Neil Brown MK3 and MK4 Conductivity-Temperature-Depth (CTD) instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000. Here we present processed downcast CTD continuous data collected between 02 and 28 November 1983, during Voyage 013 on the Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa and the Agulhas Current Large Marine Ecosystem (ACLME) on the south coast of South Africa. ... : Neil Brown MK3 and MK4 Conductivity-Temperature-Depth (CTD) instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000. Here we present processed downcast CTD continuous data collected between 02 and 28 November 1983 during Voyage 013 on the Africana. Temperature was converted from the IPTS-68 scale to the ITS-90 scale, and salinity was computed from conductivity measurements on the 1978 Practical Salinity Scale, according to UNESCO (1991) algorithms. UNESCO (1993) quality control procedures were applied to the data, and obvious erroneous values resulting from problems including electronic spikes, data collection in air, inadequate flow through the conductivity cell, among others, have been removed. Any additional calibrations or corrections have been specified in each data file, where applicable and available. ...
