Objectif(s): This project investigates the development of near-surface ice in sediments of the Mackenzie delta area. In permafrost terrain, an ice rich zone is frequently found just below the base of the active layer, and it is significant for several reasons: 1) It
Description du projet: This project investigates the the distribution and amount of near-surface ice in sediments of the Mackenzie delta area near Inuvik. Sites near Inuvik will be accessed via road and sampled using a hand held power auger. Soil cores will be removed and taken to the Inuvik Research Center for subsequent examination. The thickness of permafrost will be measured by near-surface water jet drilling which uses a pressurized stream of water to drill small holes in the frozen sediments. Environmental impacts of these procedures are negligible. During April the researcher fastened brackets to 6 - 10 spruce trees. The field work in July and August will include obtaining and analyzing permafrost cores and revisiting the spruce tree site prepared in April.
