Licensed Year(s): 2023 2022 2017 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005
Summary: The objectives of this project are to: 1) continue to investigate trends in mercury, metals and persistent organic contaminants (POCs) in lake trout harvested from two locations (West Basin near Hay River, East Arm at Lutsel K’e) and burbot harvested from one location (West Basin at Fort Resolution) in Great Slave Lake in 2017 to further extend the long-term (1993-2015: POCs, 1993-2016 mercury a...


Landscape scale flooding in the Great Slave Lake Plain
Principal Investigator: Armstrong, Terry
Licensed Year(s): 2014 2013 2012 2011 2010
Summary: The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...


Impact of climate change on freshwater fish mercury levels
Principal Investigator: Stern, Gary
Licensed Year(s): 2012
Summary: The objective of this study is to collect fish from lakes and tributary rivers of lakes under fish (mercury) consumption advisories and compare with older data from government if available (DFO, Environment Canada), and to collect and analyse sediment cores from these lakes to see how lake ecosystem changes relate to fish mercury levels. There are two main methods involved in this work. For fis...
