Our first stop at our Greenland Glacier Summary 2014 is the giant outlet glacier Humboldt Gletscher placed in the Peabody Bugt (bay) in Kane Bassin (basin) which again is a part of Nares Strait. At the same time I will introduce our expert on glaciers and glaciology Professor Mauri Pelto.
 
Mauris report for Humboldt:

The blue dots indicate the snowline, There is one from July of 2011, 2012, 2013 and 2014 plus an August 2014.  This summer like 2013 the sea ice in front of the Humboldt endured into latter July.  The second and most important is that the snowline remained low, and even when it did rise in July it was brief and by early August had already lowered.  Hence, surface melting was limited on the Humboldt compared to any of the years from 2010-2013.  The last image is the Sept 25th image.  The two blue arrows indicate the main fast flow section of the glacier, northern arrow is in the center of the main ice stream, the southern arrow marks an area of crevassing, the southern margin of which is the edge of the fast flow.  This same region is hence the main area of calving at the ice front.  There is no exceptional events on the glacier.  The number of supraglacial lakes is less than most recent years.
Have a ice day!

As Mauri Pelto noted above no exceptional events happened in the season of 2014, which is a very common behavior of Humboldt Gletscher. I will add though, that Humboldt Gletscher is in a ongoing retreat situation as can be seen in the 1975 - 2014 animation below.

Just adding calving line 1975 vs 2014:
