Abstract	The objectives of this cruise included studying shelf circulation in the vicinity of Port Nolloth by placing three current meter moorings across the shelf; exploring the deep circulation in the Cape Basin which is thought to be a driving mechanism for the preponderance of southward flow observed on the shelf by placing a current meter in 3000m of water; recovering one current meter in the Cape Canyon and deploying two current meter moorings and a thermistor string near Cape Columbine and obtaining Conductivity-Temperature-Depth (CTD) data at these sites; collecting chemical samples and CTD data along a line between Port Nolloth to the deep current meter site, this included 100ml samples for analysis by M.J. Orren on routine CTD casts; a line of six coastal CTD stations was to be worked in the Hondeklipbaai upwelling tongue; the surface flow over the 1000m contour was to be studied using an acoustic drifter and samples were to be taken at various CTD stations for nitrogen cycling studies.
