Abstract 

Ice velocity determination is an important part of glacier monitoring. This information helps to understand the glacier dynamics as well as its contribution to climatic change. In this article we apply the tracking features/points method of Sentinel-1 data processing. The focus area of this study is Wiggins Glacier. It flowing over 10 nautical miles (18 km) on Kyiv Peninsula in West Antarctica. The offset tracking processing performs using Sentinel-1A IW GRD (Ground Range Detected) images with HH & HV polarization. In this article we show the results of  processed 47 radar images. The initial results of the study of the ice velocity of the Wiggins Glacier, which consisted of 47 velocity maps for the period May 2015 – March 2017, gave several results. We indicate periods of time with lowest, highest value and calculate average ice speed flow: the highest value – 3.83 m/day (05 November 2016); the lowest value – 2.631 m/day (31 August 2015). The average velocity during researching period of time – 3.206 m/day.
