Book excerpt: "The overall objective of this study was to investigate the relationships between the distribution of bowhead whales in the Beaufort and Chukchi Seas and oceanographic features visible in satellite images. Particular attention was to be paid to the Pt. Barrow area ... we first examined the timing of the fall migration for the years 1979 to 1986, and compared it to variations in environmental conditions in those years. ... We also investigated local environmental conditions at Barrow, to determine if the feeding in that area might relate to some observable oceanographic phenomena. ... we also studied the relationship between the end of the peak migration past Prudhoe Bay and a number of environmental variables. ... A brief analysis of the very large annual variations in the timing and geographic nature of break-up and the duration and extent of open water was also conducted ... --Summary.

This book was released on 1986 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial surveys of the summertime distribution of bowhead whales in the southeastern Beaufort Sea have shown that the distribution of bowheads has been quite variable over the four years of study, 1980-83. This report presents the results of an investigation of the relationship between the observed distribution of bowhead whales in the Canadian Beaufort Sea and the physical and meteorological patterns that might affect the distribution of zooplankton in the Beaufort Sea. The overall aim of this study was to identify easily-monitored parameters that could be used to predict bowhead whale distribution.

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

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.

Download or read book The Alaskan Beaufort Sea written by Peter W. Barnes and published by Elsevier. This book was released on 2013-09-17 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaskan Beaufort Sea: Ecosystems and Environments provides an interdisciplinary view into almost all aspects of the environment, with a detailed survey of the background literature. This book focuses on the Alaskan Beaufort Shelf environment. Organized into four parts encompassing 20 chapters, this book begins with an overview of the characteristics and history of the region in which the research took place and defines the objectives of the studies program. This text then examines the subsynoptic meteorological networks along the Beaufort Sea coast and shelf. Other chapters consider the thermally generated mesoscale effects on surface winds and the orographic mesoscale effects on surface winds. This book discusses as well the phytoplankton associations and relative phytoplankton production in the area between the 20-m depth contour and the edge of the ice in summer. The final chapter deals with the characteristics of the ice cover and oil-ice interactions that will affect cleanup activities after blowout. This book is a valuable resource for scientists and conservationists.

McLaren and published by Ottawa, Ont. : Environmental Studies Revolving Funds. This book was released on 1985 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systematic aerial surveys were conducted in the southeast Beaufort Sea on 19-24 August and 6-11 September 1983 to document the numbers and distributions of bowhead whales and of other marine mammals. The study area extended from 141 W (Alaska-Yukon border) eastward to 128 40 W (near Cape Bathurst), and from the 2 m depth contour northward to about 25 km north of the 100 m depth contour, except between 141 W and 138 W where the northern boundary was at 70 20 N. The northernmost 25 km sections east of 138 W also extended beyond the 200 m depth contour, and thus included the steep shelf break beyond the shallow continental shelf.

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: The Pacific Arctic region is experiencing rapid sea ice retreat, seawater warming, ocean acidification and biological response. Physical and biogeochemical modeling indicates the potential for step-function changes to the overall marine ecosystem. This synthesis book was coordinated within the Pacific Arctic Group, a network of international partners working in the Pacific Arctic. Chapter topics range from atmospheric and physical sciences to chemical processing and biological response to changing environmental conditions. Physical and biogeochemical modeling results highlight the need for data collection and interdisciplinary modeling activities to track and forecast the changing ecosystem of the Pacific Arctic with climate change.
