This study implements a diurnal tidal forcing in an idealized ice-shelf configuration of the Modular Ocean Model 6 (MOM6) to investigate the sensitivity of ice-shelf mass balance to changes in ocean temperature, salinity, tidal amplitude, and tidal phase. We simulate a warm shelf configuration with an evolving shelf boundary fully coupled to the ocean, varying the horizontal resolution to ¼, ½, 1, and 4 km to further investigate the impact of eddies on sub-ice-shelf circulation and mass balance. Shelf melt rate consistently increases while tidal forcing is present. We expect that under higher ocean temperatures and decreased salinity, melt rates will remain largely unchanged, while overturning circulation strength within the cavity decreases. Increasing alongshore and cross-shore tidal amplitude should increase melt rate.
