The Mackenzie Delta, Northwest Territories, has an area of some 13,000 kmē and is the second largest delta in North America. It receives the discharge from a watershed of about 1,900,000 kmē in extent, comprising 11 major drainage basins. The report presents a quantitative synthesis of the ecosystems of the Mackenzie Delta. The objective of the synthesis is to examine the structure and relative sensitivity of ecosystem components and processes within the Mackenzie Delta, and to identify significant information gaps. Most of the information in the synthesis is drawn from studies undertaken by B.C. Hydro from 1980 through 1983. A total of 36 B.C. Hydro source reports, 33 of which deal with the Mackenzie Delta, 2 with the Beaufort Sea and 1 with socio-economic concerns, are listed in an appendix. A keyword index provides a listing of all physical and biological data contained in the source reports. Supplementary information has been taken
from other recent studies and from the literature. ...

Given the importance of the Mackenzie Delta, it was appropriate to bring together scientists and managers to discuss past research efforts, the current state of our knowledge, and future research directions. The primary aim was to attract scientists from various disciplines to discuss interactions between different elements of the physical and biological environments. These proceedings are the formal record of the workshop held at the National Hydrology Research Centre in October 1989. The published papers are not a comprehensive review of past research, but are a snapshop of current investigations in the area, brief discussions of future research requirements, and a source of references for those with an interest in the Mackenzie Delta. Besides the formal papers, there was much discussion during the workshop on research needs; on which some workshop participants later elaborated. The following sections are neither a comprehensive
summary of the discussions at the workshop nor those following it. Rather, they are personal impressions of past research directions and current needs, flavoured by discussions at the workshop and information subsequently received.

If the CO2 content of the atmosphere continues to rise and the predicted response of climate to this increase is correct, then the Mackenzie valley will experience one of the highest rises in mean annual air temperature for any region in Canada. This possibility calls into question the response of pemafrost and the behaviour of ice-rich sediments which typify this region. Although ice-rich permafrost inherently resists climate warming, the potential for thawing to disrupt communities and industrial and economic activity warrants an evaluation of terrain sensitivity so that the consequences of climate warming in the Mackenzie valley can be anticipated. This report is divided into five sections that provide a basis for understanding how climate change will physically affect the Mackenzie valley. ... [These sections, consisting of 20 papers, include the following: Physical setting of the Mackenzie valley, Indicators of past climate,
Permafrost and ground temperature, Landscape processes, and Effects of climate change on permafrost.]
Beaufort Sea Conference 2000 : renewable resources for our children, Sept. 15-18 , Inuvik, NT

The Beaufort Sea Conference 2000, held in Inuvik, Northwest Territories, in September 1999, had three objectives: to review our current understanding of the renewable aquatic resources of the Beaufort Sea; to review the factors that affect those resources; and to develop a vision that will guide management of those resources for the benefit of present and future generations. To achieve these objectives, the conference brought together representatives of the full range of groups interested in the renewable resources of the Beaufort Sea. These included hunters and fishers, other resource users, scientists, government managers, educators, students, and the public. The conference was structured to encourage interaction between participants so that they could jointly discuss opportunities for the future. ... This special issue of the journal "Arctic" presents the formal scientific papers on each resource species or group and the presentation
by Inuvialuit elder Billy Day. The paragraphs below summarize the conference discussions under the four themes, as well as the discussions of the youth delegation. The Canadian Beaufort Sea region pioneered and put into practice the theory of co-management in the Canadian Arctic, beginning with the signing of the Inuvialuit Final Agreement in 1984 and the Gwich'in Final Agreement eight years later. Workshop discussions considering the role of co-management of renewable resources in this region focused on the following challenges for the future: Community engagement .... Youth and elders .... Communication .... Good governance .... Research .... Traditional ecological knowledge .... Chaos and innovation ....
