Objective(s): To investigate organic contaminant concentrations in surface sediments; to examine historic deposition rates of sediments in 2-3 regions of Great Slave Lake (Hay River, the Slave River delta and the channel region east of the Slave River); to investigate organic contaminant concentrations in invertebrates in the vicinity of the Slave River outflow (as time and funds allow).
Project Description: Researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Hay River, the Slave River delta and the channel region east of the Slave River. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect small animals (invertebrates) which are eaten by fish as part of an overall study which examines contaminants in the lake's ecosystem.
