Abstract This is processed downcast Conductivity-Temperature-Depth (CTD) continuous data from the West Coast Physical Oceanography cruise on the Africana Voyage 016 collected between 03 and 04 February 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. The objectives of this cruise were to conduct torsional vibration trials to meet the requirements of Lloyds, to retrieve and deploy two thermistor chain/current meter moorings and to conduct CTD profiling in the area of operations.
Methods 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. 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.
