This book was released on 1985 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial surveys and acoustic recordings of bowhead whales and, secondarily, other marine mammals were made from mid-April through mid-May and from mid-July through October 1984 in the northern Bering, eastern Chukchi, and Alaskan Beaufort Seas. Survey results and observations of bowhead distribution, relative abundance, migration patterns, general behavior, and sound production for spring and fall seasons are presented. Presented here also are survey results and observations on gray whale distribution, relative abundance, and general behavior. Incidental sightings of all marine mammals are reported. (Author).

This book was released on 1987 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bowhead whale is a large, baleen whale found only in Arctic and sub-Artic waters. It is now one of the rarest cetaceans and is currently considered an endangered species. During August and September whales are present in areas of offshore oil exploration activity in the southeast Beaufort Sea. Aerial systematic and photogrammetric surveys were conducted in the southeast Beaufort Sea during August and September 1986, to investigate the distribution, relative abundance, and age segregation of the whales in relation to petroleum activites in the region. Two systematic surveys of the study area were completed from August 25-September 1 and September 7-14. Photogrammetric surveys of portions of the study area were conducted from August 25-September 1. Bowhead sightings recorded by researchers and by industry personnel during 1986 were also examined.

Available in PDF, EPUB and Kindle. Book excerpt: Presents results of aerial reconnaissance surveys of the white whale population of the Mackenzie River estuary from 1976 to 1985. Information is included on survey and data analysis methods, and on whale distribution and abundance (focusing on the 1985 survey), whale behaviour, and neonate sightings. Concludes with discussion on the timing and pattern of white whale movement and distribution, possible biases in survey technique, yearly trends in whale abundance, whale uses of the estuary, and effects of industrial activities on white whales.

This book was released on 1986 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the spatial distribution, relative abundance, and age segregation of bowhead whales in relation to petroleum industry activities and oceanographic features in the south-east Beaufort Sea during the 1985 open water season. Surface oceanographic conditions at the time of the aerial surveys (August-September) are described using satellite imagery analyses and in-situ temperature and wind data from industry vessels. Aerial photographic surveys provided information on the age/size class distribution and site tenacity of bowhead whales within the study area. Bowhead sightings recorded by other researchers working in that area during 1985 are also examined. Comparisons are made with results of previous bowhead whale surveys in the area.

Book excerpt: 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
