the remote island’s wildlife if the berg had grounded on its continental shelf. Salinity levels and … The short duration and fast developments of the LLJs illustrate the benefit of vertical wind profiles with high temporal resolution. The dynamics of the LLJs were not studied in detail. They occurred during the passage of a synoptic front, when the ship operated in a polynya in the lee of a huge iceberg (A23A, size about 60 km × 80 2.

Iceberg A68a is big. Almost half the size of Jamaica. Three times the size of London. Larger than Rhode Island. And it is on the move. After breaking off from the Antarctic ice shelf three years ago, it is closing in on some of the world’s largest penguin colonies on South Georgia Island, a remote British territory in the South Atlantic, where it could block them from their hunting grounds

After breaking off from the Antarctic ice shelf three years ago, it is closing in on some of the world’s largest penguin colonies on South Georgia Island, a remote British territory in the South Atlantic, where it could block them from their hunting grounds For the remaining four regions, estimates amount to 421 ± 294 km2 and 4 ± 3 km3 (Antarctic Peninsula), 1148 ± 432 km2 and 12 ± 5 km3 (iceberg A23A), 901 ± 703 km2 and 10 ± 8 km3 (Filchner Ice Shelf), as well as 499 ± 277 km2 and 5 ± 2 km3 (Coats Land). 14.03.2018 13:51 Unique Insights into the Antarctic Ice Shelf System Ralf Röchert Kommunikation und Medien Alfred-Wegener-Institut, Helmholtz-Zentrum für Polar- und Meeresforschung.
