An investigation of arsenic speciation and toxicity in Baker Creek sediments from Giant Mine in the Northwest Territories, Canada
Principal Investigator: Nash, Tyler J
Licensed Year(s): 2012
Summary: The objective of this research project is to assess the sediment quality of Baker Creek. This will be achieved by analyzing factors influencing arsenic mobility from sediments to overlying water and assessing the toxicology of the sediments using exposure tests on indicator organisms. Core samples of Baker Creek sediments will be taken by the researchers using aluminum pipes driven into the gro...


The Use of Sediment Data as an Indicator of Aquatic Ecosystem Health in the Coppermine River Basin, NWT
Principal Investigator: Peramaki, Liisa
Licensed Year(s): 2000
Summary: This study will investigate the quality of aquatic sediment and evaluate its potential as an indicator of ecosystem health in the Coppermine River basin. Sediment cores will be collected by boat or float plane at Lac de Gras and Point Lake. The following field measurements will be recorded: water temperature and pH, and sediment colour, texture and pH. In addition, personal interviews will be c...
