Permafrost-active layer dynamics and feedbacks with climate forcing in ice-rich sediments, Fosheim Peninsula, Ellesmere Island, Nunavut (current ongoing PhD thesis)
My research is located within the Fosheim Peninsula on Ellesmere Island in the vicinity of the Eureka Weather Station. This area has a polar desert climate with a mean annual air temperature of -19°C and less than 100 mm of annual precipitation. The area is underlain by approximately 600 m of ice-rich permafrost made up of ice wedges, massive ground ice and fine-grained marine sediments. The area is very sensitive to warming air temperatures as landscape changes arise from thawing permafrost. The main goal of my research is to quantify and explain permafrost and landscape-scale responses in high Arctic polar desert systems within the context of a changing climate.
The geomorphology of two-hypersaline springs in the Canadian High Arctic (M.Sc thesis)
My M.Sc thesis characterised the geomorphology and geochemistry of two hyper-saline spring sites on Axel Heiberg Island, Nunavut. These sites are interesting for many reasons: (1) the amount of salt in the water allows water to flow year round despite a mean annual air temperature of -20°C; (2) large scale salt deposits form that are morphologically similar to deposits known as tufas and travertines. An important distinction between these types of deposits is the mineralogy: travertines and tufas are composed of carbonate minerals but the two deposits I study are made of salt. (3) Finally, these sites are good analogues for groundwater activity on Mars.
I am also interested in sustainability and have been active as organizer and researcher for the annual student-led McGill Sustainability Research Symposium since fall 2013. The symposium brings together student and faculty from around Montreal to showcase sustainability research and to share ideas /discuss sustainability challenges and solutions we are facing today.
