Long-term observations of daily bottom temperatures on the Prince Edward Island shelf at Mooring 1 (May 2022 - April 2023)

Here we present processed daily bottom temperature from an Acoustic Doppler Current Profiler (ADCP) at location M1 (46.770°S; 37.900°E) on the Prince Edward Island shelf, between 10 May 2022 and 25 April 2023. 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.
