The possible environmental impacts of petroleum exploration activities in the southern Gulf and Sydney Bight ecosystems
By P.R. Boudreau, G.C. Harding, K. Lee and P.D. Keizer
Abstract
There has been offshore oil and gas exploration activity on Canada's East Coast since the early 1970's. During that period considerable knowledge has been acquired about the potential impacts of these operations. In addition knowledge has also been acquired for more advanced offshore oil and gas industries in the Gulf of Mexico and the North Sea. This document provides a brief overview of the types of potential impacts. In the absence of a specific exploration proposal it is not possible to be more specific about potential impacts and the severity of risks. Any proposed activity must submit an environmental assessment that provides a detailed evaluation of potential impacts, identification of proposed mitigation, and assessment of the risk associated with any residual impacts.
The three lease areas under consideration are located in coastal waters of Nova Scotia. Previous exploration activity has occurred farther offshore. The physical and biological characteristics of the coastal environment are significantly different from the offshore and will require special consideration in environmental assessments.
