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: There are two objectives associated with this research project. The first is to establish vegetation and permafrost monitoring sites in the Inuvialuit Settlement Region (ISR) and the Gwich’in Settlement Area (GSA). The establishment of these permanent monitoring sites will improve our understanding of base-line environmental conditions in the region. The second goal for the 2011 monitoring season...

Licensed Year(s): 2011 2009 2007
Summary: The research project goal is to collect surface sediments, bank and levee sediments, particulate sediments and shallow sediment cores from lakes in the Mackenie River Delta, and to evaluate their utility as potential archives of information concerning past permafrost stability by assessing down-core changes in the age and supply of terrestrial carbon. In 2007 and 2009, teams led by Prof. Tim Eglin...

Principal Investigator: Gilbert, Graham L
Licensed Year(s): 2010
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...

Principal Investigator: O'Neill, Brendan H
Licensed Year(s): 2010
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...

Principal Investigator: Ensom, Timothy P
Licensed Year(s): 2010 2009
Summary: 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...

Principal Investigator: Pollard, Wayne H
Licensed Year(s): 2010 2009
Summary: This licence is being issued for the scientific research application no. 946. The objective of this research is to better understand the distribution of underground ice in hydrocarbon development areas. By identifying how much ice there is, the researcher wants to study how oil/gas activities and climate change could affect the land. Underground ice is one of the most unpredictable and problema...

Principal Investigator: Craven, Jim
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...

Principal Investigator: Nixon, Fredrick M.
Licensed Year(s): 2008
Summary: The objective of this project is to conduct snow surveys at selected sites in the Mackenzie Delta, related to permafrost studies. Snow surveys will be carried out at three selected sites in the Delta during early April. These are Circumpolar Active Layer Monitoring Program sites. There is a grid marked on these locations, where the researchers will be measuring the snow pack and snow density. M...

Principal Investigator: Morse, Peter D
Licensed Year(s): 2008 2007 2006
Summary: This licence was issued for the scientific research licence application number 748. The project objective is to determine how near-surface wedge ice volumes are related to geomorphic setting, which reflects soil physical properties, moisture contents, and process and duration of ice formation. Wedge ice geometry will be measured with a hand-held CRREL drill, permafrost cores extracted, and s...
