Bottom a) temperature (°C) and c) salinity (psu) from the observational climatological mean on the continental shelf over 1975–2012 based on ref. 72 and in the abyss over 1955–2017 based on the World Ocean Atlas 201873) and the equivalent b) temperature (°C) and d) salinity (psu) values in the ACCESS-OM2-01 control run after a 200 year spin-up. All temperatures and salinities shown correspond to the bottom-most value in both observations and the model. Grey contours represent the 4000 m isobath, and the black line denotes the 1000 m isobath around the Antarctic margin.
