Abstract	Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 04 August and 29 August 1986, during the Pelagic Winter Survey on the Africana Voyage 047, in the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa and in the Agulhas Current Large Marine Ecosystem (ACLME) on the south 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 main objectives of the cruise were a direct assessment of the biomass of adult anchovy and pilchard on the South and East coasts by acoustic survey, supplemented by aerial fish spotting (East Coast only); an acoustic investigation of the distribution and behaviour of other pelagic fish of commercial importance; an investigation of the relationship between anchovy, pilchard and the hydrobiological environment, specifically water temperature and plankton distribution; a determination of the extent to which anchovy recruits penetrated onto the South Coast, as follow-up to recruit surveys on the West Coast in May and June (Voyages 44 and 45) and a study of the broad physical and chemical features of the Agulhas Bank and East Coast continental shelf in winter.
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.
