Objective(s): The purpose of this research is to gain a better understanding of the origin, distribution properties of massive ground ice in the Mackenzie Delta. Knowing the size and shape of these bodies is one of the keys to determining how they form and how they will respond to climate change or terrain disturbance. The project would involve studying several sites where massive ground ice is present. The aim of the research is to develop techniques for identifying the presence of massive ground ice, delineating the size of ice bodies, and detecting the initial stages of ground ice melt (before landslides develop). We would be using a combination of data from satellite images, ground penetrating radar surveys, and small field samples.

We would be using a combination of data from satellite images, ground penetrating radar surveys, and small field samples. The researcher and an assistant will be based out of the Inuvik Research Centre Lab and will fly via helicopter to two sites in the Mackenzie Delta; Yaya Lake and Peninsula Point. At each site ground penetrating radar surveys will be done to delineate the size of the massive ice bodies and if ice is exposed, collect a small sample (less than 5 l). The data collection at each site is anticipated to take two days.
