Long-term observations of daily bottom currents along the SAMBA transect at PIES Mooring P1 (July 2017 – September 2019)

Here we present processed northward and eastward velocity components from a 2000 khz Aanderaa Doppler Current Sensor (DCS) deployed at a depth of 1261m at location P1 (34.408°S; 17.550°E) along the South Atlantic MOC Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean, between 27 July 2017 and 29 September 2019. 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.
