Iceberg antártico del tamaño de Londres

By Phil Bainbridge

January 25, 2023 - Un iceberg enorme, cai del tamaño del Gran Londres, se ha separado de la Plataforma de Hielo de Brunt, de 150m de grosor, en la Antártida luego de que una grieta se extendió a través de toda la capa de hielo.

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.
