Raw Conductivity-Temperature-Depth (CTD) continuous data collected between 14 July and 17 August 1989 during Voyage 075 on the FRS Africana, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of Southern Africa. ... : Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 14 July and 17 August 1989 during Voyage 075 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 West Coast Hake Biomass Survey were to survey by means of trawling the abundance of adult and recruiting hake in South African waters; to investigate the diurnal cycle of hake and other demersal species; to investigate the environmental and ecological interrelationships of hake and demersal species; to make some experimental trawls in deep water to determine hake distribution limits and to collect deep-water specimens of fish and squid; to collect routine biological material on demersal species from South West African waters; to investigate the ...
