Antarktischer Eisberg, so groß wie London
January 25, 2023 -
Ein riesigeer Eisberg, fast so groß wie Greater London, ist vom 150m dicken Brunt Schelfeis in der Antarktis abgebrochen, nachdem die Sprünge sich über das ganze Schelfeis erstreckten.
The crack known as Chasm-1 had until 2012 been dormant for about 35 years but over the last decade developed naturally as the ice shelf flowed towards the sea at a rate of about 2km per year.
It is not believed to be due to climate change, as atmospheric temperatures above the Brunt Ice Shelf are consistently sub-zero, and no warmer ocean water penetrates into the cavity under the shelf. The iceberg calved when Chasm-1 extended completely through the 150-metre thick ice shelf.
