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...

The goals of this research are to examine: 1) measurements of water depths and lake depths for selected area of the Mackenzie Delta; 2) changes in lake flooding and historical lake boundaries in the Mackenzie Delta.
Specific activities for this field season include the following:
(1) Improved information on the detailed topography of the Mackenzie Delta floodplain and how delta water levels a...

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. Licenced Year(s):
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...
Principal Investigator:Mielko, Corrinne Licenced Year(s):
Lakes and wetlands in the Canadian Shield have important storage effects that greatly modify runoff generation from the basins. The project objective is to understand and quantify the hydrological processes operating at the basin scale in a boreal Shelf...
Principal Investigator:Jalkotzy, Peter Licenced Year(s):
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 Licenced Year(s):
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 ...

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...

This long term study is being conducted to assist in understanding the factors controlling water levels and the availability of nutrients in a variety of lakes in the Mackenzie Delta....
Principal Investigator:McCart, Peter Licenced Year(s):
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....
