Work was started off Benguela on 30 April. Sampling of pelagic fish with midwater trawl were made during nighttime, wheras attempts were made to cover important aggregations of small pelagic fish acoustically both by day and by night. The prepositioned bottom trawl hauls on the shelf were all made during daylight hours and distributed at intervals over the total accessible depth range. Most of the hauls in the deeper range of the slope were only made during nighthours. South of Luanda two hydrographic profiles were worked, one off Lobito and another off Ponta Das Palmeirinhas. North of Luanda three profiles were carried out at Ponta da Moita Seca, at the northern boundery of Congo River Trench and at Cabinda. Three days stop was made in Luanda for change of Angolan scientists, and one day for change of cruiseleader. The survey ended on 28 May at Cabinda where Angolan scientist diembarked. The vessel steamed 7100 nm, and 187 trawlstations were worked.
