Short summary
Antarctica's ice shelves are melting from below as ocean currents bring warm water into the ice shelf cavities. The melt rates of the large Filchner–Ronne Ice Shelf in the southern Weddell Sea are currently low, as the water in the cavity is cold. Here, we present data from a scientific cruise to the region in 2021 and show that the warmest water at the upper part of the continental slope is now about 0.1°C warmer than in previous observations, while the surface water is fresher than before.
