Sentinel-1A EW SAR images on (left) July 22 2017 and (right) July 5 2018 overlaid,
with LIMA image, showing the changes in area of Iceberg A-68.
The area of Iceberg A-68, calved from Larsen C Ice Shelf in July 2017, was about 5,840 square kilometers. In this project, changes in the area of Iceberg A-68 have been observed over a year. As of July 2018, the area of the iceberg was reduced approximately to 5,650 square kilometers.
The area of Iceberg A-68 was reduced immediately after the separation from Larsen C Ice Shelf and in May 2018. The reason is that a part of the iceberg is separated by cracks. The area of the chunk separated from Iceberg A-68 in May 2018 was approximately 100 square kilometers.
The area of Iceberg A-68 has not changed significantly during the year. However, since many cracks are observed on the iceberg surface, sudden changes in the area may occur in the future.
