The 2013 survey area was expanded to achieve complete coverage of the summer range of EC-WG bowhead whales, because it overlaps to a great extent with summer distributions of Baffin Bay narwhals and because the survey methodology is similar for both species. [...] The partial abundance estimate obtained from the 2002 survey was imprecise due to the small number of whales observed and the large uncertainty associated with the estimate. [...] As the ice breaks up, bowhead whales found in northern Foxe Basin in spring likely move through Fury and Hecla Strait to summer in the Gulf of Boothia and Prince 2 Central and Arctic Region Updated abundance and harvest advice for EC-EG bowhead Regent Inlet. [...] The current level of total allowable harvest is five bowhead whales per year in the NSA, and two bowhead whales per year in the NMR. [...] ANALYSIS Aerial Survey Design and Analysis The High Arctic Cetacean Survey (HACS) was designed to cover the largest possible proportion of the population's summering range and improve on the precision of past surveys.

The Bowhead Whale: Balaena mysticetus: Biology and Human Interactions covers bowhead biology from their anatomy and behavior, to conservation, distribution, ecology and evolution. The book also discusses the biological and physical aspects of the Arctic ecosystem in which these whales live, with careful attention paid to the dramatic changes taking place. A special section of the book describes the interactions of humans with bowheads in past and present, focusing on their importance to Indigenous communities and the challenges regarding entanglement in fishing gear, industrial noise and ship strikes. This volume brings together the knowledge of bowheads in one place for easy reference for scientists that study the species, marine mammal biologists, but, equally important, for everyone who is interested in the Arctic. Presents the only current book dedicated to this species Includes short, high-impact chapters that make it possible to review all bowhead biology in one compact volume Illustrated with never-before published photos of bowheads in their natural environment Provides a platform for an in-depth understanding of indigenous whaling

European Whales, Dolphins, and Porpoises: Marine Mammal Conservation in Practice presents an intimate view of the workings of international conservation agreements to protect marine mammals, detailing achievements over the last 25 years, identifying weaknesses and making recommendations that governments, scientists, marine stakeholders and the public can take to improve conservation efforts. The book is written by an experienced marine mammal scientist and award-winning conservationist, providing a unique synthesis on their status, distribution and ecology. In addition, it presents information on various conservation threats, including fisheries by catch, contaminants, noise disturbance, plastic ingestion and climate change. This comprehensive resource will appeal to marine mammal conservationists and researchers, as well as environmental and wildlife practitioners at all levels. Offers an accessible review on how scientists study this challenging group of mammals to gather necessary evidence for conservation action Illustrates, with striking images, all recorded regional species, including distribution maps, key threats and specific research methods Includes contributions from leading scientists, conservationists, and members of government and international bodies, like IWC and UNEP
