Enhancement of Permafrost Monitoring Network and collection of baseline terrain information in Mackenzie Valley Corridor - Deh Cho Region
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2006
Summary: The Geological Survey of Canada maintains a network of active layer and permafrost temperature monitoring sites in the Mackenzie region in order to document the response of permafrost conditions to climate change. Gaps exist in the network in the permafrost zones north of Norman Wells, the Mackenzie Delta region, and on shorelines and coastlines. Enhancement of the network is essential to provide ...


Surficial Materials Investigations, South Nahanni Area
Principal Investigator: Menounos, Brian p
Licensed Year(s): 2006
Summary: The various objectives of the study are: to refine the previously compiled landslide inventory map with field checking, to identify causal mechanisms to slope instability (such as bedrock or surficial material type, aspect, elevation, glacial history, and permafrost distribution), to identify frequency of landslide types, to examine landscape patterns in the Nahanni karst area to establish relatio...


Soil Climates of the Mackenzie Valley
Principal Investigator: Tarnocai, Charles
Licensed Year(s): 1994
Summary: Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...


Distribution and Genesis of Karst Landforms in the Northern Mackenzie Mountains, N.W.T.
Principal Investigator: Hamilton, James P.
Licensed Year(s): 1991
Summary: Karst landscapes are landforms developed on carbonate rocks in humid and temperate climates and are relatively rare in permafrost areas. The Researcher and team will focus on understanding how Karst has and is developing in the Northern Mackenzie Mountains. This will be done by identifying karst forms and examining how water moves in these environments....


Quaternary Geology, South Shore of Great Slave Lake
Principal Investigator: Lemmen, Donald
Licensed Year(s): 1991 1990
Summary: The Researchers will collect small samples of surficial materials for sedimentological, geochemical and paleoecological analysis. They will map, describe and explain the unconsolidated deposits, landforms, permafrost and organic cover and study patterns of glacial dispersal and drift geochemistry....


Reconstruction of Holocene Environments
Principal Investigator: Begin, Christian
Licensed Year(s): 1990
Summary: The research team will investigate a few localities to determine the best sites to study eolian deposits (sand dunes) and features related to permafrost degradation. Samples of granular and organic deposits will be taken....


Isotope Hydrology and Geochemistry Studies, Manners Creek Basin, N.W.T.
Principal Investigator: Edwards, Thomas W.D.
Licensed Year(s): 1990
Summary: The Researcher and his assistant will collect samples of snow, rain, stream water, pond water and ground water from undisturbed sites in the Manners Creek Basin. Measurements of naturally occurring chemicals and isotopes in surface and subsurface waters will be used to study the movement and mixing of waters in a boreal watershed in the zone of continuous permafrost....
