Abstract	This is raw Conductivity-Temperature-Depth (CTD) continous data from the South Coast Hake Biomass on the Africana Voyage 036, collected between 15 and 26 October 1985. The cruise operated in the Agulhas Current Large Marine Ecosystem (ACLME) region on the south coast of South Africa. The first objective of this cruise was to establish, by means of surveying and trawling between 200m and 500m water depths, the feasibility of extending the hake biomass surveys to the South Coast. The area 20 E to 25 E, from 75m to 200m water depths, has already been covered during biomass surveys by Japanese research vessels, accompanied on each occasion by one of the Institute's scientists. The feasibility of trawling shallower than 200m in this region, albeit with heavy gear, has thus already been established. The second objective was to investigate, by trawling, the depth distribution of squid in the area 23 30'E and 24 30'E, from as close as possible to the coast (i.e. as shallow as possible) to a depth of 500m.
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.
