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 magnitude and direction of hourly currents throughout the water column (47.48 - 247.48 m) from an ADCP at location M2 (46.7117°S; 37.902°E) on the Prince Edward Island shelf, between 21 April 2018 and 05 May 2019.
Methods A bottom-mounted, upward-looking, 150 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was configured with a bin size of 8 m and a blanking distance of 3.52 m, and deployed at location M2 (46.7117°S; 37.902°E), on the shelf between Marion Island and Prince Edward Island. The instrument measured hourly magnitude and direction throughout the water column (47.48 - 247.48 m) between 21 April 2018 14h00 and 05 May 2019 12h00. These hourly values were corrected for magnetic declination and only hourly values which showed ≥ 75 % good beam data were used.
