Long-term observations of hourly bottom temperatures on the Prince Edward Island shelf at Mooring 1 (April 2021 - May 2022)

Here we present processed hourly bottom temperature from an Acoustic Doppler Current Profiler (ADCP) at location M1 (46.773°S; 37.912°E) on the Prince Edward Island shelf, between 26 April 2021 and 06 May 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.
