The Benguela Current Sources and Transport (BEST 1) was conducted on the Africana Voyage 105 from 16 June 1992 to 05 July 1992. The objectives of the survey was the quantification of the flux and Agulhas rings penetrating the South-East Atlantic and the influence of these on the shelf waters and resources of the Benguela system; the provision of a large-scale environmental time-series lasting for a continuous period of 18 months. This was used to validate processes inferred from satellite imagery, thereby enhancing utility of the latter for fisheries environmental monitoring as needed for fisheries research; determination of the distribution and abundance of rock lobster larvae in the South-East Atlantic, to supplement the existing data which were collected in April 1989. This formed an integral part of the Institute's rock lobster research (West Coast rock lobster spend at least one year traversing the South Atlantic gyre before settling on the West Coast); water column and sediment geochemistry on a transect between the coast and the 1000m isobath along 30°27'S to provide an indication of the historical record of anoxia in this part of the Benguela system.

The Current Meter and Sediment Trap Recovery Shelf Chemistry on the Africana Voyage 114, June 1993 was conducted from 21 June 1993 to June 30 1993. The main objectives of the cruise were to recover and redeploy the inshore time series current meter array deployed in 168m off Cape Columbine. To locate and attempt recovery of the inshore current meter deployed in 132m off Hondeklip Bay; to locate and attempt recovery of the offshore current meter sediment trap array deployed in 686m off Hondeklip Bay; to attempt location and recovery of the offshore current meter array deployed in 278m off Cape Columbine. To conduct research into the shelf geochemistry on a line off Hondeklip Bay and, if time, in St Helena Bay and to conduct a survey of nearshore dissolved oxygen in the vicinity of Port Nolloth to link in with research on Namagualand stocks being undertaken by the Rock Lobster section.

The Physical-Chemical Oceanography Cruise was conducted on the Africana Voyage 077, from 11 - 22 September 1989. There were several objectives to this cruise, covering Physical Environment (PE), Sedimentation and Nutrient cycling (SN), Chemical Environment (CE), Shoal Ecology (SE), Plankton studies (P) and testing of the new AIDA acoustic system with possible estimates of biomass in specific places such as in the baroclinic jets. The cruise objectives included identifying and documenting near-surface and mid-water baroclinic jets west of Cape Columbine and Cape Town using acoustic doppler profiling and Conductivity-Temperature-Depth (CTD) data; observing currents in the upper 200m at regular intervals along the cruise track, using the Acoustic Doppler Current Profiler (ADCP); performing a 30 hour internal tide experiment at the shelf edge west of the Chamais Bay; deploying a series of current meter moorings on the Namibian remote shelf and eastern Cape Basin zones between Chamais Bay and Walvis Bay; servicing a weather station at Pelican Point; recovering a current meter array 90 miles west of Walvis Bay and re-deploying the Kiel sediment trap and current meter array at the same position; deploying the ruggedised Sea Fisheries Research Institute (SFRI) sediment traps in the vicinity of the Orange River and Conception Bay; taking box cores for on-board sediment core incubation at Conception Bay and the same Orange River Mouth site sampled in March 1989; running a set of CTD lines across the shelf to the vicinity of the shelf break; and lastly to draw samples from the labratory seawater sampling probe at regular intervals for fractionation, filtration and calibration of the in-line fluorometer.

The Physical-Chemical Oceanography Cruise was conducted on the Africana Voyage 067 from 14 - 30 September 1988. This cruise was divided into two legs with the first leg focusing on physical oceanography and the latter on chemical oceanography. The purpose of the first leg of the cruise was primarily to moor current meters and water-level recorders at various sites, mostly north of the Orange River, and to obtain a precise set of Conductivity-Temperature-Depth (CTD) data on a line running normal to the topography from a point in 4200m of water into Conception Bay. The CTD data will be used to calculate water flux along the shelf using inverse techniques. The objectives of the second leg included deploying the Kriel sequential sediment trap west of Walvis Bay, recovering Sea Fisheries Research Institute (SFRI) sediment traps deployed in the first half of the cruise, investigating trends in primary production in the vicinity of the Kriel trap mooring and around upwelling centres using C-14 deck incubations and conducting box coring and hydrological sampling to investigate the high carbon loading of the South West Africa (Namibia) shelf sediments.

The Physical-Chemical Oceanography Cruise was conducted on the Africana Voyage 070 from 2 - 11 March 1989. The objectives of the cruise were to retrieve six acoustic current meters deployed in September 1988; to recover and redeploy the sequentially sampling sediment trap and the two Anderaa current meters incorporated on the array at a position 90 miles west of Walvis Bay; to repeat a line of Conductivity-Temperature-Depth (CTD) stations running at right angles to the shelf from the 4000m Cape Basin station towards Conception Bay; to take size-fractional chlorophyll samples at 3-hourly intervals to calibrate the in-line fluorometer in the hydro lab; to collect a Pygmy Right Whale for Peter Best and rare sharks for Len Compagno from Walvis Bay and to exchange scientific equipment at Walvis Bay for the SWA (Namibia) section.
