Résumé: 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...

Résumé: 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...

Résumé: 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...
