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 King Frederick VIII Land, northeastern 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] The glacier has two calving fronts where the glacier meets the ocean, separated by Hovgaard Island.[2] In July 2020, the northern offshoot, the Spalte Glacier broke away from Nioghalvfjerdsbrae and completely disintegrated.[3]
