a The Antarctic Circumpolar Current (ACC) system around the Antarctic and this study region (red box) at the tip of the Antarctic Peninsula. b Close-up of the study region showing the bathymetry, seismic lines, and the Bransfield Current (BC) system in the Bransfield Strait (BS). The numbered gray lines are the seismic sections with blue starting points. The red point is the start of the entire seismic acquisition. The black sub-sections are shown in Fig. 3, and the orange parts are the locations of the seismically constrained Bransfield Current. The numbered curves are the ① Bransfield Current, ② Bransfield Current Recirculation, ③ Circumpolar Deep Water (CDW), ④ Transitional Bellingshausen Water (TBW), ⑤ Transitional Weddell Water (TWW), and ⑥ Peninsula Front (PF). c Latitude as a function of time showing the progression of the seismic acquisition during the cruise in 1991. BLS Bellingshausen Sea, WDS Weddell Sea, ESB eastern sub-basin, CSB central sub-basin, WSB western sub-basin. SAF Sub-Antarctic Front, ACCPF ACC Polar Front, SACCF Southern ACC Front, SB Southern Boundary.
