Crosson and Dotson Ice Shelves Discussion
« on: February 13, 2020, 07:18:19 PM »
PIIS has pulled all attention in the last weeks, but a few 100 km west another ice shelf had a major calving event.
Between Feb 1 and Feb 11 a part of the Dotson Ice Shelf lost a 25*3 km piece of ice. The days in-between were too cloudy for an evaluation in EOSDIS, so a more exact dating is not possible.

See attached image.

To me it looks like it had already calved by the 1st. It had moved considerably by then if you compare it to a week or so before. It just hadn't completely drifted away from the shelf yet.

Yes, happened between 21. and 25. according to the radar pics. I would post a GIF but EZGIF doesn't like me today.

But Kudos, Stephan, for finding it!

Stephan,
Good point!  ;)

Couldn't we rename this forum "Crosson and Dotson Ice Shelfs Discussion"?
Intended therefore to host any discussion on these two ice platforms and the glaciers feeding them, which would give us, relative to the Admunsen Sea Embayment, 
"PIG has calved" dedicated to the PIIS and its tributaries, which I'll see renamed "PIG Discussion".
"Thwaites Glacier Discussion"
"Crosson and Dotson Ice Shelfs Discussion"
"Getz Ice Shelf - Iceberg B-47", which I'll see renamed to "Getz Ice Shelf Discussion".
And all that will be left to do is to create the last "Abbot and Cosgrove Ice Shelfs Discussion" when the opportunity arises.

How to change 'Subject' to "Crosson and Dotson Ice Shelfs Discussion"
« Reply #5 on: February 14, 2020, 12:47:19 AM »
Change the "Subject" in the first post.  If the 'statue of limitations' prevents this, contact Neven.  He's Superman - he can do things no ordinary person can do (on this forum). ;)

(Anybody can change the subject in their own posting, but it doesn't affect any subsequent thread entry.)
Arctic ice is healthy for children and other living things.
