For an overview go here. For ice surface views, go here. For dual ice surface and bedrock views, go here.
No isostatic rebound included in the bedrock views. (When the ice melts, the earth beneath will rise as she is unburdened. This effect is not included in the bedrock depictions here.)
The following is a composite image of ice surface, ice velocity and bedrock, from left to right. Each is detailed below.
The following image is the 100m contours of the ice surface

The following image is a close up of the bedrock below the ice below Nioghalvfjerdsfjorden and Zachariae Isstrom. Note that Zachariae is a wider and deeper connection to the future inland sea.
The following image is a close up of the ice surface along Nioghalvfjerdsfjorden and Zachariae Isstrom. Note that ice is piling up behind the first, but not the second. The warming ocean reaches deeper under Zachariae. Zachariae is a wider and deeper connection to the future inland sea. For discussion of the trough below Zachariae and inlets for Atlantic Intermediate water melting the base of the ice see here.
Bedrock below Dove Bugt, note the areas sparse bathymetry data where
the contours are suspiciously long and straight.

Here are some of Helheim. The first is the velocity from Rignot(2012)

Here are some models of subsurface hydrology in NE Greenland from Lewis(2009) DOI: 10.1002/hyp.7343
