Topic: The long-term ecological consequences of gold mining operations, urbanization, and climatic changes on sub-Arctic lakes near Yellowknife (Northwest Territories, Canada). Overview:  The lack of long-term environmental monitoring data poses significant challenges to understanding the impacts of past anthropogenic activities on freshwater ecosystems. However, we can use natural archives (e.g. lake sediments that accumulate continuously) to fill this knowledge gap.
