Abstract	Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 08 September and 05 October 1987, during the South Coast Hake Biomass Cruise on the Africana Voyage 056, in the southern part of the Agulhas Current Large Marine Ecosystem (ACLME) on the south coast of South Africa and the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South 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. The objectives of the cruise were to survey by means of trawling the abundance of adult and recruiting hake, sole and other trawl target species; to investigate the environment and ecological interrelationships of hake and other demersal species in the various depth strata; to investigate the occurence, distribution and abundance of squid and squid larvae; to investigate the occurence of linefish species in shallow waters; to identify every species caught in the trawl net; and to do chondrichthyian research. Oceanographic research assistants were also trained.
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 profile data.
