Supplementary Information:


A standard numerical experiment featuring the Ross Ice Shelf, Antarctica, is presented as a test package for the development and intercomparison of ice-shelfmodels. The emphasis of this package is solution of stress-equilibrium equations for an ice-shelf velocity consistent with present observations. As ademonstration, we compare five independently developed ice-shelf models based on finite-difference and finite-element methods. Our results suggest thatthere is little difference between finite-element and finite-difference methods in capturing the basic, large-scale flow features of the ice shelf. We additionallyshow that the fit between model and observed velocity depends strongly on the ice-shelf temperature field for which there is presently little observationalcontrol. The main differences between model results are due to the equations being solved, the boundary conditions at the ice front and the discretisationmethod (finite element vs. finite difference)
