Summary: The objectives are to measure a suite of trace elements and isotopes (TEIs) in the active layer and permanently frozen layer of permafrost cores sampled near the Mackenzie River, and to compare these concentrations to those observed in submarine groundwater discharge and Mackenzie River discharge in order to determine whether permafrost-associated TEIs are being transported to the coastal Arctic. ...

Summary: The research project Water Ecosystems Monitoring using Earth Observation aims to define an Earth Observation (EO) driven monitoring program to provide information towards monitoring environmental indicators of northern ecosystem health. Once the project is done information on water indicators including water temperature, suspended sediment concentrations, water levels, and ice quality and will be ...

Summary: The objective of this project is to evaluate bryophytes regeneration in Northwest Territories burned peatlands to improve the understanding of the structure of mosses ecosystems. This new knowledge should improve the restoration method of disturbed peatlands where the reintroduction and regeneration mosses are problematic. Several sites will be studied in order to have a range of plant communit...

Summary: Understanding the integrated eco-hydrological behaviour of ecosystems in the context of thawing permafrost is a major challenge. To meet this, the research team will measure the present surface and near-surface water supplies and their inter-annual variability assuming a condition of no permafrost thaw. The team will also develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bog...

Summary: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Permafrost thaw in lake catchments may cause increased transport of organic carbon and dissolved nutrients to lakes with effects on the hydrology and water chemistry of lake environments. Patterned ground marked by ice-wedge polygons is f...

Summary: There are two primary goals of this project: 1) to determine whether relatively small Canadian Arctic rivers significantly contribute to the total volume of freshwater that drains through Davis Strait; and, 2) to determine if they are chemically distinct from larger North American rivers such as the Mackenzie and Yukon Rivers. To achieve these goals the research team propose to collect water sampl...

Summary: The study is to continue establishing the groundwater and surface water conditions within the exploration licences prior to and during oil and gas exploration activities. Surface Water Quality Sample Collection Collect surface water samples once, during September 2015, from a reduced number of sampling locations targeted near areas where exploration activities have occurred. The water sampl...

Summary: The first objective is to conduct a combined Phase I/II Environmental Site Assessments for a buried pipeline located within the municipality of Fort Resolution, Northwest Territories. The second objective is to identify any health and safety concerns associated with the buried pipe line. A records review and gap analysis will be done to synthesize the information that the research team have o...

Summary: The objective of the 2015 hydrotechnical assessment is to assess the known and potential watercourses along the proposed access road alignment. The 2015 geotechnical assessment will assess the terrain along the proposed access road alignment and the potential material sources within the project area. Observing the known and potential crossings along the alignment. During the field work the fo...

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...
