20. ABSTRACT (Continue on reverse side II necessary and Identlly by block number) 





The effects of noise from offshore oil and gas operations on marine mammals were assessed by a multi- 





faceted study. The hterature was surveyed for available data on noise from oil platforms and on hearing capa- 





bilities of marine mammals. Data on animal behavior around the platforms v/ere collected by field observations 





and interviews. The noise from platforms was measured at various geographical locations and analyzed in the 





laboratory. Evaluation of the combined data indicates that certain platforms are relatively quiet, and therefore 





platforms with minimal sound emission can be designed. The highest level components of the noise from oil plat-
