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.
