ABSTRACT
On the 18th January 2000 a broken pipeline owned and operated by the oil company Petrobras spilt some 1300 tonne of bunker fuel into Guanabara Bay, Rio de Janeiro. The wildlife response was divided amongst 2 operational strategies and included – avian fauna and cetaceans. This paper deals with the cetacean response only. Cetaceans are generally not considered as an important feature of an oil spill response. Contingency planning for cetaceans in oil spills is now becoming an important element for preparedness for some countries. The cetacean response in Guanabara Bay specifically targeted a pod of about 70 members of the species Sotalia fluviatilis, a small dolphin that inhabits the bay. The response included the development of a plan that included a response system, a monitoring program and action plans. The response system detailed the mechanism for the plan to work and adopted the incident control management system. The monitoring program related to the study of any short term or long term deleterious effects resulting from the spill and consisted of basic spatial, temporal and behavioural studies. Action plans were developed specific to the character of Guanabara Bay and included the rescue and rehabilitation strategies necessary to respond to oil affected cetaceans. A training program was then developed and implemented to personnel who were to enact the cetacean response.
