Bioaccumulation of Brominated Flame Retardants, Currently Used Pesticides, and emerging metal trends in the Vegetation-Caribou-Wolf Food Chain
Principal Investigator: Katz, Sharon
Licenced Year(s): 2009
Summary: The objectives of this study are: (a) To determine whether brominated flame retardants (BFRs), current use pesticides (CUPs), perfluorinated compounds (PFCs), and mercury bioaccumulate using the vegetation-caribou-wolf food chain and the Bathurst caribou herd as a model; (b) To explore possible sources of lead contamination in the Bathurst herd caribou; (c) To elucidate the pathway of lead uptake ...


Bioaccumulation of Perfluorinated Compounds in the Vegetation-Caribou-Wolf Food Chain - Traditional Knowledge
Principal Investigator: Katz, Sharon
Licenced Year(s): 2008
Summary: The objective of this research is to obtain traditional knowledge (TK) about: the feeding and preying habits of wolves; the relative importance of caribou in wolves' diet; the composition and seasonality of wolves diet; wolves’ prey preference; the composition and seasonality of caribou diet; caribou and wolf and oral history information, and compare TK from different regions. The Gwich'in Soci...


Harnessing River Current Power with Helical Gorlov Turbines
Principal Investigator: Katz, Sharon
Licenced Year(s): 2007
Summary: The goals of this study are: to develop an understanding of water and ice behaviour in sites on the Mackenzie and Great Bear rivers; to obtain knowledge of water speed, depth, current profile, frazil ice and how deep ice may reach into the rivers during the Spring break up; to use this information to determine the feasibility of using Ducted Venturi and Gorlov Helical Turbines (DV-GHT) to harness ...


Contaminants in Medicinal Plants: Labrador Tea
Principal Investigator: Katz, Sharon
Licenced Year(s): 2007
Summary: The objectives of this project are to determine the levels of lead (Pb), zinc (Zn), iron (Fe) and copper (Cu) in edible plants in the area between Pine Point, a site of a closed Pb/Zn mine, and Fort Resolution; to determine the levels of lead (Pb), zinc (Zn) and iron (Fe) and copper (Cu) in edible plants along the railroad track between Pine Point and Hay River; to use data collected on an interce...


Metals Uptake from Vegetation to Caribou in the Canadian Arctic
Principal Investigator: Katz, Sharon
Licenced Year(s): 2007
Summary: The monitoring objectives of this project are: to conduct a targeted scientific program to analyze heavy metals and trace elements and stable isotopes in vegetation (caribou food); to correlate the results in vegetation with concentrations in caribou from a related NCP program [Gamberg 2006]; to test if contaminant patterns in caribou tissues will vary with patterns observed in lichen/moss, or wil...


Mushroom Cultivation
Principal Investigator: Katz, Sharon
Licenced Year(s): 2006
Summary: The objective of the project is to create a fresh, nutritious, cheap food source to supplement the northern diet, and to increase awareness of healthy diet. In the future the hope is to extend this project to create a cottage industry employing local people. The project will involve composting straw, and manure or synthetic compost. The compost is wetted and aired, nitrogen supplements and gyp...


Inuvik Dumpsite Fire
Principal Investigator: Katz, Sharon
Licenced Year(s): 2006
Summary: This project aims to address a local concern about the release of contaminants resulting from an enduring fire at the Inuvik dumpsite by complementing the monitoring of Inuvik’s dumpsite for non-standard contaminants, and by reaffirming the drainage pathways from the dumpsite. Water samples (40-80 l) will be collected from two streams that clear the melt water from the dumpsite area, and the t...


Qiviuq Collection
Principal Investigator: Katz, Sharon
Licenced Year(s): 2005
Summary: The objectives of the research are to: investigate ways of introducing man-made items into musk ox habitat with minimal disturbance; observe if wild musk oxen will physically interact with a man-made addition to their habitat; test the efficacy of the “muskombs” (scratching posts for musk oxen); and collect qiviuq (musk ox down wool). The results of this research will be presented to Inuvialuit gr...


Natural Dyes
Principal Investigator: Katz, Sharon
Licenced Year(s): 2005
Summary: The objectives of this study are to: build a compendium of Northwest Territories' dyes; develop protocols for medium-scale, reproducible dyes; produce dyes from non-traditional sources available in the region; provide dyes for northern arts and crafts; and, obtain information needed to establish a community-based dye industry in NWT communities. The researchers will conduct interviews of elder...
