Here we present processed Conductivity-Temperature-Depth (CTD) discrete data from the upcast collected between 23 May and 13 June 1990, during voyage 082 on the FRS Africana, in the Agulhas Current Large Marine Ecosystem (ACLME) region on the south 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 Coast Demersal Biomass Survey on the Africana Voyage 082 was conducted from 23 May - 13 June 1990. The objectives of the cruise were to survey by bottom-trawling the abundance of adult and recruiting hake, sole and other trawl target species; to make experimental bottom-trawls in deep water to establish the limit of hake distribution, and to collect deep-water specimens of fish and squid; to investigate the environment and ecological interrelationships of hake and other demersal species in the various depth strata; to study demersal community relationships; to investigate the occurrence, distribution and abundance of squid and squid larvae; to investigate the occurrence of line fish species in shallow waters; to study the biology of sharks and skates; to study the biology of kob; and to train senior staff and oceanographic research assistants.
