Color-mapped oxygen concentrations, with neutral density contours (γn) overlain, as drawn from the 2013 World Ocean Atlas69,70. Sediment cores presented here (ODP Site 1094, PS1768-8 and PS1599-3) are marked with red circles. The locations of other cores mentioned in the text are marked as white squares in the inlet map. The isopycnal with a neutral density of 28.27 kg m−3 defines the water mass boundary between AABW and LCDW, while the 28.18 kg m−3 isopycnal defines the top of Antarctic Circumpolar Current bottom water as defined in Orsi et al.18. Figure created with Ocean Data View71. AABW: Antarctic Bottom Water; LCDW: Lower Circumpolar Deep Water; NADW: North Atlantic Deep Water.
