Raw CTD continuous observations from the West Coast Physical Oceanography on the Africana Voyage 025, October 1984

This is raw Conductivity-Temperature-Depth (CTD) continuous data from the West Coast Physical Oceanography on the Africana Voyage 025, collected between 25 and 31 October 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 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.
