Abstract The dataset includes model simulation results of the tsunami impact on the Ross Sea Ice Shelf, specifically the time sequence of the water surface elevation of the tsunami, generated by circum-Pacific-Rim subduction zone earthquakes. The model simulations utilized the boundary conditions provided by the Pacific-wide simulations.
