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 hourly sub-surface temperatures from an ADCP at a depth of 210m at location P4 (31.1095°S; 30.3072°E) on the outer shelf and slope off Port Edward, between 21 July 2011 and 07 October 2011. |
Methods | A sub-surface, upward-looking, 150 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was deployed at location P4 (31.1095°S; 30.3072°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 21 July 2011 18h00 and 07 October 2011 06h00, at a depth of 210m. |
