Principal Investigator: Fichot, Cedric
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5897. The primary objective of this funded project is to develop a sophisticated model that can simulate the mobilization, transport, transformations, and export of tDOC from the Mackenzie River watershed to the Arctic Ocean. The model will be used to simulate the transfer of tDOC during the past two decades and for plausi...

Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5751. The project aims to directly observe seasonally strongly variable organic carbon concentrations and chemistry of the Mackenzie River and thus its fluxes to Arctic coastal waters. We aim for weekly observations of Mackenzie River biogeochemistry resolving the major phases of the hydrological year (winter under-ice flo...

Summary: This licence has been issued for the scientific research application No.5542. The proposed project aims to directly observe seasonally strongly variable organic carbon concentrations and chemistry of the Mackenzie River and thus its fluxes to Arctic coastal waters. The research team aim for weekly observations of Mackenzie River biogeochemistry during a period covering the major phases of the h...

Principal Investigator: Bourdages, Madelaine
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5224. The first objective of this project is to quantify microplastic concentration and composition in water, sediment, zooplankton, and air around Great Slave Lake. The second objective of this project is to examine if microplastic concentrations are greater near communities than the open water of Great Slave Lake. The thi...

Principal Investigator: Hansen, Jeremy R
Licensed Year(s): 2017
Summary: The objective is to investigate a disturbed slump site and an undisturbed river bank to measure and compare what is possibly melting/flowing/leaching into the river system possibly due to climate change. Physical descriptions of both sites combined with temperature, potential of hydrogen (pH), TSS (total suspended solids), TDS (total dissolved solids), and turbidity will be collected, analysed, an...

Principal Investigator: Swallow, Michelle N
Licensed Year(s): 2014
Summary: The objectives of this research are: (1) to gain input from practicing NWT elementary school teachers about the design features for an online learning environment and resource focused on the Mackenzie River and system; (2) to develop a prototype of a WWW site for use by teachers and students in learning about the Mackenzie River; and (3) to field test the prototype WWW site with representative edu...

Principal Investigator: Millar, Nathan P
Licensed Year(s): 2006
Summary: This study involves the determination of the population structure of fish in the Mackenzie River. Specific objectives include the delineation of stocks of three fish species: loche (Lota lota), crookedback (Coregonus clupeaformis) and coney (Stenodus leucicthys), and the identification of downstream fisheries as mixed-stock or single-stock fisheries. A population genetics approach will be employed...

Principal Investigator: Couture, Rejean
Licensed Year(s): 2006 2005
Summary: The main objectives of the field reconnaissance at landslide sites are as follows: o To visit landslide sites that exhibit on-going movement in order to qualify the rate of movement; o To identify main failure mechanisms and factors that contributed to slope failures; o To validate previous data collected through airphoto interpretation and remote sensing techniques; o To collect soil samples ...

Principal Investigator: Guo, Laodong
Licensed Year(s): 2005 2004
Summary: The purpose of the study is to better understand how climate and environmental changes affect river water chemistry and material export fluxes, and in turn, how biogeochemical tracers can be used to examine the impacts and biogeochemical consequences of environmental changes. This is the second year of a three-year study. The researchers plan to sample the Mackenzie River starting in late Apri...

Principal Investigator: Dick, Terry A.
Licensed Year(s): 2004
Summary: This research will study small second order streams entering the Mackenzie River in order to 1) develop descriptors to measure physical aspects of small stream environments; and 2) determine which biological organisms to use to monitor stream health. Nin...
