Résumé: The objectives of the Alaska-Canada Barren Lands Traverse is to: learn about changes in the Arctic from historical observations, to observe commercial and infrastructure changes in relation to how they compare and contrast to the impacts of a warming Arctic climate, and to compile baseline measurements of snow cover physical properties for validation of satellite datasets and snow cover chemical p...

Résumé: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Résumé: The main objectives of the field reconnaissance at landslide sites are as follows: o To visit landslide sites that exhibit on-going movement in order to qualify the rate of movement; o To identify main failure mechanisms and factors that contributed to slope failures; o To validate previous data collected through airphoto interpretation and remote sensing techniques; o To collect soil samples ...

Année(s) de permis: 2006 2005
Résumé: The purpose of this project is to learn about the types of environmental changes Holman has faced in the past and how these changes have affected community infrastructure. The researcher seeks to describe community infrastructure and how it might be affected by environmental change. The researcher will identify who, or which agencies, will be expected to respond to risks affecting infrastructure a...

Résumé: The long term goal of this research is to develop a biogeochemical model for lakes in the Mackenzie Delta and a model for assessing the effects of stresses on rivers resulting from global change. This is year 13 of a 20 year program. Specific goals for this field season include: 1) investigating the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta; 2)...

chercheur principal: Salokangas, Raila M
Année(s) de permis: 2005
Résumé: The objectives of this study are 1) to gather and analyze views and opinions of the Mackenzie Gas Project (MGP) and its possible impacts on the culture, socio-economics and environment from Gwich’in beneficiaries living in Aklavik, Inuvik, Fort McPherson and Tsiigehtchic, and 2) to distribute this information back to communities. The field work will be conducted by Raila Salokangas (the resear...

Année(s) de permis: 2005 2004
Résumé: The purpose of the study is to better understand how climate and environmental changes affect river water chemistry and material export fluxes, and in turn, how biogeochemical tracers can be used to examine the impacts and biogeochemical consequences of environmental changes. This is the second year of a three-year study. The researchers plan to sample the Mackenzie River starting in late Apri...

Année(s) de permis: 2004 2003
Résumé: This project involves working with the Gwich'in Renewable Resources Board, the Tetlit Gwich'in Renewable Resources Committee and elders/harvesters from Fort McPherson to document traditional indicators and methods for community-based monitoring. The main focus of the project in on berries and berry-harvesting. Specific goals include: identifying signs and symbols traditionally used by the Gwich'in...

chercheur principal: Kruse, Jack
Année(s) de permis: 1999
Résumé: Part A: "Possible Futures Model". Researchers have constructed models which project how force of change will affect communities in the future, based on local knowledge and research findings of previous studies. In 1998-99, the "Possible Futures Model" will be presented to people of Fort McPherson and Aklavik. The model allows users to consider the effects of changes that may occur in the next 40 ...

Résumé: The objective of this work is to make physical measurements of the size, shape and distribution of earth hummocks in areas where the 1968 forest fire did not occur. We are developing a mathematical model which predicts hummock size and activity based on soil properties and environmental conditions. Because hummock activity appears to be very sensitive to environmental changes, our model, coupled ...
