The overarching objectives of this research are two-fold:
1)To investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and
2) To investigate the toxicological consequences of ...

Summary:
The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study:
1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)?
2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay?
3) How much of ...

2013 Summary:
Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...
