South African marine pollution survey report 1976-1979

Abstract

This report contains information gained during the period January 1976 to March 1979, and follows on the previous report of Cloete and Oliff . Impact areas covered by this report include East London and Algoa Bay, the Mossel Bay area, several points on the Cape Peninsula and Saldanha Bay. Estuaries visited included Kosi Bay, St Lucia, Richards Bay, Durban Bay, and the Umgababa, Umzimvubu, Mngazana, Bashee, Buffalo and Swartkops estuaries. Further south, Knysna and the Storms, Groot, Keurbooms and Bietou Rivers were studied, as well as the Wilderness Lakes. In addition information from the Berg, Olifants and Orange Rivers on the West Coast is included. Results from sampling undertaken along oceanic transects on the East Coast, the South Coast, and the West Coast are presented. Several general studies are also described, including oil spills resulting from the Goel 1 stranding on Robben Island, and the Venpet-Venoii collision, and a survey of chlorinated hydrocarbons in marine fauna of South Africa.
