2005 synopsis on Canadian environmental legislation and policies affecting active sonar research based in Nova Scotia

Defence Research and Development Canada (DRDC) Atlantic has a number of sonar projects that require the underwater transmission of acoustic energy. Because of potential adverse environmental effects, a number of international and Canadian laws as well as Department of National Defence (DND) policies impact on these research activities. Of particular interest for this paper are the Canadian legislation and departmental policies relating to the potential impact of active sonar research sea-tests on marine mammals.
