Ronne and Ross Ice Shelf
« on: January 25, 2021, 03:25:04 AM »
Hello

I am interested in the Ronne Ice Shelf and Ross Ice Shelf in Antarctica.  Specifically, I want to know about their size and how it's changed over the years.

Here are the two ice shelves that I am referring to in the first map:

The Ross Ice Shelf is about 500,000 square kilometers in size.  Whereas the Ronne ice Shelf is about 430,000 square kilometers in size.

Have there been any estimates on how this has changed in decades (preferably century estimates)?  Does anyone know if there are research papers or any work done on this?

There is a dedicated Ross Ice Shelf thread, and a thread for "hazard analysis of the FRIS/RIS.."  Might find a few bits of interest in those.

A large iceberg: 172 km x 27.6 km has just broken off the Filchner-Ronne Ice Shelf.

Very large image: 5000x3000, click to enlarge

PS : Surface of the main piece about 4292 km2

PS2: The main part of the small piece (top left) is still 45.5 km2

Wow! I gave up on that ever breaking off a few years ago.

For those who like to follow icebergs, it has just been named, quite naturally, "A76".

It is currently the largest

I had to remove a message by Grygory which somehow crashed this thread, I am guessing due to its attachment.  This took some detective work:

Another Iceberg in a Month? Further west, another large rift
 (54 W 77 S)

I also removed two test messages by uniquorn which were somehow posted after this message.
