Species at risk criteria and seismic-survey noise thresholds for cetaceans [electronic resource] / James A. Theriault, Hilary B. Moors-Murphy. Critères des espèces en péril et seuils des niveaux de bruit des levés sismiques pour les cétacés Ottawa : Fisheries and Oceans Canada, 2015. v, 42 p. : fig., graphs, tables.

Mitigation measures are required for seismic survey operations occurring in Canadian waters to reduce potential negative effects on marine mammals. Since 2008, the statement of Canadian practice with respect to the mitigation of seismic sound in the marine environment (SOCP) has been used to guide the minimum standard mitigation measures recommended for seismic operations in Canadian waters. As an understanding of anthropogenic impacts and Canadian legislation evolves, it is necessary to revisit the policies and protocols intended to minimize such impacts. This research document strives to address if quantitative acoustic thresholds can be recommended to meet the needs of listed cetacean species protected by the Species at Risk Act (SARA). Where quantitative acoustic thresholds are not available, qualitative thresholds are discussed. gccst Whales gccst Gas industry gccst Petroleum industry gccst Fisheries management Canada.
