Summary: This licence has been issued for the scientific research application No. 5791. The objectives of this study are to (1) evaluate the geologic setting including geochemistry, and dating of sediments to establish a regional history of the area. (2) investigate the geologic setting of multiple buried, massive ice bodies. And (3) develop a geologic and hazards map along the ITH, highlighting feature...

Summary: The goal is to reconstruct long-term environmental change (hundreds to thousands of years) by examining chemical and biological fossil remains preserved in lake sediment cores, in order to better understand how thawing permafrost impacts lake ecosystems. 1) Water chemistry and plankton survey The research team will collect lake water samples from the study lakes to analyze for water chemistry...

Principal Investigator: English, Michael C
Licensed Year(s): 2014
Summary: The objectives of this research project are: 1. to extract sediment cores from three different regions of the Northwest Territories namely: the low arctic tundra (continuous permafrost-Daring Lake), Taiga Shield northern boreal (widespread discontinuous permafrost-Wekweeti), and Taiga Shield boreal (sporadic discontinuous permafrost-Baker Creek Watershed) which provide the research team with a re...

Summary: The objectives of this research project are to provide a better understanding of the permafrost under a proposed road right-of-way (ROW) and to delineate potential aggregate deposits. This will include mapping: permafrost distribution, massive ice bodies (including wedge ice), depth to massive ice, lower contacts of massive ice, zones of thermokarst, ice rich sediments (thaw sensitive), active lay...

Summary: Sand, gravel and crushed stone are valuable geological resources, collectively known as aggregates. They are essential bed, foundation and building materials. The presence of massive ice in aggregate deposits results in a series of resource management problems, particularly for the oil industry and its contractors who rely on local granular deposits as building material. From an environmental pers...

Principal Investigator: Murton, Julian B
Licensed Year(s): 1999 1998
Summary: The main objective of the proposed research is to establish the origin of massive bodies of underground ice at three key massive-ice localities in the Mackenzie Delta area: i) Mason Bay area, NE Richards Island; (ii) the central Eskimo Lakes region and (iii) the Liverpool Bay area. The research will be carried out by an interdisciplinary team of scientists examining the geology, glaciology and c...

Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The purpose is to collect samples of ground ice and to measure air, ground and lake temperatures. We use the information to help understand how the permafrost in the area has changed in the last few thousand years, in order to determine what might happen in the future....

Principal Investigator: Dyke, Larry
Licensed Year(s): 1993
Summary: In this ongoing study, the frequency and characteristics of landslides occurring in the Mackenzie Valley area are examined. I am trying to determine the roles that forest fires, climate changes and water flow in rivers play in the location and number of landslides. The field work will involve taking measurements on past landslides that include measuring permafrost features and taking core samples...

Principal Investigator: Dyke, Larry
Licensed Year(s): 1992 1991 1990
Summary: The research will involve permafrost adjustment studies on the outer Delta as well as preliminary work on landslide mechanisms along the Mackenzie River between Norman Wells and the head of the Mackenzie Delta. The purpose of the work is to understand the importance of sedimentary processes in controlling the growth and disappearance of permafrost along the coast of the Beaufort Sea....

Licensed Year(s): 1994 1993 1993 1992 1992 1991
Summary: A transect consisting of geotechnical boreholes and detailed geophysical studies will document the geological, geothermal and geotechnical conditions of perennially frozen sediments at three sites on Richards Island in the Mackenzie Delta....
