The eastern Weddell Sea region is an alley for drifting icebergs, which calve further east along the coastline of East Antarctica. Our analysis is focused on the region north of the Ekstr¨om Ice Shelf. Since at the Ekstr¨om Ice Shelf a landing place is used for the supply of the Ger- man overwintering station Neumayer III and the South- African station Sanae IV, it is important to monitor the drifting routes taken by the icebergs in this region. We use a series of ENVISAT ASAR WSM data to follow a larger (D18) and a smaller (IB1) iceberg through the east- ern Weddell Sea region in 2006. Model simulations are carried out to get more detailed information about the rel- ative influence of different forces on the iceberg drift in this region.
