Short summary
We analyzed the ability of the ECCO2 reanalysis to represent the hydrographic properties and variability of Antarctic Bottom Water in the Southern Ocean. After 2004, the opening of an oceanic polynya in the Weddell Sea sector and consequent intense dense water production leads to an unrealistic scenario. Even before 2004, bottom waters are warmer and less dense than expected, while the absolute volume transport and velocity estimates are underrepresented.
