On the time evolution of the d'Iberville glacier using C-band SAR data

Monitoring the polar regions is of outmost importance for climatological studies. Human-induced climate change is leading to global warming, which, among other effects, is causing glaciers' melting. This has significant implications for sea level rise and ocean circulation. This study focuses on the temporal analysis of the d'Iberville glacier ice edge using C-band synthetic aperture radar satellite imagery. First, the profile of the d'Iberville glacier is extracted from synthetic aperture radar imagery. To accomplish this task, an unsupervised method based on a global threshold constant false alarm rate approach is applied to the HH-polarized normalized radar cross section measurements. Then, the ice edge variability is quantified using two Sentinel-1 synthetic aperture radar images acquired in 2015 and 2022. The experimental results show that the d'Iberville glacier experienced a remarkable retreat of about one square kilometer from 2015 to 2022.
