title: Processed CTD discrete observations from the West Coast Hake Biomass Survey on the Africana Voyage 054, June 1987

description: Africana Voyage 054
description: Here we present processed Conductivity-Temperature-Depth (CTD) discrete data from the upcast collected between 16 June and 10 July 1987, during the West Coast Hake Biomass Cruise on the Africana Voyage 054, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west 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 scientific targets of the trip revolved around the determination of biomass index of both Cape hake species off the South African west coast. The diurnal cycle of Cape hake and their relationship with environmental parameters was also studied. Some hake material were collected in South West African waters. Deep-water trawls were made to delimit the offshore extent of hake distribution and to collect rare specimens of fish for accession to museums. Demersal community interrelationships were studied, as were spatial distribution patterns and spawning fractions of round herring.
description: 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. Temperature was converted from the IPTS-68 scale to the ITS-90 scale, and salinity was computed from conductivity measurements on the 1978 Practical Salinity Scale, according to UNESCO (1991) algorithms. UNESCO (1993) quality control procedures were applied to the data, and obvious erroneous values resulting from problems including electronic spikes, data collection in air, inadequate flow through the conductivity cell, among others, have been removed. Any additional calibrations or corrections have been specified in each data file, where applicable and available.

title: Raw CTD continuous observations from the West Coast Hake Biomass Survey on the Africana Voyage 050, January 1987

description: Africana Voyage 050
description: Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 06 January and 31 January 1987, during the West Coast Hake Biomass Cruise on the Africana Voyage 050, in the Benguela Current Large Marine Ecosystem (BCLME) region on the west 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 objectives of the cruise were to survey by means of trawling the abundance of adult and recruiting hake; to investigate the the diurnal cycle of hake and other demersal species; to investigate the environment and interrelationships of hake and other demersal species; to establish the offshore limit of hake and monkfish distribution and to collect deep-water specimens of fish and cephalopods; to conduct mouth-opening experiments with transducers on each wing of the net, and to compare the mouth opening and fishing capabilities of V doors and Polyvalent doors; to study community interrelationships and assemblages and to collect data on hake and other species from the International Commission for the South-East Atlantic Fisheries (ICSEAF) Division 1.5, ie: north of the South African border.

title: Processed CTD discrete observations from the West Coast Hake Biomass on the Africana Voyage 039, January 1986

description: Africana Voyage 039
description: This is processed Conductivity-Temperature-Depth (CTD) discrete data from the West Coast Hake Biomass on the Africana Voyage 039, collected between 08 January and 05 February 1986. 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; to carry out acoustic target identification of mesopelagic species with RMT 8 nets; to make a few experimental trawls in deep water to search for the other species of monkfish and to determine the offshore limit of hake distribution; if possible to rendezvous with Spanish and Soviet vessels and to carry out standardisation trawls in parallel and to conduct net mouth-opening experiments with transducers on each wing of the net.

title: Raw CTD continuous observations from the Anchovy Recruitment on the Africana Voyage 047, August 1986

description: Africana Voyage 047
description: Here we present raw Conductivity-Temperature-Depth (CTD) continuous data collected between 04 August and 29 August 1986, during the Pelagic Winter Survey on the Africana Voyage 047, in the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa and in 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 main objectives of the cruise were a direct assessment of the biomass of adult anchovy and pilchard on the South and East coasts by acoustic survey, supplemented by aerial fish spotting (East Coast only); an acoustic investigation of the distribution and behaviour of other pelagic fish of commercial importance; an investigation of the relationship between anchovy, pilchard and the hydrobiological environment, specifically water temperature and plankton distribution; a determination of the extent to which anchovy recruits penetrated onto the South Coast, as follow-up to recruit surveys on the West Coast in May and June (Voyages 44 and 45) and a study of the broad physical and chemical features of the Agulhas Bank and East Coast continental shelf in winter.
