Abstract	Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 02 and 11 March 1989 during Voyage 070 on the FRS Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of Southern 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 Physical-Chemical Oceanography Cruise were to retrieve six acoustic current meters deployed in September 1988; to recover and redeploy the sequentially sampling sediment trap and the two Anderaa current meters incorporated on the array at a position 90 miles west of Walvis Bay; to repeat a line of CTD stations running at right angles to the shelf from the 4000m Cape Basin station towards Conception Bay; to take size-fractional chlorophyll samples at 3-hourly intervals to calibrate the in-line fluorometer in the hydro lab; to collect a Pygmy Right Whale for Peter Best and rare sharks for Len Compagno from Walvis Bay and to exchange scientific equipment at Walvis Bay for the SWA (Namibia) section.
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.
