The Scar project hopes to understand the nature of the "scar" features surrounding Ice Stream C in order to best interpret the ice flow history in the last millennia. Also, we are interested in understanding what controls the positions of ice streams. In particular, what role do the interstream ridges play in controlling ice flow in this area. Finally, we hope to use this information to infer ice sheet thickness changes over the last few centuries.
