Helheim Glacier is one of Greenland's largest outlet glaciers and is named after the world of the dead in Norse Mythology.[1][2][3]
It feeds the waters of the Helheim Fjord, a branch of the Sermilik (Egede og Rothes Fjord) system, where there are a number of other glaciers calving and discharging at rapid rates such as the Midgard Glacier.[4]

Retreat


Helheim Glacier accelerated from 8 km (5.0 mi) per year in 2000 to 11 km (6.8 mi) per year in 2005.[5] Like many of Greenland's outlet glaciers, it is a common site where glacial earthquakes are monitored.[6]
