Tracking the surface conditions of the Greenland ice sheet from space hos 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 increasing melt of the snow and ice at the surface of the ice sheet. Owing to the immensity of the ice sheet, spanning over more than 20 degrees of latitude and from sea-level to more than 3000 m, we can divide it into multiple regions, or facies, based on surface conditions and summer melt.

The location and size of these regions are precious climate indicators and, with a changing climate, some of these facies may have been migrating, growing or shrinking. But in spite of the numerous remote-sensing products available, no consistent mapping of these facies has been conducted to this date.

The student will have to work with multiple remote sensing products, making use of existing algorithm to map facies across the ice sheet and study the spatio-temporal evolution of these facies since the beginning of the satellite era.
