Fig. 1

Model bathymetry (color) and initial release locations of tracers representing Circumpolar Deep Water (CDW) (orange and purple boxes). Bathymetric contours of 500, 1500, 3000, and 4000 m are shown with black contours. The inset (right bottom) shows Antarctica with the region surrounded by black line denoting the model domain. The red line represents the vertical section shown in Fig. 2. White arrows indicate the Ross Gyre and the southern extent of the Antarctic Circumpolar Current (ACC)1. CDW tracers are integrated in the Amundsen Sea (AS) and Bellingshausen Sea (BS) domains enclosed by cyan lines indicating the continental shelf regions south of 700 m isobaths along continental shelf break. The time series of area-averaged CDW temperature and heat content for the eastern AS region are calculated for the region enclosed by the gray line. AS and BS denote the Amundsen Sea and Bellingshausen Sea. Letters E and C denote the submarine glacial troughs located on the eastern and central AS continental shelf, respectively. Locations of ice shelves are shown with white patches and acronyms are summarized in Supplementary Table 3
