Summary: Through this research the team will answer the following questions: 1. From the outer Slave River Delta (SRD) to the apex of the SRD, what is the current status of nutrients and contaminants in SRD wetland ecosystems? 2. How do trace elements (e.g., mercury) move through SRD wetland food webs? 3. How does water source affect the availability of nutrients and trace metals in SRD wetlands? Wet...

Summary: The main objective of this project is to develop wetland inventory for south western NWT that will be used to provide a baseline for many kinds of planning (including updates to the land use planning processes) and research in support of biodiversity conservation and sustainable management of habitat. Specific objectives are to: 1) develop and use computer-based methods to produce wetland maps wi...

Summary: The research team will conduct a comprehensive wetland plant community vegetation analysis along Bakers Creek with a focus on the lower stretch of the creek. In addition soil samples will be obtained for an assessment of soil dwelling fungal communities. The assessment will include emergent vegetation along riparian areas as well a floating leaved, free floating and submerged vegetation in the ...

Summary: The objective of the winter field survey is to determine and record lakes where ice has frozen to the bottom and areas where floating ice is present. Along with obtaining this information, snow depth, ice thickness, ice type, photos, and local weather conditions will be recorded. The objective of the summer field work is to observe broad wetland types and the extent and presence of submerged aquat...

Summary: To determine how spring and summer temperatures affect the abundance of the amphipod Gammarus lacustris throughout the summer. Over the 2 years of the experiment, the research team plans to use amphipods from 4 different sources over several latitudes (Montana-USA, St. Denis-SK, Yellowknife-NT, Inuvik, NT). Using this variety of geographic sources will allow us to assess if different populations...

Summary: The objective of this research is to assess the performance of lagoons and wetlands in the treatment of municipal wastewater in Canada's Arctic. A secondary objective is to determine the occurrence of trace contaminants in northern wastewaters. Samples will be taken from the influent (raw sewage) and effluent (treated wastewater) of each lagoon and wetland system in the communities where the r...

Summary: The objective of this study is to identify how arsenic is bound in the sediments, and determine the role of microbial activity in arsenic mobility. It is anticipated that the results of this research will benefit the design of a constructed wetland, which is expected to be part of site remediation. The researchers propose to sample sediments and surface and pore water from the Ho-Hum Lake wetla...

Summary: Arsenic was introduced to Ho-Hum Lake when it was used as a tailings pond during mining activities at Terra Mine, of the Silver Bear Mines Group. The objective of this study is to determine how arsenic is being removed from the lake water by a wetlands area. The intention for collecting data will include water and sediment sampling in Ho-Hum Lake, Moose Bay, and the wetlands between them. Seq...
