Factors affecting river turbidity in a degrading permafrost environment: the Tasiapik River, Umiujaq (Nunavik)
This study focuses on spatiotemporal changes in water turbidity in relation to permafrost to document the impact of meteorological conditions and water flow on hydro-sedimentary processes in northern regions. Starting in June of 2019, water turbidity data were collected at six sites along the Tasiap...
