Abstract	Between 2013 and 2014, a short-term mooring deployment was conducted to determine the oceanographic characteristics and variability off Port St Johns, along the east coast of South Africa. One mooring (PJ) was deployed, at a depth of 95m, between July 2013 and September 2014. This mooring measured currents, as well as sub-surface bottom temperatures on the continental shelf off Port St Johns, on the east coast of South Africa. Here we present processed magnitude and direction of hourly currents throughout the water column (2 - 86 m) from an Acoustic Doppler Current Profiler (ADCP) at location PJ (31.73°S; 29.51°E) on the continental shelf off Port St Johns, between July 2013 and December 2013.
Methods	A bottom-mounted, upward-looking, 300 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was configured with a bin size of 2 m and a blanking distance of 1.76 m, and deployed at location PJ (31.73°S; 29.51°E), on the shelf off Port St Johns. The instrument measured hourly magnitude and direction throughout the water column (4.24 - 90.24 m) between 03 December 2013 and 25 September 2014. These hourly values were corrected for magnetic declination. Only hourly values which showed ≥ 75% good beam data were used.
