Processed CTD continuous observations from the Plankton Shoal Ecology cruise on the Africana Voyage 020, May 1984

This is processed downcast Conductivity-Temperature-Depth (CTD) continuous data from the Plankton Shoal Ecology cruise on the Africana Voyage 020 collected between 21 May and 29 May 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. This Plankton Shoal Ecology cruise is the second of two and comprised an extensive grid (stations E01-E14), an intensive grid (stations SH01-12 to SH05-24) and a 1x1 nautical mile box grid for time series sampling (stations TS01-18 to TS03-18). Sample data was only collected at the SH and TS stations.

Processed CTD discrete observations from the West Coast Physical Oceanography cruise on the Africana Voyage 019, May 1984

This is processed Conductivity-Temperature-Depth (CTD) discrete data from the West Coast Physical Oceanography cruise on the Africana Voyage 019 collected between 7 and 17 May 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. Africana Cruise 019 lasted from May 7 to May 17th 1984 and undertook several scientific tasks. The first part of the cruise was mostly devoted to bathymetric and geophysical (continuous reflection seismic) surveys in the region of the Cape Canyon of SW Cape. These surveys were the responsibility of personnel from the Marine Geoscience Unit of the University of Cape Town, and were done as part of a collaborative project with officers of the Sea Fisheries Research Institute who have an interest in the physiography of the Canyon and adjacent areas. The project received nominal financial support during 1984 from the SANCOR CSP Marine Sedimentology Programme.

Processed CTD discrete observations from the Shoal Ecology Cruise on the Africana Voyage 018, April 1984

This is processed Conductivity-Temperature-Depth (CTD) discrete data from the Shoal Ecology Cruise on the Africana Voyage 018 collected between 9 and 19 April 1984. 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 obtain a broad picture of pelagic fish shoal distribution in relation to the prevailing mesoscale environmental features; to investigate intensively the diel shoal behaviour pattern of anchovy, pilchard and round herring, with particular reference to their feeding behaviour in relation to food supply. If time permitted the plan was to carry the investigation out in two areas of contrasting environmental features ie St Helena Bay and off Saldanha Bay. Shoals of fish close to strong environmental gradients (in a horizontal plane) will be surveyed to investigate the effect, if any, upon diel behaviour patterns on either side of the gradient. A number of extended lines,...

This is processed CTD discrete data from the upcast collected during the West Coast Hake Biomass Survey on the Africana Voyage 015 from 05 - 31 January 1984. The cruise operated in the Benguela Current Large Marine Ecosystem (BCLME) region on the west coast of South Africa. The purpose of this cruise was to survey by means of trawling the abundance of recruiting and adult hake between the Orange River and longitude 20° E. The objectives also included investigating the diurnal cycle of hake and other demersal species, to compare the trawling results of R.S. Africana with those of M.F.V. Chicha Touza, the Spanish trawler used for similar surveys, to investigate the environment of hake and other demersal species and to carry out acoustic target identification of mesopelagic species using RMT 8 nets.
