In the new paper, the authors identify potential oceanic gateways to Antarctic grounding lines based on high-resolution bathymetry data and examine the effect of access depths on ice-shelf melt rates. The identified gateways manifest the deepest topographic features that could channel warm water masses to the base of the ice sheet. They find oceanic gateways in several Antarctic regions and estimate an upper bound of melt rate changes in case warm water masses at intermediate depth gain access to the ice shelf cavities.
