Abstract	Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 05 November and 30 November 1987, during the Anchovy and Pilchard Spawning Stock Survey on the Africana Voyage 057, 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 main objective of the cruise was to determine acoustically the biomass of the pilchard and anchovy spawning stocks between Hondeklip Bay and the eastern end of the Agulhas Bank. Additionally, the relationship between the distribution of pelagic fish, their eggs and the water temperature was investigated, and chemical samples were taken along lines of stations as part of an ongoing investigation with the supply of nutrients to the Agulhas Bank.
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.
