Abstract	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.
