Raw Acoustic Doppler Current Profiler (ADCP) data for long-term observations of currents at SAMBA Mooring 4 (October 2018 - September 2020)

Here we present raw data from an Acoustic Doppler Current Profiler (ADCP), deployed at a depth of 320 m 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 10 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.
