New satellite images reveal that the iceberg A-68A rotated clockwise, bringing one end of San Pedro Island closer to the South Georgia Archipelago and in shallow water. In the rotation, the iceberg suffered the detachment of one of its ends, by which It is no longer the largest in the world.
The huge block of ice could have scratched the seabed, who in the region has less than 200 meters deep. This would have caused the rupture of its northern point and detached from the northern tip of the iceberg a huge chunk of ice about 18 km long and about 140 square km. The new iceberg detached from the A-68A can be seen on Sentinel 1 satellite images.
he the main iceberg A-68A now measures approximately 3,700 square kilometers and a length of approximately 135 kilometers. Having lost many more chunks of ice in recent weeks, the iceberg has lost its title as the world’s largest. At the first step of the podium of the greatest, he now passes the iceberg A-23A, who is currently stuck in the Weddel Seal, with a size of nearly 4000 square kilometers.
Again it is not known where the iceberg A-68A will travel now and whether or not it will have an impact on the islands of the South Atlantic, which could lead to an ecological disaster. Carried by the currents, it could continue its trek around South Georgia Island like many other icebergs before it in the past, moving southeast, before turning north.
During its first two years of drifting from its source on an ice front attached to the Antarctic Peninsula, the A-68 drifted slowly, hampered by sea ice. But as it moved through the waters relatively free, the pace of the iceberg has increased.
