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 90m, 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 raw data from an ADCP at location PJ (31.73°S; 29.51°E) on the continental shelf off Port St Johns, between December 2013 and September 2014.
Methods The raw data was collected using 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 between 02 July 2013 and 03 December 2013.
