Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4759. The overall objective of this research is to assess the permafrost thaw slump erosion and transport of its sediment by rainfall/runoff to depositional zones within Arctic tundra lakes. To achieve this, we will link a rainfall simulator with an annular flume (to simulate lake currents) located in the Hydro-ecology Moni...

Licensed Year(s): 2020 2019
Summary: This licence has been issued for the scientific research application No.4678. The research team will collect a new sample set to better quantify the carbon source, age and fate in one of the largest rivers draining the high latitudes. Based on previous work, the team have identified three priority objectives for sample collection in the Mackenzie River: 1) Collect river depth profile sediment ...

Principal Investigator: Bogen, Jim J
Licensed Year(s): 2010
Summary: The objective of this research is to estimate the modern and historical fluxes of sediment- associated chemical elements to the Arctic Ocean and their relationships to natural and man-induced changes in sediment yields and sediment sources and if possible, predict the impact of future climate changes on the fluxes. The study will include sampling of overbank sediments from floodplains and del...

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: This study is designed to fill science gaps in Environment Canada’s understanding of the structure and functioning of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project. While data collected during the Environmental Impact Assessment studies (carried out in conjunction with the proposed construction and operation of the Mackenzie Gas Pipeline) are relative...

Principal Investigator: Lesack, Lance
Licensed Year(s): 2008 2007
Summary: The Arctic Ocean receives much higher river inflows than other ocean basins and this has major implications for sea-ice formation, for nutrient supply to the base of aquatic marine foodwebs, and for optical properties of ice-free areas and ice-pack margins via fluxes of dissolved organic matter and riverine particles. The Beaufort Shelf is strongly influenced by Mackenzie River outflows. However, ...

Principal Investigator: Graburn, Larry
Licensed Year(s): 2004
Summary: This research forms part of an aerial reconnaissance program to observe the characteristic break-up patterns at selected watercourse crossings along the proposed pipeline right-of-way from the Deh Cho region in the south to the Inuvialuit Settlement Regi...

Principal Investigator: Forbes, Donald L
Licensed Year(s): 2004
Summary: Safe and sustainable hydrocarbon development and potential impacts of climate change on coastal infrastructure and subsistence activities require improved knowledge and understanding of coastal and nearshore seabed properties, and coastal hazards such as...

Principal Investigator: Burn, Chris R
Licensed Year(s): 2002
Summary: The wind abraided rocks 3 km south of Paulatuk are among the best examples of ventifacts in North America. The rocks have smooth, lichen-free surfaces on their south side, which are blasted by sand and snow during strong southerly winds in winter. The re...

Principal Investigator: Coulombe-Pontbriand, Moise
Licensed Year(s): 2002
Summary: The study will attempt to reconstruct the past 10,000 year geomorphological and hydrological history of the Mackenzie River using sedimentological records of fluvial deposits. The researcher will travel by Zodiac boat from Jean-Marie River to Point Separ...
