Figure 5: Retreating Margin of the Larsen B Ice Shelf. Colored lines show the retreating margin of the Larsen B ice shelf from 1998 through 2002. The red squares indicate glacier velocity measurement sites where speed increased significantly in the 12 months following the 2002 ice shelf breakup—up to a five-fold flux increase in some places. Measurements at sites indicated by the blue squares showed no large velocity changes. The 1 November 2003 base image is from MODIS Terra. Credit: T. Scambos, NOAA/National Snow and Ice Data Center.
