Biological responses to multiple environmental stressors in lakes around Yellowknife, NT
Principal Investigator: Smol, John P
Licensed Year(s): 2019
Summary: The main goal is to understand the spatial distribution of phytoplankton and zooplankton species in lakes around the Yellowknife area and provide environmental context to the ongoing paleolimnological (reconstructing the environmental histories of lakes) investigations. This year, the research team aim to collect phytoplankton and zooplankton from a suite of lakes around Yellowknife following ...

EKATI Engineering and Environmental Monitoring Programs
Principal Investigator: Lee, Claudine
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2014 to 2018 will be (1) to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment and air quality; and (2) to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be collected under ice using a 5L Niskin (a cylindrical PVC water sampler). During the week o...

The Bio- Magnification of Mercury within Fish Species of the Deh Cho and Their Varying Levels Among Lakes
Principal Investigator: Swanson, Heidi
Licensed Year(s): 2018 2017 2016 2016 2015 2014 2013
Summary: The objectives of this research project are to: 1) determine why fish mercury levels vary among lakes in the Deh Cho region; 2) identify best predictors of fish mercury levels; and, 3) determine which fish have the lowest levels of mercury and highest levels of micro-nutrients and fatty acids. The methods for this project include two parts, first is the collection of food web data from each lak...

Aquatic Effects Monitoring Program 2008
Principal Investigator: MacDonald, Gord
Licensed Year(s): 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
Summary: The objective of this study is to determine any seasonal variation in water quality, zooplankton & phytoplankton biomass and taxonomy, benthic invertebrate analysis and sediment chemistry, and will also include dust monitoring. Transportation will be by boat, snow machine, and helicopter. Samples will be taken for water chemistry, phosphorous & nitrogen, sediment, benthic invertebrates, zoopla...

2004 Baseline Aquatic and Fisheries Survey of Fox Pit Area
Principal Investigator: Granchinho, Sophia
Licensed Year(s): 2004
Summary: BHP Billiton has retained Rescan Environmental Services Ltd. to conduct a baseline aquatic and fisheries survey of lakes near the Fox Pit in the Koala Watershed on the EKATI claim block. The Fox Pit is the newest pit being constructed at EKATI. The wast...

Effects of Processed Kimberlite Effluent from the Ekati Diamond Mine, NT on Freshwater Zooplankton.
Principal Investigator: Liber, Karsten
Licensed Year(s): 2001
Summary: The research team will be transported to Long Lake by aircraft, and will travel by truck on the mine site. Sample collection will be carried out using a motorized boat. Water and phytoplankton samples will be collected using a 10 L Go-Flo water sampler. Zooplankton samples will be collected using a zooplankton net. There are three taxa of freshwater zooplankton that may be collected from Long ...

Polar Ecology Field Research
Principal Investigator: Curtis, Mark A.
Licensed Year(s): 1992 1989
Summary: The research scientists and graduate students involved are primarily interested in three topics in the aquatic ecosystems of the Igloolik region: (1) the species compostion of marine phytoplankton; (2) the cold adaptation physiology of polar cod; (3) the parasites of arctic char....

Biogenic Bromine Production in Arctic Waters and Ice Algal Physiology and Sea Ice Optics
Principal Investigator: Cota, Glenn
Licensed Year(s): 1994 1993 1992 1991
Summary: Some natural gases in air react with light and can cause ozone depletion near the earth's surface. Some of these gases are produced by marine plants or algae such as seaweeds and the small single-celled plants causing "brown ice". The researchers will find out what marine plants which contain and/or release these materials called "organohalogen gases". This study will help to determine how much ...

Nutrition and Distribution of Arctic Marine Zooplankton in Relation to the Physical Environment
Principal Investigator: Gustavson, Kent
Licensed Year(s): 1991 1990
Summary: The Researcher will continue to study the distribution of phytoplankton and zooplankton in the Barrow Strait area. The herbivourous plankton species which feed on the marine algae and phytoplankton is the first step in the arctic food chain. It is the herbivorous plankton which is the source of food for other animals which ultimately provides food for all other higher arctic animals....

Productivity of Marine Mammal Food Chains in the Northwest Passage
Principal Investigator: Welch, Harold
Licensed Year(s): 1993 1992 1991 1990 1988 1987
Summary: Dr. Welch and his project personnel will continue work on a study which began in 1984. The objective of the study continues to be the quantification of food web leading to marine mammal and bird production in the Canadian Marine Arctic....
