Physical-Chemical Oceanography Cruise on the Africana Voyage 070, March 1989

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.
