| Abstract | Here we present processed Conductivity-Temperature-Depth (CTD) discrete data from the downcast collected between 08 March and 25 March 1997, during voyage 143 on the Africana, in the Benguela Current Large Marine Ecosystem (BCLME) on the west coast of Southern Africa and in the Agulhas Current Large Marine Ecosystem (ACLME) on the south coast of Southern Africa. Neil Brown MK3 and MK4 CTD instruments were used to measure pressure, temperature and conductivity through the water column during research and monitoring cruises between 1983 and 2000. |
| Methods | 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. |
