Abstract	Between 2005 and 2015, multiple short-term studies were conducted to determine the characteristics of moorings deployed in a region heavily influenced by the strong Agulhas Current, and to examine circulation patterns across the continental shelf and slope off Port Edward, along the east coast of South Africa. Three moorings (P1, P2, and P3) were deployed, just south of Port Edward at depths of 36m, 64m, and 162m, respectively, between September 2005 and September 2006, to measure currents and bottom temperatures across the inner shelf. A further three moorings (P4, P5, and P6) were deployed off Port Edward over the period September 2010 to June 2015, at depths of 217m, 1060m, and 2000m, to measure currents and sub-surface temperatures across the outer shelf and slope. Here we present processed daily sub-surface temperatures from two ADCPs at depths of 496 m and 510 m at location P6 (31.1914°S; 30.4499°E) on the outer shelf and slope off Port Edward, between 22 July 2011 and 03 December 2011.
Methods	A sub-surface, upward-looking, 75 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was deployed at location P6 (31.1914°S; 30.4499°E), on the outer shelf and slope of Port Edward, along the east coast of South Africa. A temperature sensor on the instrument measured hourly temperature readings between 22 July 2011 and 03 December 2011, at depths of 496m and 510m. These hourly values were averaged to daily means. Daily values were only generated for days on which there were 75 % or more hourly readings.
