Assesses the conservation status of a population of bottlenose whale, Hyperoodon ampullatus, that resides year round at the entrance of a prominent submarine canyon on the edge of the Scotian Shelf east of Sable Island. Information is included on the whale's geographic distribution, population size and trends, protection status, habitat, factors limiting the whale population size and distribution, and the special significance of the species for Canada. Concludes with discussion of the current consensus regarding the status of the species and a proposed designation of the species as vulnerable, with the rationale for such a status.

Passive acoustic monitoring is increasingly used by the scientific community to study, survey and census marine mammals, especially cetaceans, many of which are easier to hear than to see. PAM is also used to support efforts to mitigate potential negative effects of human activities such as ship traffic, military and civilian sonar and offshore exploration. Walter Zimmer provides an integrated approach to PAM, combining physical principles, discussion of technical tools and application-oriented concepts of operations. Additionally, relevant information and tools necessary to assess existing and future PAM systems are presented, with Matlab code used to generate figures and results so readers can reproduce data and modify code to analyse the impact of changes. This allows the principles to be studied whilst discovering potential difficulties and side effects. Aimed at graduate students and researchers, the book provides all information and tools necessary to gain a comprehensive understanding of this interdisciplinary subject.

In the context of species at risk conservation, recovery is the process by which the decline of an endangered, threatened or extirpated species is arrested or reversed, and threats are removed or reduced to improve the likelihood of the species' persistence in the wild. [...] In the spirit of the National Accord for the Protection of Species at Risk, the Minister of Fisheries and Oceans invites all responsible jurisdictions and Canadians to join Fisheries and Oceans Canada in supporting and implementing this strategy for the benefit of the northern bottlenose whale and Canadian society as a whole. [...] There are several historic centres of abundance based on whaling information: west of Spitsbergen, around Iceland, off northern and western Norway, in Canadian waters of the Davis Strait, and along the edge of the eastern Scotian Shelf, the southern-most centre of abundance. [...] There are several known areas of abundance for the species, two of which are off Canada: the edge of the eastern Scotian Shelf and the Davis Strait. [...] This recovery strategy is intended to serve as a blueprint for the recovery of the Scotian Shelf population of the northern bottlenose whale by summarizing the best available information on the biology and status of the population, and by identifying objectives and strategies for its recovery.
