Book Description
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 Description
"From the pressures of development, technological advances, globalization and climate change to social and cultural life, this book attempts to define the nature of competing demands and assess their impact on the environment. These essays provide a detailed examination of ocean and coastal management in the Canadian north, exploring a wide range of issues critical to environmental stewardship, and breaking the ice to connect academics, government managers, policy-makers, aboriginal groups and industry." --Book Jacket.
