Sediment inputs from retrogressive thaw slumps drive algal biomass accumulation but not decomposition in Arctic streams, NWT

Increasing rates of precipitation and higher air temperatures have increased the size and frequency of retrogressive thaw slumps—large depressions of thawed permafrost that form on the landscape—in north‐western Canada. Many of these thaw slumps flow into nearby stream systems, leading to increased sediment, solute and nutrient loads. We evaluated the impacts of retrogressive thaw slumps on measurements of algal biomass accumulation and...
