Summary: The main objective of this study is to establish the degree of impact and spatial extent of specific oceanic storm surges within the coastal Mackenzie Delta over the past 40 years. This investigation will be completed by analyzing remote sensing imagery to create multiyear change maps. The resulting maps will then be correlated to historic water level and climate data and verified by field samples...

Summary: The main aim of these weather and air quality studies is to improve the understanding of the processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. The aim of the sea ice studies is to obtain a snapshot of ice thickness in a vast region of the Arctic, and to create an inventory of Arctic sea ice volume. ...

Summary: The objective of this research is to measure high and low voltage patterns hundreds of kilometers above the ground and out into space along the Earth's magnetic field lines. This information is critical to personnel in space and to maintenance of the satellite telecommunications. Radar transmitting and receiving electronics will be installed in a small building with an antenna array outside. A ...

Summary: The objective of this study is to develop a hydro-ecological model for small Arctic lakes to assess the vulnerability of their ecosystems to disturbances, such as climate change or water withdrawal. To quantify geochemical loadings to lakes, a model is being developed by monitoring lakes and their contributing catchment (surface water flow). A climate station will be set up at 2 - 6 sites to mo...

Summary: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...

Summary: The objectives of this study are to quantify the frequency and magnitude of ice jams in the Mackenzie River Delta, including the hydroclimatic conditions controlling their occurrence and associated floods, develop a hydraulic model of it, and investigate the importance of deep scour holes in the Mackenzie River. This study is an expansion of previous research conducted in 2004. Ice jamming has ...

Summary: The main goal of this research is to use lake sediment records to examine changes in weather conditions and river discharge in the western Canadian Arctic during the past 2000 years, which will aid in understanding current conditions and forecasting future conditions. The research team will reach the study location by airplane from Resolute, Nunavut, and will be on site from late May to early ...
