Figures and Tables
Figure 1 . Circulation and topography in the East Antarctic margin. The 3,000 m isobath is highlighted in white. Polar Front (PF; green), Northern/southern branches of Southern ACC Front (SACCF-N/S; yellow/magenta), and subpolar gyres (blue) are derived from dynamic ocean topography (Section 3.1), and Southern Boundary (SB; red) and Antarctic Slope Front (ASF, by 0°C at 400 dbar; cyan) are reproduced from temperature field of a climatological dataset by Shimada et al. (2017). The SACCF-S corresponds to the southernmost eastward jet of ACC (~4,000 m isobath), whereas the SB is located along the center of subpolar recirculating gyres (4,000–3,000 m) about zero lines of zonal velocity.
