Fox Glacier Photogrammetric Survey – Used a senseFly eBee fixed-wing UAV system to perform aerial photographic survey of the Fox and Sverdrup glacier confluence, on Devon Island, Nunavut. Resulting imagery was post-processed using “structure from motion” methods to produce a 3D point cloud, a high resolution Digital Surface Model (DSM) and orthomasaic image of the scene with 3cm/pixel resolution. This dataset will be used to analyze the complex ice dynamics in this region, the formation of a unique layered ice system, and the formation of surface drainage systems.
Arctic Island Crustal Uplift Monitoring. Studied the methods and processing techniques used to monitor regional ice mass changes. Constructed and installed 4 high-precision GPS monitoring stations on bedrock sites off the edges of the Devon Ice Cap, Nunavut, initiating the first such regional ice mass change monitoring program in Canada. Two additional systems were installed in Quttinirpaaq National Park on northern Ellesmere Island, Nunavut, in 2016 with more installations planned for 2017 – part of an ongoing study of the Lake Hazen watershed. Long term records from these stations will be validated with satellite gravimetry and satellite laser altimetry measurements.
Glacier Monitoring and Instrumentation Projects. Deployed a network of high-precision GPS instruments on moving glaciers in remote areas of the Canadian High Arctic. The data collected allowed him to measure ice flow rates in different zones of these glaciers with high accuracy (<5 cm) and temporal resolution (5 minute) for over seven years. Weather stations and automated temperature and humidity loggers were also deployed to monitor rates of snow accumulation and seasonal melt to relate ice movement to hydrological forcings.
