Impact of esturine cation exchange reactions on the true carbon export budget of the Mackenzie river.
Principal Investigator: Tipper, Edward
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5269. This project will determine the impact of cation exchange between minerals and surface waters and quantify the release from the exchange pool as fresh water enters the oceans. This will be achieved through careful sampling of suspended sediment and water from regions of fresh to saline waters of the Mackenzie River. ...


Understanding how alluvial fans form in periglacial environments
Principal Investigator: Palucis, Marisa C.
Licensed Year(s): 2019
Summary: The research team are proposing to conduct a detailed characterization of one alluvial fan located near Aklavik. The team want to assess how the alluvial fan is developing, determine the role of melted ground ice and snow in transporting sediment from the Aklavik Range to the alluvial fan, and sort out whether these alluvial fans have characteristics that can be identified on Mars. Once on the ...


Heavy mineral indicator tracing in glaciated terrains
Principal Investigator: Kjarsgaard, Bruce
Licensed Year(s): 2012 2011
Summary: The objective of this study is to improve understanding of transportation and deposition of heavy minerals in surficial materials (till and esker systems). The study area is approximately 60 x 100 km, is located east of Thaydene Nene National Park, and adjacent to the Quaternary ice divide. Work on the ground, over a 2 week period, will involve sample collection of surficial materials in order...


Deltaic Lake Sediments as Recorders of Past Carbon Export from Arctic River Drainage Basins
Principal Investigator: Eglinton, Timothy I
Licensed Year(s): 2011 2009 2007
Summary: This licence is being issued for the scientific research application no. 955. The objective of this research is to collect sediment cores from the Mackenzie River Delta in order to study how the river has behaved in the past, and see if the researchers can detect recent changes due to thawing permafrost. More specifically, the goal is to determine whether the researchers can reconstruct past c...


Sediment Transport Processes in Canyon Creek, Sahtu Settlement Region
Principal Investigator: Rempel, Laura L
Licensed Year(s): 2006 2005
Summary: The aim of this study is to characterize sediment transport processes, including bed scour and fine sediment deposition, in a sub-arctic stream intersected by the proposed Mackenzie Gas Pipeline. The specific objectives of the study are: characterization of surface and sub-surface bed sediment texture for all habitat types; measurement of bed scour depth and transport distance of sediment due to ...


Particle Dynamics on the Mackenzie shelf (CASES sub-project)
Principal Investigator: Walker, Tony R
Licensed Year(s): 2005 2004
Summary: The Beaufort Sea shelf is very shallow and the Mackenzie River, which sends freshwater, nutrients, and particles onto the shelf, may have a large influence on its productivity. The researchers would like to study the effects of the river in transporting particles to the shelf by measuring the types of particles, how fast they sink, and how easily they are stirred from the bottom. They would also ...


Wind-abraided rocks near Paulatuk, NT
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...


Using Tree Rings and Lake Sediment to Reconstruct Streamflow and Climate in the Northwest Territories
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2002
Summary: The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...


Reconstructing Holocene history of the Mackenzie River Valley from fluvial sediment records, Fort Simpson to Arctic Red River
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...


Arctic Sand Sheet Development
Principal Investigator: Murton, Julian B
Licensed Year(s): 2005 2001
Summary: The research team will operate from two fly camps beside the northern coast of Liverpool Bay, and two camps in the Mason Bay area in the northest portion of Richards Island. Transportation to the camps will be by float plane and boat. All human waste will be buried, and all non-burnable waste will be packed out. Equipment used will consist of shovels and trowels to clear slumped sediment from co...
