Permafrost slumping and land-water connections on the Peel Plateau
chercheur principal: Tank, Suzanne E
Année(s) de permis: 2024 2023 2022 2021
Résumé: This licence has been issued for the scientific research application No. 5953. The objective of this research is to understand how permafrost slumping increases the mobilization of carbon, nutrients, and toxins (mercury) from land to water, and the effects of this transport on stream ecosystems and the global carbon cycle. Over the next several years, the plan is to measure stream chemistry at ...


Seasonality of streamwater and icing chemistry in the Yellowknife, NT area
chercheur principal: Tank, Suzanne E
Année(s) de permis: 2022 2021
Résumé: This licence has been issued for the scientific research application No.5138. The objectives of this study are to determine the influence of permafrost thaw on the mobilization of carbon to stream ecosystems, and its subsequent effects on in-stream microbial communities and carbon cycling. The research team will measure stream water chemistry and collect water samples for microbial analysis at ...


The effects of fire on diverse aquatic ecosystems of the NWT
chercheur principal: Tank, Suzanne E
Année(s) de permis: 2017 2016
Résumé: The objective of this study is to determine the effect of fire on water quality within the southern Northwest Territories landscape. The research team will work across the Taiga Plains and Taiga Shield Ecoregions, because it is believed that differences in landscape between these regions will affect the catchment response to fire. The research team will also target catchments with variable permaf...


The effect of permafrost slumping on carbon delivery from land to water
chercheur principal: Tank, Suzanne E
Année(s) de permis: 2019 2018 2017 2016 2015 2014
Résumé: The objective of this study is to understand how permafrost slumping increases the mobilization of organic carbon from land to water, and the effects of this movement on stream communities. The research team will measure the concentration of stream-water organic carbon upstream and downstream of slump sites. The research team will also examine the fate of this carbon by undertaking incubation expe...


Degradation of dissolved organic carbon in Mackenzie Delta lakes and river channels
chercheur principal: Tank, Suzanne E
Année(s) de permis: 2013 2012
Résumé: This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. This water is then slowly...
