Raw CTD continuous observations from the South Coast Hake Biomass Survey on the Africana Voyage 048, September 1986

Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 12 September and 03 October 1986, during the South Coast Hake Biomass Cruise on the Africana Voyage 048, in the southern part of the Agulhas Current Large Marine Ecosystem (ACLME) on the south coast of South 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 objective of the cruise was to survey by means of trawling the abundance of adult and recruiting hake, sole and other trawl target species; an investigation of the environment and interrelationships of hake and other demersal species in various depth strata; to investigate the occurence, distribution and abundance of squid and squid larvae; and to investigate the occurence of linefish species in shallow waters.
