The next image is from 5 March, with thousands of sliver icebergs and a large light blue area of very finely divided bergy bits where the shelf formerly lay. Brownish streaks within the floating chunks mark areas where rocks and morainal debris are exposed from the former underside and interior of the shelf.    The next image is from 5 March, with thousands of sliver icebergs and a large light blue area of very finely divided bergy bits where the shelf formerly lay.

The last image is from 7 March, with thousands of sliver icebergs and a large light blue area of very finely divided bergy bits where the shelf formerly lay. Brownish streaks within the floating chunks mark areas where rocks and morainal debris are exposed from the former underside and interior of the shelf. The last phases of the retreat totalled approximately 2600 square km.    The last image is from 7 March, with thousands of sliver icebergs and a large light blue area of very finely divided bergy bits where the shelf formerly lay.
