<P> The Larsen D Ice Shelf is between Smith Peninsula in the south and Gipps Ice Rise . It is considered to be generally stable . Over roughly the past fifty years it has advanced (expanded) whereas comparable George VI, Bach, Stange, and Larsen C ice shelves have retreated (to a much greater net extent). The most recent survey of Larsen D measured it at 22,600 km . There is fast ice along the entire front . This makes it difficult to interpret the ice front because the semi-permanent sea ice varies in thickness and may be nearly indistinguishable from shelf ice . </P> <Ul> <Li> <P> Larsen A and Larsen B ice shelves marked in red . </P> </Li> <Li> <P> Clear view of the Antarctic Peninsula, the Larsen Ice Shelf, and the sea ice covered waters around the region . </P> </Li> <Li> <P> Larsen B area in March 2013 </P> </Li> <Li> <P> 2016 rift in Larsen C, detail </P> </Li> <Li> <P> Imagery from NASA's Aqua MODIS showing the complete break of the ice shelf as of 12 July 2017 </P> </Li> <Li> <P> Radar imagery from ESA's Sentinel - 1B taken on 12 July 2017, showing the complete break </P> </Li> </Ul> <Li> <P> Larsen A and Larsen B ice shelves marked in red . </P> </Li> <P> Larsen A and Larsen B ice shelves marked in red . </P>
