Arctic Peatland Carbon and Holocene Warm Climates
Principal Investigator: Beilman, David W
Licensed Year(s): 2013
Summary: The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...


Deltaic Lake Sediments as Recorders of Past Carbon Export from Arctic River Drainage Basins
Principal Investigator: Vonk, Jorien
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...


Permafrost Adjustment to Coastal and Deltaic Processes: Beaufort Sea and Mackenzie Delta
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....


Physical Limnology of Romulus Lake
Principal Investigator: Davidge, Gillian
Licensed Year(s): 1992
Summary: A limnological study of Romulus Lake (specifically temperature, salinity and suspended particulate matter) in association with the pattern of lake-ice development and inflow from the lake basin will be used to determine the effects of the modern hydrologic environment on the lake....


Mackenzie Delta Permafrost/Geology Transect
Principal Investigator: Dallimore, Scott R
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....


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....


1. Permafrost and Ground Ice of the Expedition Fiord Area; 2. An investigation of the Origin and Nature of Massive Ground Ice on the Fosheim Peninsula
Principal Investigator: Pollard, W.H.
Licensed Year(s): 1994 1992 1991 1990 1988
Summary: This research involves the field investigation of natural exposures of massive ground ice and bodies of surface ice. Sites identified in previous field seasons will be visited and samples of ice, water and sediment will be taken for further analyses. The results of this research will help in the interpretation of climate change and the assessment of both natural and human induced terrain disturban...


Investigation of Ground Ice Development in Sediments of the Mackenzie Delta Area
Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The Researcher and his team will continue to examine the hydrology of frost heave in the environment of a lake bottom. They will also conduct their study in land environments in the outer Delta and examine the distribution of ice in the upper layers of permafrost....


Coastal Geology of Northern Richards Island, Canadian Beaufort Sea
Principal Investigator: Forbes, D.L.
Licensed Year(s): 1991 1990
Summary: Geophysical surveys will be carried out from a 40-foot vessel and from 16-foot rubber boats to deploy current meters at two sites in water depths approximately 2 meters, to collect beach, cliff and seabed sediment samples and to survey beach and cliff morphology using theodolites and surveyors instruments....
