Waste rock studies at a diamond mine site
Principal Investigator: Blowes, David W.
Licenced Year(s): 2014 2013 2012 2011 2010 2009 2008 2005
Summary: This research study is designed to investigate the processes related to water quality and quantity (collected at different scales) draining from country rock stockpiles that are located in areas of continuous permafrost. The quality of water draining from a country rock stockpile is determined by the combined effects of oxygen transport in the air phase, biogeochemical processes that control miner...


Reconnaissance Study of Smoking Hills
Principal Investigator: Dunfield, Peter F
Licenced Year(s): 2013
Summary: The objective of this work is to conduct a one day reconnaissance study of the Smoking Hills area. Mineral, rock, water and soil samples will be collected. Geochemical properties and microbial communities will be analysed in the laboratory in order to characterize any potential features unique to this site that would warrant future, more detailed research. The site will be accessed by helicopt...


Non-toxic arsenic in mushrooms and plants from Yellowknife
Principal Investigator: Reimer, Kenneth J.
Licenced Year(s): 2012
Summary: The objectives of this research is to: determine total arsenic and arsenic species in edible and non-edible mushrooms from contaminated and uncontaminated locations (mine properties and roadsides/parks); determine total arsenic and arsenic species in plants including Labrador tea, horsetails, buffaloberry, fireweed and berries (if available) from contaminated and uncontaminated locations (mine pro...


Surveillance and Cost Analysis of Respiratory Syncytial Virus Infections in Arctic Communities in Canada
Principal Investigator: Benerji, Anna
Licenced Year(s): 2010 2008 2008
Summary: Primary Objectives: 1) To identify the respiratory syncytial virus (RSV) and other respiratory viruses associated with lower respiratory tract infection (LRTI) admissions to regional and tertiary centres over a 18 month period for infants <1 year old living in the Canadian Arctic 2) To stratify the RSV LRTI admissions into categories by location (town with a hospital verses rural) and age (<1 ye...


Conceptual and Mechanistic Models for the Development and Survival of the Trichostrongylid, Ostertagia gruehneri, in Barrenground Caribou, With Respect to Northern Climate Change
Principal Investigator: Hoar, Bryanne M
Licenced Year(s): 2009 2008 2007
Summary: The objective of this study in 2009 is to determine if parasites (Ostertagia gruehneri) can survive on the tundra over winter. This is the third year of a three year study. This work is to study the parasite Ostertagia gruehneri. This is the most common stomach worm in barrenground caribou. Adult worms live in the stomach of caribou and eggs are shed in the feces of the caribou. Once in the env...


An Investigation of the Potential Impact of Climate Change on Infectious Gastroenteritis in the Canadian Arctic
Principal Investigator: Pardhan, Aliya
Licenced Year(s): 2009
Summary: This license has been issued for the scientific research application #928. The objectives of this research are: i) to define the burden of infectious GI illness including incidence of specific diseases, symptoms, hospitalizations ii) to characterize risk factors for exposure including geographic distribution of disease, impact of weather variables and potential impact of climate change iii) to ...


UV-B Impacts On The Microbial Food Web In High Arctic Freshwater Ecosystems
Principal Investigator: Vincent, W.F.
Licenced Year(s): 1994
Summary: There is increasing evidence that levels of solar UV-B radiation have begun to rise in the high Arctic. Little is known about microbial life-forms in the ecosystems of Arctic lakes and rivers and their UV-B resistance. A sampling hole will be drilled in the lake ice. These samples of zooplankton will be studied by a microscope. Samples of water and periphytic communites will also be taken. Underw...


Remote Sensing of Ocean Color in the High Arctic.
Principal Investigator: Cota, Glenn
Licenced Year(s): 1994 1993 1992 1991
Summary: Light leaving the ocean's surface can be detected remotely by satellite. With the proper conversion factors satellites can tell us the amount & growth of plant material in the oceans. Microscopic plants comprise the base of the marine food chain, serving as food for all animals. Because of their dark coloration plants absorb light & produce heat. We are studying what colors & how much light is abs...


Study of bio-indicators of environmental change in arctic lakes
Principal Investigator: Smol, John
Licenced Year(s): 1994 1993 1992
Summary: The researchers plan to take samples of lake water and lake sediments from a variety of sites in the region. From these samples, information will be collected about the water chemistry, microscopic organisms present in the lakes, and changes in the region's past environmental and climatic conditions....


The ecology, distribution and community structures of testate amoebae and diatoms on Devon Island.
Principal Investigator: Beyens, L.
Licenced Year(s): 1992 1987
Summary: To survey the testate amoebae and diatom communities on Devon Island and to make biogeographical comparisons with data obtained from other arctic regions. Samples will be taken of soil, mosses, lichens, mud and water....
