Nioghalvfjerdsbrae (79°00′N 025°00′W / 79.000°N 25.000°W / 79.000; -25.000), sometimes referred to as "79 N Glacier", is a large glacier located in northeast Greenland. It drains an area of 103,314 km2 (39,890 sq mi) of the Greenland Ice Sheet with a flux (quantity of ice moved from the land to the sea) of 14.3 km3 (3.4 cu mi) per year, as measured for 1996.[1]

Geography

The glacier has had an 80 km long and 20 km wide floating tongue, widening toward its terminus north of Lambert-Land.[2] There are two calving fronts where the glacier meets the ocean, separated by Hovgaard Island.[3] In August 1997 the southern calving front retreated by 5 km with no significant upstream thinning.[4]
