Winter Flow Regime and Icing Dynamics of Tundra Streams near the Inuvik to Tuktoyaktuk Highway
chercheur principal: Ensom, Timothy P
Année(s) de permis: 2022 2021 2020 2019 2018 2017
Résumé: The objectives of the project are to: 1) determine the spatial extent, distribution, and timing of winter icing events in streams along the Inuvik to Tuktoyaktuk Highway (ITH) through groundbased and aerial reconnaissance of stream crossings; 2) identify relations between physical watershed characteristics and icing dynamics through field observations and analyses of watercourse and catchment mo...

Influence of Mackenzie Delta Channel Thermal Regime on Permafrost
chercheur principal: Ensom, Timothy P
Année(s) de permis: 2010 2009
Résumé: The purpose of this research is to measure the seasonal temperatures of streambeds at several sites in the Mackenzie delta and adjacent tundra uplands, and predict the implications of these temperature patterns for local permafrost conditions. This project will seek to determine whether channel size and depth affect the annual thermal regime of the streambed, and will also use collected temperatu...
