The water quality response of Arctic rivers to regional variability in landscape and permafrost conditions
Principal Investigator: Hille, Erika C
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5596. The objectives of this study are to conduct spatially detailed surveys of water quality and stream discharge along the Miner River, in order to examine how water quality responds to organic-rich peatland tributary streams and retrogressive thaw slumping; and, to examine the seasonal water quality of Caribou Creek and...


Terrain factors influencing the water quality of peatland streams along the Inuvik-to-Tuktoyaktuk Highway
Principal Investigator: Hille, Erika C
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5295. The objective of this project is to examine the oxygen (d18O) and hydrogen (d2H) isotopic compositions of stream water and precipitation for 11 peatland stream watersheds along the Inuvik-to-Tuktoyaktuk Highway (ITH). This information will be used to understand the hydrology of the contributing watershed. In particula...


Regional variability in the water quality of streams along the Dempster and Inuvik-to-Tuktoyaktuk Highway corridor
Principal Investigator: Hille, Erika C
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4743. The objective of this project is to compare and contrast the water quality of three watersheds with contrasting climatic and landscape characteristics, with the aim of identifying the climatic factors and landscape features that drive the water quality of streams located along the Dempster and Inuvik-to-Tuktoyaktuk Hi...


Impacts of Natural and Anthropogenic Disturbances on the Aquatic Health of Tundra Lakes in the Upland Region Northeast of Inuvik, NT
Principal Investigator: Hille, Erika C
Licensed Year(s): 2019
Summary: The objectives of this project are to examine the long term effects of thaw slumping on the water quality of water running off the landscape to the lakes and the lakes themselves, using data collected over the 10 year study period; and to examine the effects of tundra fire on the water quality of water running off the landscape to the lakes and the lakes themselves. This study will focus on 10 ...


Investigating the water quality of runoff from different terrain types
Principal Investigator: Hille, Erika C
Licensed Year(s): 2019 2018
Summary: The objectives are: 1) to examine how the water quality of streams varies spatially and determine what drives these differences (i.e., latitude, vegetation, surficial geology); and, 2) to examine how the water quality of streams varies temporally and determine what/how seasonal changes in water flow control water quality. The research team will collect water samples from a suite of study site...


Beaufort Sea Coastal Restoration – Exploring the Potential for Using Indigenous Plant Species to Revegetate Coastline Affected by Permafrost Thaw Slumping
Principal Investigator: Hille, Erika C
Licensed Year(s): 2021 2021 2020 2019 2018
Summary: The objectives include: 1) Creating a series of maps showing the thaw slump activity along the Beaufort Sea Coast near Tuktoyaktuk; 2) developing detailed water, vegetation, and ground temperature maps of the study sites using drones; 3) examining the effects of thaw slumping on the water quality of landscape-level runoff to the Beaufort Sea; 4) examining the effects of coastal erosion and thaw ...
