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.

Shoal Ecology on the Africana Voyage 018, April 1984

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, traversing the gradient will be steamed with plankton and fish being sampled on an ad hoc basis. It could well be that this investigation would be given a higher priority than the intensive survey off Saldanha.

Pre-processed chlorophyll-a data from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 218, September 2015

This is pre-processed chlorophyll-a data from the St Helena Bay Monitoring Line September 2015 cruise (now under the Integrated Ecosystem Programme: Southern Benguela). The St Helena Bay Monitoring Line was initiated as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims are to obtain seasonal and interannual information on the hydrology and productivity of the area. Data on harmful algal blooms, low oxygen water and intrusions of Agulhas Bank water along the west coast will also be collected. A long-term, multi-decadel time-series (from 1951 onward) of information already exists for this important region and has continued in the form of the IEP:SB to detect long-term changes in the hydrology and the plankton, which are important for the detection of regime shifts.
