Supplementary Information:


Changes of Larsen Ice Shelf, Antarctica, and the surrounding glaciers after its collapse in 1995 were investigated using satellite radar imagery, with emphasis onchanges in the glaciers which previously nourished the ice shelf north of Seal Nunataks. The large glaciers retreated several kilometres inland of the previousgrounding line. The velocity field of Drygalski Glacier, the largest glacier in this area, was mapped by means of interferograms derived from pairs of ERS syntheticaperture radar images from 1995 and 1999. The main part of the glacier showed significant acceleration of flow over these 4 years, with an increase of veocity upto three-fold at the terminus. Similar accelerations were observed by means of interferometry on several other grounded glaciers, suggesting that the removal ofice shelves could lead to an effect on eustatic sea level. For Larsen B, the northernmost surviving part of Larsen Ice Shelf, the retreat of the ice front to October2000 is documented.
