CREATION OF GLACIERS VELOCITY MAPS IN LIVINGSTON ISLAND USING SENTINEL-1 DATA

Livingston Island is an Antarctic island in the Southern Ocean, part of the South Shetlands Archipelago. The Bulgarian base "St. Kliment Ohridski" is located on the Hurd Peninsula some 130 m from the shores of the inner bay Emona. In this study we use data from the Sentinel-1 satellite constellation to produce velocity maps, covering few key outlet glaciers. During this research used were Sentinel-1 data in GRD format with HH polarisation. We followed the processing workflow described by international scientific community to derive ice velocity maps from pairs of SAR images using the SNAP software. In this paper are presented results for glaciers found in Livingston Island and the ice velocity extracted along the two flow line transects/longitudinal and transverse profiles. This study provides a first demonstration by authors of the operational radar satellites capacity to map and thus providing frequent and timely monitoring of the ice sheet flow as well as to monitor the dynamic evolution of the glaciers around the Bulgarian base "St. Kliment Ohridski"
