Summary: This research will investigate: A) the physical and chemical characteristics of permafrost in the Mackenzie Delta region to identify areas of ice-rich permafrost or thaw sensitive terrain. Second; B) the effect of permafrost degradation on water quality...

Summary: In the Mackenzie Delta region, many of the drilling mud sumps constructed in the 1970s have partially or completely collapsed. The collapse of a sump can release contaminants previously immobilized in permafrost. The long-term degradation of many sumps...

Licensed Year(s): 2001 2000
Summary: This study will attempt to understand and predict how cold the ground surface gets in the winter under snow. Transportation to the site will be by helicopter and accommodation at the site will be in tents or at an existing cabin. Travel from camps to sample sites will be by foot. Electronic data recorders were installed in August 2000 to record air, ground and surface temperature through the wi...

Principal Investigator: CLARK, Ian D.
Licensed Year(s): 2000 1999
Summary: The objective of this project is to observe and collect rock specimens from limestone outcrop sites. These samples will be used to interpret groundwater flow systems that occurred in the Arctic in the past when the climate was much warmer. Several sites will be visited for the purpose of examining and collecting rock specimens along the Dempster highway south of Inuvik. Two day trips west of Akla...

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: Dyke, Larry
Licensed Year(s): 1998 1997
Summary: Field work this year will be devoted to 1) determining the maximum extent of potassium chloride migration from sumps examined in 1997, 2) examine the Mallik L-38 sump constructed in 1972 as one of the oldest sumps in the Delta, 3) examine the sumps in Parsons Lake area where topographic relief has added the potential for salt migration due to groundwater flow. Sumps along Kumak Channel, near the m...

Principal Investigator: French, Hugh
Licensed Year(s): 1997
Summary: The researcher will be studying the cryostructures which occur in perennially frozen, unconsolidated ice rich sediments. This builds upon earlier work in the Sachs Harbour and Sachs River Lowlands undertaken in the period 1970-1985. Will use boat transportation across the Sachs Harbour Bay and possibly towards Cape Kellett. The 1997 work will be a reconnaissance visit. This work will be continue...

Principal Investigator: Mackay, Ross J.
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991 1989
Summary: Transportation to and from the field sites will be by helicopter, either from Tuktoyaktuk or Inuvik, to and from Garry Island and Illisarvik (West Point, Richards Island). Most of the equipment used in the field is for measurement purposes , such as surveying equipment for precise height, distance, and tilt determinations of bench marks already installed across ice wedges and elsewhere, temperatu...

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 thousands years, in order to determine what might happen in the future....

Principal Investigator: Wein, Ross
Licensed Year(s): 1994
Summary: Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...
