THE intimate thermal contact between the base of Antarctic ice shelves andthe underlying ocean enables changes in climate to have a rapid impact on theoutflow of ice from the interior of Antarctica1,2. Furthermore,water modified by passage under ice shelves, particularly in the Weddell Sea,is believed to be an important constituent of Antarctic BottomWater3—a water mass that can be observed as far north as 50°N in the deep oceans4. Antarctic Bottom Water is both cold andoxygen-rich, and plays an important part in the cooling and ventilation of theworld’s oceans. Because of the difficulty in gaining access, the oceano-graphicregime beneath ice shelves is very poorly sampled5. Bysuccessfully drilling through the ice, however, we were able to obtainoceanographic data from beneath the largest Antarctic ice shelf, theRonne–Filchner ice shelf in the southern Weddell Sea. We find that our dataagree well with the predictions of a relatively simple oceanographic plumemodel of sub-ice-shelf circulation6. This model can therefore beused with some confidence to investigate the links between climate changes,ice-shelf melting and bottom-water production.
