Summary: The objectives are to measure a suite of trace elements and isotopes (TEIs) in the active layer and permanently frozen layer of permafrost cores sampled near the Mackenzie River, and to compare these concentrations to those observed in submarine groundwater discharge and Mackenzie River discharge in order to determine whether permafrost-associated TEIs are being transported to the coastal Arctic. ...

Summary: Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...

Summary: The research objective is to sample the active layer of the permafrost in areas where patterned ground and thermokarst are present. The data gained will help the researchers to understand possible cold-climate processes in the northern hemisphere of Mars. The researchers will be based in Inuvik and Tuktoyaktuk. They intend to visit areas in the vicinity of Inuvik and Tuktoyaktuk where patterned...

Summary: Oil and gas extraction in permafrost areas causes vertical surface displacements that have in the past caused serious environmental issues, such as massive subsidence and land slides. Methods of monitoring such vertical subsidence are accurate, but rely...

Summary: This study investigates the physical and chemical characteristics of permafrost in the Mackenzie Delta region. The thawing of ice-rich permafrost can result in subsidence or terrain instability. Determination of thaw-sensitive terrain is required to pla...

Summary: The primary objective of this project is to develop improved understanding of the fluxes of water and energy in northern regions, and to develop improved computer models of these processes. The Trail Valley Creek site will be accessed by helicopter and s...

Summary: The research team will obtain sediment cores from a series of lakes near Reindeer Station and Inuvik for the purpose of reconstructing the hydrological, climatological and geomorphic history of the lower Mackenzie River basin. The research will require fieldwork between 15 April and 25 April. Research will involve the development of a high-resolution paleoenvironmental record based on lake sedime...

Summary: This season, a party of two will survey tubes between Tsiigehtchic and the coast during March and April and from Fort Simpson to the Arctic Coast in July and August. Staff of the Inuvik Research Centre may take late season measurements north and south of Inuvik as part of a cooperative program. Travel will be by road, small boat on the river and helicopter from Inuvik. Access to the sites is alw...

Summary: 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 ...

Summary: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...
