Abstract	Here we present processed hourly bottom temperatures from an Acoustic Doppler Current Profiler (ADCP) located at a depth of 305m at M4 (34.2950°S; 17.8802°E) along the South Atlantic Meridional Overturning Circulation (MOC) Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean, between 09 October 2018 and 29 September 2020. The South African component of the international South Atlantic Meridional Overturning Circulation project (SAMOC-SA) aims to characterise the time-mean and time-varying components of the SAMOC in the South Atlantic Ocean and monitor the variability of the main Southern Ocean frontal systems associated with the Antarctic Circumpolar Current (ACC), south of Africa.
Methods	A subsurface-mounted, upward-looking, 150 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was deployed at location M4 (34.2950°S; 17.8802°E), along the South Atlantic Meridional Overturning Circulation Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean. A temperature sensor on the instrument measured hourly temperature readings between 09 October 2018 08h00 and 29 September 2020 19h00, at a depth of 305m.
