Morning Tim!
It is not my intention to spoil your hard work on spotting all GIS changes. I've done the same over the years, as I believe FI Espen does, or Mauri Pelto on 'From a glaciers perspective'.
But I think the difference you refer to doesn't relate to major calving at this point of the season.
Fjords like this often show dramatic shifts in the content of ice debris, especially during the winter season.
In my opinion, the right time to watch for differences is about July, when most snowdecks have melted and the cryosphere remains have better properties on MODIS to interpret their quality.
I'm looking forward to do a new contour survey this year. The comparison to those of '09 and '12 will give an indication what has been the effect of a small meltseason ('13), a 'normal' one ('14) and the spring to come.
Look for the post on this glacier on the Greenland icesheet retreat thread to see what the comparison '09 to '12 produced on this area.
