description: 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.
description: 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 occurence, distribution and abundance of squid and squid larvae; to study demersal community interrelationships; to study the biology of sharks and selected non-commercial fish species; to investigate zooplankton scattering layers and their influence on the feeding behaviour of small hake and to extend the primary production data further offshore as well as north and eastwards from the Cape Peninsula - Cape Columbine area.

title: Raw CTD continuous observations from the West Coast Hake Biomass Survey on the Africana Voyage 069, January 1989

description: Raw Conductivity-Temperature-Depth (CTD) continuous data collected between 05 and 26 January 1989 during Voyage 069 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 West Coast Hake Biomass Survey was multi-disciplinary. The main target was to determine, by means of the swept area method, the present status of the hake resource on the South African west coast. In carrying out this study, it was possible also to collect some information on the environment and zooplankton (including squid larvae) in the vicinity of the catches and to determine some ecological interrelationships of hake and other demersal fish species, to investigate squid distribution, to study some aspects of the biology and distribution of sharks and skates, to study the feeding ecology of demersal species of little commercial importance and to look closely at demersal communities. A diurnal study was also carried out successfully and some deep-water trawls were made to collect rare and interesting specimens. While in South West African waters, a comparison of the trawling capabilities of the M.F.V. Chica Touza and R.S. Africana was attempted and much biological material was collected for routine studies of demersal fish in those waters. Throughout the cruise, otoliths and squid beaks were collected for stomach content studies, and in-depth research was conducted into horse mackerel.

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-east Atlantic Expedition had as its main objectives the investigation of the distribution and abundance of phyllosoma larvae of Jasus in the Cape Basin, a comparative study of larval recruitment of Jasus tristani and Jasus lalandii, and the investigation of the circulation in, and ventilation of, the south western Cape Basin. The work was aimed at improving the understanding of the dynamics, in particular recruitment, of rock lobsters in the South-east Atlantic, and at furthering knowledge about some key large scale physical processes which are thought to be important in regulating the distribution and abundance of a number of exploited stocks in the Benguela region.
