    New Cracks In Pine Island Glacier

    A huge crack which was discovered last October in Pine Island Glacier has propagated into a series of cracks during the Antarctic Winter.  The recent satellite image below shows the new cracks.  Newer images will no doubt show these cracks more clearly as the sun rises higher in the Antarctic skies.  The animation below helps to demonstrate the great advance of the glacier front and the propagation of the cracks since February 2012.

    Pine Island Glacier March 2012 and September 2012 compared.

    Given the amount of crack propagation during the Antarctic Winter, it is highly likely that we shall see a dramatic calving event in the forthcoming Antarctic Summer.

    The image below shows the crack as it was when originally discovered.

    "This image from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NAS's Terra spacecraft was acquired Nov. 13, 2011, and covers an area of 27 by 32 miles (44 by 52 kilometers), and is located near 74.9 degrees south latitude, 101.1 degrees west longitude."

    my brother and i love this one - it's like watching our racist Media trying to get up on a High Horse and lecture any of us about being honest *LOL* oh yes, that glacier is melting.

    I almost feel like apologizing that one of your first responses should be simple incoherent babbling.

    what you're learning about in all of your putatively Grand Understanding is what we call "a Standpoint". however, bear with us - i gather already that you are so far beyond learning anything else in your Perfection ^^ the point is not so much your assessment but rather the plain existence of many different points-of-view.

    you can now yammer on about this response Gierhardt :)

    I can't comprehend a mind that is so feeble that it spells my name wrong despite it being written in the post previous.

    *chuckle* exactly. ^^

    After all those pinked-out comments, this is not someone trying to sell you something.
    However, I do just happen to have some of these ...

    There is the predictive uncertain science,but there are also gifted scientists who are able to read the modelling correctly relying not just on the science but their inherent gift as well.These two things can make the predictions reasonably certain,anyone who has seen the movie "Dante's Peak" will know what i mean.I would be very interested Patrick if you could use your gift as well as your science to plot the likely path of such a huge ice burg should it break away from the p.i,g .The Trolltunga:path1967-78 floated out to south Georgia and into the circumpolar current,where it would certainly have a cooling effect and possibly change weather patterns off south Africa,south Australia,New Zealand and South America.see link

    When it calves, how many Manhattans are we talking? 50? That would be like 10 times Petermann-2010, right?
    Good to see you back Patrick.
