Summary: The goal of this thesis is to characterize the hydrology of an alpine valley's landscape Types (LTs) and how they affect storage and runoff responses to precipitation through the following four research objectives: 1) a physical description of LTs composing an alpine study catchment that are expected to exhibit distinct hydrological responses to precipitation inputs; 2) a physical description of w...

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Summary: 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 ...

Summary: The proposed field program is designed to provide information on fish habitat and wildlife in the area of three exploratory petroleum well sites and along their respective access routes in the Fort Liard/Nahanni Butte area. Researchers will travel to the well sites and along access routes sites by helicopter with survey work carried out by air, small boat and on foot. Fish habitat and water quali...

Summary: The proposed field program is designed to provide site-specific information on stream crossings, for planned improvements to the Mackenzie Valley winter road route. Researchers will travel to the crossing sites by helicopter from the closest community. At each crossing location, habitat assessments, water quality samples and fish census techniques (outlined in the DFO fisheries research permit) m...

Summary: The purpose of this study is to collect information about a variety of ecosystems contained by or in close proximity to the potential well sites for a proposed natural gas development. Fisheries and water quality studies will involve a survey of fish habitat, and of the water quality of any water bodies in the proposed development area. Any fish collection will be outlined by Department of Fisher...

Summary: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...

Summary: We propose to transport ad install new automatic weather stations by truck, fixed wing and helicopter to three sites in the Fort Simpson area between mid-June through mid July 1998. The automatic weather stations are both solar-powered and battery-powered, and collect and transmit meteorological data for use in weather forecasts and warnings. The weather stations will be used to support the scien...

Summary: This project continues to examine the history of plant communities in the Mackenzie River and Delta regions over the past 15,000 years. Using a hand auger, core samples of sediments are taken from lake bottoms and the sediments are analyzed for the presence of pollen and diatoms. Radiocarbon dating, a technique used to estimate age, will estimate when certain species were present in the past....

Summary: The research party will continue to study past climatic variation and will continue to examine the relationship between climatic change and vegetation response. They will continue lake sediment coring and will collect tree increment cores....
