Abstract	This is raw Conductivity-Temperature-Depth (CTD) continuous data from the Coastal Current Meter Programme on the Africana Voyage 017 collected between 19 and 27 March 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 retrieve ten moorings, eight on the shelf and two on the shelf break between Cape Columbine and Port Nolloth; to deploy three moorings in the coastal zone between Cape Columbine and Cape Town; to obtain Conductivity-Temperature-Depth (CTD) profiles and water samples on a transect bearing 270° from Cape Columbine; to profile currents, make repeated CTD casts and record atmospheric conditions in St Helena Bay as part of a vertical mixing study, participating in this work were two scientists from UCT; to calibrate the CTD temperature probe in-situ using reversing thermometers; to allow the chemical oceanography team to familiarise themselves with the operation of a new box corer and enable them to analyse intact sediment samples from St Helena Bay; to use the thermosalinograph and fluorometer to obtain 'surface truth' measurements for NOAA thermal infra-red imagery; to test a portable CTD unit to 50m and lastly to train two new members of technical staff.
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.
