Over the entire simulation period, the system shows stick-slip behavior under stress-controlled conditions where velocities range from 0 to $\sim$9 km/d with strong hysteresis (Fig.~\ref{fig:hysteresis}a).
The response during the first cycle ($t<1$ d) is slightly different from later cycles ($t>1$ d) as the model is initialized with a hydrostatic water-pressure distribution.
-Under rate-controlled conditions, the shear stress varies linearly as predicted for Mohr-Coulomb materials but with slight hysteresis at high effective normal stresses (Fig.~\ref{fig:hysteresis}d).
+Under rate-controlled conditions, the shear stress varies linearly as predicted for Mohr-Coulomb materials but with hysteresis at high effective normal stresses (Fig.~\ref{fig:hysteresis}d).
Both driving modes produce deep deformation during periods where water-pressure at the ice-bed interface is at its lowest magnitude.
Under stress-controlled conditions, the deep deformation produces an insignificant amount till flux (Fig.~\ref{fig:hysteresis}c), as the shear stress at this time as the shear stress is insufficient for slip (Fig.~\ref{fig:hysteresis}a).
Instead, the majority of sediment transport occurs as shallow deformation during rapid slip events and high water pressures (Fig.~\ref{fig:hysteresis}b,c).
