Being one of the largest icebergs ever known, it was almost two times bigger than Luxembourg when it decided to leave its motherland and gave the Antarctic Peninsula a complete new frame, compares ESA. Monitored by Copernicus Sentinel-1 mission for the last three years, the berg has covered a long distance. Compared to its huge surface, the thickness appears to be quite thin with a few hundred meters thick.
After the berg separated its way from home, it couldn’t stop losing piece after piece. Recently it has lost its third chunk called A-68C in April 2020, which came after A-68B. The logic behind the naming process of icebergs performs as where they were seen first. A sequential number is added. If the berg calves, a sequencing number comes later. Consequently, A-68 was renamed as A-68A after losing its first part, explains The European Space Agency.
It’s been three years since the berg is swimming on its own and being monitored by Copernicus Sentinel-1 mission. In 2020, it started to move away from the icecap towards the South Atlantic.
The map above displays how far A-68A has gone after it lost its two big pieces in the last three years. The berg had kept its distance close to Larsen C during 2018 and 2019, while it speeded up in 2020. The most recent position A-68A taken was monitored on the 5th of July by Copernicus Sentinel-1 mission.
