EL462 and EL463 Aggregate and Permafrost Mapping - Geophysical Survey and Confirmatory Drilling
Principal Investigator: Hansen, Ken
Licensed Year(s): 2013 2012
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...


Investigation of a possible impact structure on Victoria Island, NWT
Principal Investigator: Osinski, Gordon
Licensed Year(s): 2015 2012
Summary: The objectives of this research are to: (1) Confirm of a meteorite impact origin for the Collinson Inlet structure. In order to confirm the meteorite impact origin of this structure, unequivocal shock metamorphic criteria need to be documented. Shatter cones are the only diagnostic shock effect visible to the naked eye (French and Koeberl 2010). The research team will seek out the potential s...


Long term river flow and climate conditions reconstructed from lake sediments
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2012
Summary: The research team seeks to obtain sediment cores from two lakes in order to reconstruct past river flow in the region. This work, which builds on similar efforts at "Shellabear" lake, NWT, and work at Cape Bounty (Nunavut), will focus on long term river flow characteristics and the climate factors that control them. The fieldwork involves augering a hole in the lake ice and lowering a tube int...


Diavik Aquatic Effects Monitoring Program 2011
Principal Investigator: Moore, Kristin M
Licensed Year(s): 2024 2023 2022 2021 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: To revisit fixed sample stations over the course of a year in an effort to determine any seasonal variation that may exist and confirm impact predictions. The study will encompass the following water based parameters: water quality, zooplankton & phytoplankton biomass and taxonomy, benthic invertebrate analysis and sediment chemistry. This program also includes dust monitoring and fish health. ...


Flux of sediment-associated chemical elements in rivers draining to the Arctic Ocean
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...


Timing of glaciation and uplift of the Richardson Mountains and connection to Old Crow basin, northern Yukon
Principal Investigator: Froese, Duane G
Licensed Year(s): 2010
Summary: The objectives of this study are to observe and document sediments exposed along the upper Rat River, also to collect samples of sediments for potential radiocarbon dating. Researchers will fly into area via helicopter from Old Crow. Where possible the helicopter will land adjacent to river escarpments for access to large river bars or wide banks. Researchers will climb up banks to observe sedi...


Biological Studies of Waters Along the Proposed Mackenzie Gas Project Pipeline Route - Gwich'in Settlement Area
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2009 2008 2007 2006
Summary: This licence is being issued for the scientific research application no. 983. The objective of this study to examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. The researchers will measure the following: nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and ...


Slave River Hydro Development
Principal Investigator: Wilbur, Steve
Licensed Year(s): 2008
Summary: This licence is issued for the scientific research application # 926. The goal of this river geomorphology program is to describe the Slave River’s channel landforms and sediment characteristics and assess the sensitivity of these river landforms to potential changes in stream hydrology. Field visits will include a reconnaissance flight via helicopter along the Slave River (from Fort Smith ...


Timing and genesis of the Eagle meltwater channel in northern Yukon: Implications for the northwestern Laurentide margin
Principal Investigator: Kennedy, Kristen
Licensed Year(s): 2008
Summary: The objective of this study is to observe and document sediments exposed along the upper Rat River, and collect samples of sediments for potential radiocarbon dating. Researchers will fly into area via helicopter from Old Crow. Where possible (large river bars or wide banks), helicopter will land adjacent to river escarpments for up to 2 hours. Researchers will climb up banks to observe sedimen...


Regional Geochemistry Survey, Mackenzie Mountains NWT
Principal Investigator: Falck, Hendrik
Licensed Year(s): 2007
Summary: The objective of this study is to collect stream silts on first order streams on a regional basis at a density of one sample every 13 Km2 across the target area. Heavy mineral concentrate samples will be collected at a density of one sample every 25 km2. The samples will be dried, labeled and shipped to various laboratories for cataloging and analysis. A team of 2 field workers would use a heli...
