Summary: “Environmental Studies across Treeline (ESAT) in the Mackenzie Delta region” is a northern based collaborative program with an objective to enhance the understanding of environmental conditions in the Mackenzie Delta region through scientific studies and monitoring. Specific studies include: 1) monitoring permafrost conditions in the Mackenzie Delta region; 2) examining freeze-back of the active l...

Summary: The objective of this research is to understand how climate change is affecting permafrost in the western Arctic, particularly in the outer Mackenzie delta. The research team also intends to investigate the ice content of the ground and how this may affect terrain stability. The research team wishes to study changes in ground temperature at various locations in the western Arctic, ranging from Her...

Summary: The objectives of this project are to define the impact of snow depth, surface vegetation, and soil characteristics on spatial and temporal variations in active-layer freeze-back in the low arctic tundra east of the Mackenzie Delta. The duration of freeze back will be determined from the ground temperatures measured at the top of permafrost. This temperature only declines at the site when the ac...

Summary: The first objective is to compare present ground ice conditions to those recorded thirty years ago, and from this, obtain an estimate of the rate of ground ice accumulation over the past three decades. This is possible as the exact locations cored in 1979 and 1980 are marked, and new cores can be taken adjacent to these. The second objective is to compare ice conditions from sites within the basin...

Licensed Year(s): 2009
Summary: This licence is being issued for the scientific research application no. 956. The primary objective of this study is to field test and assess the utility of an electromagnetic (EM) geophysical technique called magnetotellurics (MT), as an inexpensive method for mapping spatial variations and changes within permafrost in the Mackenzie Delta area. Due to the large change in soil electrical resist...

Summary: The main objective of the proposed research is to establish the origin of massive bodies of underground ice at two key massive-ice localities in the Mackenzie Delta area: i) Cliff Point, Liverpool Bay and (ii) near Eskimo Lakes. The research will be carried out by an interdisciplinary team of scientists examining the geology, glaciology and chemistry of the ice and adjacent sediments. The research...
