Nuusuaq Peninsula West Greenland Glacier Disintegration

Comparison of alpine glaciers on Nuussuaq Peninsula in 1990 and 2016 Landsat images.  Each arrow is at a specific location in both images exhibiting glacier separation/disintegration.  The Nuussuaq Peninsula is just north of Disko Island in West Greenland and is home to many alpine glaciers and small ice caps.  Here we examine the furthest west group of alpine glaciers on the peninsula.  This group is 125 km west of the ice …
