Long-term observations of daily acoustic travel time along the GoodHope transect at PIES Mooring GH01 (December 2014 – July 2015)

Here we present processed travel time from a Pressure-equipped Inverted Echo Sounder (PIES) located at a depth of 4562m at location GH01 (35.2606°S; 14.0440°E) along the GoodHope transect in the Cape Basin region of the South Atlantic Ocean, between 6 December 2014 and 24 July 2015. 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.
