Abstract 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. Here we present processed hourly bottom temperatures from an Acoustic Doppler Current Profiler (ADCP) located at a depth of 304m at M4 (34.2942°S; 17.8803°E) along the South Atlantic MOC Basin-wide Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean, between 10 July 2014 and 10 December 2014.
Methods A subsurface-mounted, upward-looking, 150 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was deployed at location M4 (34.2942°S; 17.8803°E), along the South Atlantic MOC 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 10 July 2014 00h00 and 10 December 2014 09h00, at a depth of 304m. The data were then formatted in a .txt file with data values separated by commas.
