Investigation of Grounding Line Dynamics and Thinning of Milne Glacier, Nunavut Using In-situ and Satellite Data
Posted 6 years ago
By Yulia Antropova
The line where glaciers transition from grounded to floating is particularly susceptible to changes caused by warming in the Arctic. Grounding line retreat is associated with ice thickness reduction and enhanced ice discharge. Milne Glacier, located on Ellesmere Island, Nunavut (Fig. 1), is a surge-type glacier [1]. Its bed is on a retrograde slope, therefore, […]

Monitoring of snow cover area in the Apex river watershed in Nunavut, Canada at different temporal and spatial scales is important to better understand and predict freshwater resource supply in that area. My previous post describes retrieval of changes in the snow-cover for a large area using MODIS 8-day composite snow cover products with a spatial resolution […]

As a part of Directed Studies in Geomatics course supervised by Dr. Murray Richardson at Carleton University I developed a tool that allows a user to easily produce time-series plots of snow-cover area and other relevant pieces of information (e.g. bare ground, cloud, and night cover) for any region (defined by an input shape file) […]

Here I would like to discuss creation of maps in ArcMap using different mapping techniques. In particular I was able to easily create the following maps as a part of an assignment for GEOM3007 course: dot density map (shown in Figure 1), proportional symbol map (shown in Figure 2), and choropleth map (shown in Figure […]

I took Geospatial analysis course in Fall 2016 term which guided us through different ArcMap tools useful for digital spatial data analysis. For my final project I choose to explore tools in ArcMap for processing data acquired by Lidar technologies. UAV-mounted Lidar technologies provide measurements of the distance between the UAV and the target which […]
