Long-term observations of daily acoustic travel time along the GoodHope transect at PIES Mooring GH03 (July 2015 – December 2018)

Here we present processed travel time from a Pressure-equipped Inverted Echo Sounder (PIES) located at a depth of 5070m at location GH03 (37.4076°S; 12.5187°E) along the GoodHope transect in the Cape Basin region of the South Atlantic Ocean, between 25 July 2015 and 17 December 2018. 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.
