Understanding the Formation of Ice Slabs in the Snow of the Greenland Ice Sheet at De Nationale Geologiske Undersøgelser for Danmark og Grønland (GEUS)

The mass loss from the Greenland ice sheet contributes to about 20% of the current sea level rise. Most of this loss stems from increased melting of the snow and ice at the surface of the ice sheet. It is traditionally thought that most of the melt is produced at lower elevation on the ice sheet and that at higher altitudes the snow could retain any melt like a sponge and prevent meltwater from ending up in the ocean.

Recent field investigations brought to light massive near-surface ice slabs that decrease the ability of snow to retain meltwater. These ice slabs are consequences of the recent climate warming but their formation is not fully understood.

In this project, the student will work with weather station data and a snow model to explain the formation of ice slab at a site in Western Greenland. The results of the study will increase our understanding about ice slabs which is important for the accuracy of the predictions of sea level rise from the Greenland ice sheet.
