Antarctica - Iceberg A68's Massive Collapsing Ice-cliffs

 

The gigantic A68 Antarctic Iceberg's Massive Collapsing Cliffs

Sculptural Watercolour® 2020 in a box frame 60 x 80 x 7 cm

 

 

By the end of January 2021, the stupendously large A-68 iceberg had broken into many smaller icebergs, designated alphabetically from A-68-A to A-68-N that passed safely past the island of South Georgia, and the relatively warm sea will melt all traces before too long.

Meanwhile, observers have spotted new cracks in Antarctica's Brunt Ice Shelf, and experts predict that there will be a large calving here sometime during the year. One berg is likely to be the size of the city of New York.

The cracks are a sign of considerable instability, but scientists do not know precisely why this is happening, although in general terms, calving is a natural process.

As summer arrives in the northern hemisphere where most of us live, in Antarctica winter will arrive and this entire part of our plant will soon be in perpetual darkness. This will make observing the progress of the cracks and the calving of icebergs much more difficult to observe.

By the time of spring in the Antarctic, it seems likely that large changes will be taking place to the Brunt Ice Shelf and elsewhere.

If we are now seeing a general breaking up of ice-shelves, then there will be an accelerated movement of glaciers from land to sea, and the previously in-balance natural circulation of forming and calving will become out of balance and contribute considerably to the rise in global sea levels.
