Short summary
The speed at which Antarctic ice flows is dependent on its viscosity and the slipperiness of the ice/bedrock interface. Often, these unknown variables are inferred from observations of ice speed. This article presents an attempt to make this difficult procedure easier by making use of additional information in the form of observations of crevasses, which make ice appear less viscous to numerical models. We find in some circumstances that this leads to more appealing solutions to this problem.
