[1] The North-East Greenland Ice Stream (NEGIS) discharges into 3 main marine-terminating outlets: 79N Glacier, Zachariae Isstrøm and Storstrømmen – as arranged North to South.

This is suggested as this outlet sits on higher elevations, where the subglacial topography and hydro-dynamics pin and slow glacier flow, relative to predominantly marine-based 79N and Zachariae Isstrøm.

All 3 outlets see an increased ice velocity in the summer months,[4] as surface meltwater is fed into the subglacial environment, saturating highly-malleable tills and lubricating the over-riding glacier's movement.

Grounding-line retreat is noted by the same article to be approximately 400m/yr, and the "dynamic cycling" of temperature and precipitation (which alters glacier mass-balance) is thought to be causing this.

The nunataks present a viable albedo-feedback mechanism, which preferentially forms supraglacial lakes at the margins of many of the outlets in the area.
