Petermann Glacier 2013

Petermann Glacier 2013

If the feature arrowed in the image below is not a processing artifact, then Petermann Glacier is setting itself up for yet another major calving event.  Further data is needed to support my suggestion that this is either a real fissure or the beginnings of one.

Below is an enhanced image showing that there are possibly two fissures.  I repeat that this new feature needs to be confirmed from other images.
