Book Description

This paper presents results of geological mapping conducted in 2003 as part of a project addressing the stratigraphic, structural, and metamorphic relationships along the Columbia River valley in British Columbia. The results relate to the stratigraphy of the Upper Arrow Lake & Trout Lake areas and the structural geology of the Columbia River fault zone. The significance of the stratigraphic succession found along Upper Arrow Lake is discussed in regard to previous theories concerning a crustal-scale displacement along the fault zone.

Book Description

This report details the results of geochronological measurements made on 19 samples from locations in & directly adjacent to the eastern Bella Coola map area of British Columbia. The analytical data were extracted from a large, mostly unpublished data set that includes uranium/lead, potassium/argon, and argon/argon geochronometry for other parts of the Anahim Lake and Mount Waddington map areas. Analytical data, geological ages, and relevant observations for each dated sample are presented in chronological order. The age results provide broad constraints on pluton emplacement, volcanic eruption, and structural & metamorphic relationships in the study area, although these are discussed only in general terms.

Book Description

This study was conducted in response to concerns raised by local residents about water quality in Fisherman Lake, located 18 kilometres north-west of Fort Liard, Northwest Territories. Field investigation of the lake revealed the existence of 13 gas seeps (largely methane) with distinct bubble trains rising continuously to the surface. This paper presents results of analyses of the gas & of the lake water and the determination, through isotope analyses, of whether the gas is of biogenic origin (related to the decomposition of organic matter) or thermogenic origin (representing a seep from geological strata of the gas field below the lake). The possible effects of methane on the lake water are also discussed and recommendations are made for further research.

Book Description

This fascinating book is the first comprehensive analysis of the economic, social and political interrelationships between tourism and global environmental change: one of the most significant issues facing humankind today. Its contributors argue that the impacts of these changes are potentially extremely serious both for the tourism industry, and for the communities dependent upon it. Integrating knowledge from the social and physical sciences, this significant book explores they key issues surrounding global environmental change, as well as government and industry willingness to meet the challenges posed by it. Divided into four main sections, it investigates: the tourism and global environmental change relationship in specific environments global issues related to environmental change differing perceptions of global environmental change held by tourists and the tourist industry. Comprehensive in scope, topical and integrative, this key text is essential reading for students, scholars and researchers in all aspects of tourism, geography and environmental studies.
