Title: Copernicus Sentinel-1 continues following the iceberg's voyage
Description: On 11 June the drift turned about towards NE and then on 12 June more or less into NNW direction. This course continued until 14 June, when it shifted again east-ward. This direction was tracked so far by three additional Sentinel-1 SAR images until 20 June. Within this period the drift velocity varied between approximately 0.4 and 0.8 knots.
The drift of icebergs is related to the interaction between surface winds and currents. Therefore, Professor Klaus Strübing thinks it would be of interest to investigate the reasons for the distinct and abrupt changes in the drift directions of the unnamed iceberg. Strübing feels they are subject to some oscillations within the northern part of the Weddell Gyre influenced by stronger surface winds.
