Tracing the Origin of Mercury Contamination in the Lakes and Fish of the Jean Marie River First Nation Lands
Principal Investigator: Laurent, Cyrielle C
Licenced Year(s): 2015
Summary: The short term objectives for this project are to: - Assess permafrost as a possible origin of mercury contamination; - Measure mercury content in permafrost samples; - Engage the community to exchange traditional and scientific knowledge to better understand relationships between country food, water quality, and permafrost degradation from a contamination perspective; and - Use traditional la...


Traditional Ecological Knowledge of Capelin in Darnley Bay, NT
Principal Investigator: McNicholl, Darcy G
Licenced Year(s): 2015
Summary: The primary aim of this project is to synthesize community-based observations over multiple years as traditional knowledge with results obtained by biological surveys conducted in the Darnley Bay nearshore habitat. This information will contribute to understanding how Capelin function in Arctic marine food webs and how that is subject to change in a warming climate. Local observations of Capel...


Cassette Islands Project
Principal Investigator: Paulette, Cochise
Licenced Year(s): 2015
Summary: The short term objectives of this project are to: 1) Document and present and historical data on the local environment and wildlife; 2) Assess the impacts of climate change on our community's health and food security; 3) Support intergenerational knowledge sharing between elders and youth on the land; 4) Engage our community in the research; 5) Build traditional knowledge capacity in our com...


ARCTICFIRE
Principal Investigator: Pumpanen, Jukka S
Licenced Year(s): 2015
Summary: The aim of the ARCTICFIRE project is to study the long term effects of natural forest fires on the decomposition of soil organic matter in the northern arctic and subarctic forests. The research team will study the changes in size and quality of soil carbon and nitrogen pools and fluxes after forest fires and their underlying processes in the arctic and subarctic zone, especially the interactions ...


Cumulative Impacts Monitoring of Aquatic Ecosystem Health of Yellowknife Bay, Great Slave Lake
Principal Investigator: Chételat, John
Licenced Year(s): 2015
Summary: The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study: 1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)? 2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay? 3) How much of ...


Noell Lake Ice Study - Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2015 2014 2013 2012 2011 2010 2009
Summary: The overall objective of this research is to improve the knowledge on lake ice and its effect on food webs/productivity in small Arctic lake systems in order to better predict changes that could occur under changing climate. The research involves the automated ice buoy and instrumented subsurface mooring system for continuous monitoring of weather conditions, lake ice cover (formation, growth o...


Sahtu Youth Network for a Regional Action Plan on the Health Impacts of Climate Change
Principal Investigator: Simmons, Deborah L
Licenced Year(s): 2015
Summary: The short-term objectives for the project are to: 1. Review and build on learnings from previous climate change and health adaptation projects in Tulít’a, Fort Good Hope and Déline, both in terms of the content and the methods used. 2. Strengthen action capacity, leadership and skills through creation of a Sahtu Youth Network for research and action planning on climate change and health. 3. Com...


Responses of trees and shrubs to climate warming at high latitudes
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2015 2014
Summary: The objective of this project is to determine the growth and recruitment responses of trees and shrubs to changing climate conditions near tree line and to study drivers of shrub expansion on the tundra. To accomplish these objectives, researchers will measure long-term tree and shrub growth at Havikpak and Trail Valley Creek using tree/shrub ring analysis. Specifically, at each site, small wo...


Water and leaf wax isotopes in permafrost
Principal Investigator: Porter, Trevor
Licenced Year(s): 2014
Summary: The primary objectives of this research project are to collect frozen core samples from the top of permafrost and soil from the active layer. Boreal sites will be targeted. The stable isotope compositions of ice and leaf waxes from the samples will be measured. Samples collected from NWT will be added to a much larger Yukon dataset, and the relations between regional climate and the proxies will b...


Long term and current variability in sources and sinks of carbon and nitrogen in terrestrial and aquatic ecosystems underlain by discontinuous and continuous permafrost
Principal Investigator: English, Michael C
Licenced Year(s): 2014
Summary: The objectives of this research project are: 1. to extract sediment cores from three different regions of the Northwest Territories namely: the low arctic tundra (continuous permafrost-Daring Lake), Taiga Shield northern boreal (widespread discontinuous permafrost-Wekweeti), and Taiga Shield boreal (sporadic discontinuous permafrost-Baker Creek Watershed) which provide the research team with a re...
