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. Patterned ground marked by ice-wedge polygons is formed by freezing and thawing of the soil, which forms cracks into which ice can spread and cause the soil to uplift. These processes have effects on the hydrology and water chemistry of a...

Licensed Year(s): 2009 2008 2007 2006
Summary: This licence is being issued for the scientific research application no. 977. The objective of this study to examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. The researchers will measure the following: nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and ...

Principal Investigator: Vincent, Warwick F.
Licensed Year(s): 2004
Summary: The aim of this research is to define the influence of the Mackenzie Delta floods on the biological processes and patterns that persist in these shallow water ecosystems. The researchers are looking for links between the sediment on the bottom of the lak...

Summary: The long term goal of this research is to develop a biogeochemical model for lakes in the Mackenzie Delta, and ultimately, a more generalized ecosystem model for floodplains and deltas of major world rivers that will facilitate assessing the effects of m...

Licensed Year(s): 2001 2000
Summary: Selection of lakes for this program was based on: size (diameter/depth); fish over-wintering potential; connectivity with other waterbodies; and the likelihood of intensive (3D) seismic activity occurring within the lakes during the winter of 2001-02. A total of 6 lakes have been identified for inclusion in the survey. Three alternate lakes have also been identified in the event that those selec...

Principal Investigator: Metikosh, Serge
Licensed Year(s): 2001
Summary: The research team proposes to collect information about fish habitat features and use of selected delta lakes. The selection of the lakes to study will be determined during the reconnaissance level survey and will largely be driven by their proximity to the production field, the gathering system and pipeline corridor. Additional water quality information will be collected at ten of the selected ...

Summary: The Research will continue to examine the hydrology of frost heave in the ideal environment of a lake-bottom. In addition some experimental trials of frost heave in equipment of various sizes will be conducted in winter time. Summer activities are planned in the outer Delta to examine the distribution of ice in the upper layers of permafrost and to investigate permafrost conditions beneath shallow...

Principal Investigator: Marsh, Philip
Licensed Year(s): 1993 1992 1991
Summary: The research will study changes in the water levels of a variety of lakes in the Mackenzie Delta. Investigations will include consideration of factors controlling the lake levels, introduction of floodwater from the Mackenzie River, rainfall on to the lake, smowmelt runoff into the lakes and evaporation from the lakes....

Principal Investigator: McCart, Peter
Licensed Year(s): 1977
Summary: To conduct a study on the effects of sedimentation on northern lakes resulting from development activities. Results will be use dto suggest acceptable rates of sedimentation to preserve the reproductive capacity of lakes in the north....
