Effect of Shoreline Subsidence and Anthropogenic Activity on Northwest Territories’ Lakes.

Adam James Houben
Thawing permafrost – in the form of shoreline retrogressive thaw slump events – influence adjacent arctic tundra lake systems near Inuvik, NT. Slump-affected lakes demonstrated lower organic matter and key nutrients such as phosphorus (P), as well as greater water clarity. Key terrestrial permafrost soil indicators such as U, Sr, and Li, were identified to be elevated in slump-affected lakes, while other more biologically important metals (e.g. Fe, Mn) were significantly lower in affected lakes....
