![]() ![]() This sensitivity is primarily related to changes in the flow strength in the cavity inshore of the ridge. ![]() In this paper, we investigate the combined effect of these two processes: how does calving affect the melt rates on PIIS? Using numerical simulations of the ocean flow beneath the ice shelf, we identify a potentially high sensitivity of melt rates to calving, depending on the cavity geometry. However, the ice shelf has also lost large sections from its front in recent years, in a process referred to as calving. The combination of this seabed ridge and ice shelf above it reduce the amount of relatively warm water that is able to reach the ice shelf, therefore restricting the amount of ice shelf melting that can take place. The seabed beneath Pine Island Ice Shelf (PIIS)-the floating extension of Pine Island Glacier-features a large ridge. ![]()
