Yes,the report was from,Geophysical Research Letters,

rg/bzsd (2017).
The E.Antarctic ice sheet may be more vulnerable than previously thought.
The University of Wellington:3-D ice-sheet model predicts greatest warming of the Weddell Sea which will attack the ice sheet at Recovery Basin,which abuts the Sea.

There has been volcanic activity there in the recent past.Tectonic rebound from ice loss is feared to be a potential trigger for additional volcanism,but the main concern will be the warm water eroding the ice from below,at the grounding line.
*the Larsen-A is history
*the Larsen-B is history
*part of the Larsen-C is history
*and another Larsen-C chunk of 50,000 sq-km has fractured,which is 350m thick.
*there are some sub-sea asperities which could tend to hold the sheet,even if it floats off the continent,but it's days are numbered.
*and glaciers which it buttresses will then accelerate into the ocean, for sea-level rise,as they are presently not 'in' the water.
