Abstract	Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 04 April and 02 May 1989 during Voyage 071 on the FRS Africana in the South Atlantic Ocean and 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 South-east Atlantic Expedition had as its main objectives the investigation of the distribution and abundance of phyllosoma larvae of Jasus in the Cape Basin, a comparative study of larval recruitment of Jasus tristani and Jasus lalandii, and the investigation of the circulation in, and ventilation of, the south western Cape Basin. The work was aimed at improving the understanding of the dynamics, in particular recruitment, of rock lobsters in the South-east Atlantic, and at furthering knowledge about some key large scale physical processes which are thought to be important in regulating the distribution and abundance of a number of exploited stocks in the Benguela region.
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.
