Short summary
Totten Glacier in Antarctica holds a sea level potential of 3.85 m. Basal sliding and sub-shelf melt rate have an important impact on ice sheet dynamics. We simulate the evolution of Totten Glacier using an ice flow model with different basal sliding parameterizations and sub-shelf melt rates to quantify their effect on the projections. We found that the modelled glacier retreat and mass loss are sensitive to the choice of basal sliding parameterizations and maximal sub-shelf melt rate.
