a Reflection of Line C04 (i.e., Line 04 in the central sub-basin in Fig. 1). b A seismic interpretation of the water structure based on the regional hydrographic observations. Two fronts are Bransfield Front (BF) and Peninsula Front (PF). Due to the seismic survey geometry, data are missing at depths shallower than ~100 m. Therefore, the surface PF is inferred based on the distribution of TBW and TWW water masses. The black lines at the bottom right corner show a dip angle reference. The amplitudes of the seismic data in (b) are a factor of 0.5 of those in (a). The topographic names are South Shetland Islands (SSI) Slope on the northwest side and Antarctic Peninsula (Ant. Pen.) Shelf/Slope on the southeast side.
