Previous studies have reported temperature increase of bottom waters in the South Atlantic Ocean at rates of about 2 moC-1. Here we present data indicating four-year warming at rates near the interior of the South Atlantic of up to 17(+/- 0.9) moC-1. The data were sampled from January 2019 to January 2023, at two previously unobserved locations, at 31.13oW and 34.50oS (Site E) and 18.82oW and 34.50oS (Site F). Each mooring was equipped with two independent temperature sensors, one placed 1 m above the seafloor and the other 50 m above. Site E was moored at a nominal depth of 4006 m, under the influence of the Antarctic Bottom Water. Site F was at 3888 m, within a layer influenced by the North Atlantic Deep Water. The data show strong seasonality and significant variability at the semi-diurnal cycle. At both sites, the trends are positive and significant, with the higher rate at the deeper location. Assuming similar surface warming at the convection regions, with the signals being advected to the sampling sites, this could be indicating that climate signals acquired near the surface around Antarctica are reaching the abyssal South Atlantic earlier than those carried by the North Atlantic Deep Water. However, the large spatial heterogeneity and temporal variability of such signals suggest that other local processes are also important in determining the observed temperature variability.
