Abstract	Here we present raw data from an ADCP, located at a depth of 444m at M9 (34.5032°S; 17.1243°E) along the South Atlantic MOC Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean, between 06 October 2020 and 30 September 2022. 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	The raw data collected from a subsurface mounted, upward-looking, 75 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was configured with a bin size of 16m and a blanking distance of 7.04m, and deployed at a depth of 444m at location M9 (34.5032°S; 17.1243°E), along the South Atlantic MOC Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean. The instrument measured hourly magnitude and direction throughout the water column between 06 October 2020 and 30 September 2022.
