Abstract	This is raw Conductivity-Temperature-Depth (CTD) discrete data from the West Coast Hake Biomass on the Africana Voyage 028, collected between 7 and 30 January 1985. 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 survey by means of trawling the abundance of adult and recruiting hake; to investigate the diurnal cycle and the environment of hake and other demersal species; to compare trawling results of R.S. Africana with those of the Chicha Touza, the Spanish trawler used for similar surveys; to carry out acoustic target identification of mesopelagic species using RMT 8 nets and to retrieve two current meter arrays deployed during Voyage 025.
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. Here we present raw CTD discrete data.
