Summary:
This licence has been issued for the scientific research application No. 5970.
1) To assess the impact of recent 2023 wildfires on the aquatic ecosystem in small ponds in the Dehcho and South Slave area.
2) To assess whether small ponds impacted by the 2014 wildfire season had recovered to pre-fire conditions.
3) To assess whether there were cumulative impacts of repeated wildfires on small ...

20192018 Summary:
This licence has been issued for the scientific research application No.4734.
The objective of this research is to identify impacts of climate change and permafrost thaw on pond methane emissions, and on water chemistry in streams that drain peatland-rich catchments. Impacts on methane emissions will be assessed.
Specific objectives are: 1) to characterize the trends and variability in magn...

2018 Summary:
The goal is to reconstruct long-term environmental change (hundreds to thousands of years) by examining chemical and biological fossil remains preserved in lake sediment cores, in order to better understand how thawing permafrost impacts lake ecosystems.
1) Water chemistry and plankton survey
The research team will collect lake water samples from the study lakes to analyze for water chemistry...

20172016 Summary:
The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the past; 2) are fires becoming more frequent/severe due to the impacts of climate change; 3) what impact does wildf...

20162015 Summary:
The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change.
Given the overall objective of the project, the team intend to address five research questions:

Summary:
The Objectives of this research are to:
1) determine where the participating communities obtain their drinking water from within their home and while on the land and why; and determine the areas of each region that are considered valuable and important areas of water quality; and
2) determine what the concerns are concerning the sources of water, both within the homes and natural water sources, ...

Summary:
The main objective of this one year project is to provide the community with a practical tool for assessing Jean Marie River’s (JMR’s) vulnerability to food security in relation to country foods, as well as the vulnerability of sources of country foods and drinkable water used by the community members out on the land, in the context of climate change. This tool will consist of a mapping of permafr...

2011
Summary:
The goal of this research project is to measure the concentration and composition of natural dissolved organic carbon in rivers along a latitudinal transect from central Alberta to southern NWT. Data on water quality will be combined with spatial data that describes the drainage basins of the sampled rivers, e.g. ecosystem composition, size, slope, recent fire impact and permafrost conditions. The...

The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...
