Abstract This is raw Conductivity-Temperature-Depth (CTD) discrete data from the West Coast Hake Biomass on the Africana Voyage 033, collected between 1 and 21 July 1985. 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 survey by means of trawling the abundance of adult and recruiting hake; to investigate the diurnal cycle of hake and other demersal species; to investigate the environment and ecological interrelationships of hake and other demersal species and to carry out acoustic target identification of mesopelagic species with RMT 8 nets.
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 discrete data.
