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.
