The goal of the article is to track down the giant tabular iceberg D28 trajectory from its calving in September 2019 from Amery Ice Shelf until reaching the western part of the Weddell Sea in March 2023 and to present characteristics of the iceberg state and movement, derived from satellite radar data. The Maximally Stable Extremal Regions (MSER) method, which used as an imagery recognition technique for time-dependent visual conditions, has been applied to automatically identify iceberg’s positions. On the basis of the Sentinel-1A/B SAR data during 1,275 days, timeseries of D28 location, spatial orientation, mass, area, moment of inertia, linear and angular velocity, kinetic and rotational energy, grounding location are presented. D28 dynamics display strongly pronounced regionality, generalized into the three distinct sections of its drift along the Antarctic coast. These sections are in good agreement with existent concepts in the oceanographic literature, concerning the system of Antarctic Slope Current / Antarctic Slope Front.
