Abstract | Between 2005 and 2014, multiple short-term studies were conducted to determine the circulation patterns across the continental shelf in the vicinity of Algoa Bay, along the southeast coast of South Africa. One mooring (CR01) was deployed off Cape Recife at a depth of 65m, between June 2013 and December 2014. A set of four moorings (ABay01; ABay02; ABay03 and ABay04) were deployed between the mouth of Algoa Bay and the edge of the continental slope, at depths of 75m, 115m, 120m and 160m, between December 2013 and December 2014. A set of three moorings (PA01, PA02 and PA03) were deployed off Port Alfred at depths of 30m, 85m and 165m, between May 2005 and April 2006. The purpose of these moorings were to measure currents and sub-surface temperatures. Here we present processed daily bottom temperatures (153m) from an Acoustic Doppler Current Profiler (ADCP) at location ABay04 (34.27°S; 26.54°E) on the inner shelf off Algoa Bay, between 06 December 2013 and 02 July 2014. |
Methods | A bottom-mounted, upward-looking, 300 kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) was deployed at location ABay04 (34.24°S; 26.54°E), on the shelf of Algoa Bay, along the southeast coast of South Africa. A temperature sensor on the instrument measured hourly temperature readings between 06 December 2013 and 02 July 2014. at a depth of 153m. These hourly values were averaged to daily means. Daily values were only generated for days on which there were 75% or more hourly readings. |
