Long-term observations of daily acoustic travel time along the SAMBA transect at PIES Mooring P2 (September 2013 – July 2015)

Here we present processed travel time from a Pressure-equipped Inverted Echo Sounder (PIES) located at a depth of 2129m at location P2 (34.497°S; 17.301°E) along the South Atlantic MOC Basin-scale Array (SAMBA) transect in the Cape Basin region of the South Atlantic Ocean, between 6 September 2013 and 23 July 2015. TheSouth 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.
