Objective(s): To determine how the recent and dramatic climate changes in Arctic freshwater have affected the transport and fate of anthropogenic contaminants to freshwater systems, two of the largest threats facing northern communities and ecosystems.
Project Description: This research will determine how the recent and dramatic climate changes in Arctic freshwater have affected the transport and fate of anthropogenic contaminants to freshwater systems, two of the largest threats facing northern communities and ecosystems. This research will develop new tools to examine how the fate of anthropogenic contaminants is affected in Arctic regions under different climate change conditions. Specifically, this research will: (1) determine chronologies of pollutant deposition in Arctic lakes strategically selected to span a gradient in climate change, and assess temporal trends in relation to ecosystem productivity and structure (e.g., beta-diversity and assemblage structure of diatoms) and organic matter deposition; (2) determine how warming-related factors affect the delivery of dissolved organic carbon in Arctic lakes; and (3) develop microbial bioreporters that can be used to assess the bioav...
