The operation of a commercial shipping route through the Northwest Passage - a 1450 kilometre marine corridor linking Baffin Bay to the Beaufort Sea - has been a recurring dream of traders since the late fifteenth century. It is now fast becoming a practical possibility with the recent discoveries of hydrocarbon and other mineral resources. A consideration of the problems this will raise is urgently necessary. The Canadian Northern Waters Project, at Dalhousie University, Nova Scotia, has therefore initiated a four-year programme to investigate the feasibility of expanded arctic shipping and...

This book reviews the biology of bryophytes and lichens in the polar tundra, where these plants may form a dominant component of the vegetation. It considers adaptation to severe environments in terms of growth form, physiology and reproduction. The role of bryophytes and lichens is discussed in vegetation processes such as colonisation and succession, and in energy flow, nutrient cycling and other functional aspects of polar ecosystems, both natural and as modified by man, The range of microclimates experience by polar cryptograms is described using an energy budget approach, and the...

Arctic atmospheric pollution is now a major international issue. This volume presents the most authoritative review of this increasingly important subject for an audience of both scientists and administrators concerned with worldwide, as well as polar, pollution problems. Arctic Air Pollution is an edited collection of papers, first presented at a conference helo as the Scott Polar Research Institute in Cambridge in 1985. Building on foundations established at earlier meetings, this volume examines the problem of Arctic air pollution in an integrated, multidisciplinary fashion, with...

This is a translation of Vera Aleksandrova's classic book, first published in Russian, which characterizes the vegetation of this rather special botanical region. Much important botanical research concerned with Arctic ecology is carried out in the Soviet Union, but is seldom available in English. Dr Aleksandrova's book is based on her own extensive research in the northern areas of the Soviet Arctic. Dividing the high Arctic into areas based on the characteristics of their vegetation, the book presents a probing analysis of the ecology of such regions worldwide. After describing the general...

The crossing of the Northwest Passage in August 1985 by a US icebreaker, without requesting authorisation, raised the whole question of Canada's sovereignty over the waters of its Arctic Archipelago. Given this controversy and the existence of similar situations in other parts of the world, this book presents an examination of the international legal validity of Canada's claim by an in-depth study of three possible bases in international law: the sector theory, the doctrine of historic waters and the Straight baseline system. This work is the second of a series of monographs arising from the...

The system of international co-operation in the Antarctic has been evolving rapidly since the signing of the Antarctic Treaty in 1959. Inextricably linked to this co-operation is the question of the rational management of Antarctic resources. In this book Professor Orrego Vicuna examines in depth the legal framework the Antarctic Treaty, sovereignty, jurisdiction and the law of the sea as it relates to the exploitation of Antarctic minerals. This is fast becoming a live issue with the ever-growing potential for the development of these resources. The first part of the book examines the main...

The Antarctic Treaty regime is a uniquely successful legal system which preserves Antarctica for peaceful purposes and guarantees freedom of scientific research. This volume based on an international conference, examines the legal, political and environmental issues that it raises. After setting the scene of the Antarctic environment, the early chapters discuss the legal issues involved in the Treaty. Later chapters consider protection of the marine environment and the regulation of mineral exploitation. The book concludes with a discussion of Antarctica and its development.
