Over the last 3 years, satellite objectives such as Copernicus Sentinel-1 have actually been utilized to track the enormous iceberg as it has actually wandered in the Southern Ocean. This map consists of historical iceberg tracks, based upon information from a variety of satellites consisting of ESA’s ERS-1 and ERS-2 as part of the Antarctic Iceberg Tracking Database, and reveals that A-68A is following this well-trodden course.

The colossus iceberg that divided from Antarctica’s Larsen C ice rack on July 12, 2017, is on a clash with South Georgia.

Over the last 3 years, satellite objectives such as Copernicus Sentinel-1 have actually been utilized to track the berg as it has actually wandered in the Southern Ocean. For the very first 2 years, it stayed near to its moms and dad ice sheet, hampered by sea ice. But now, as the map reveals, the primary piece of the A-68 berg, referred to as A-68A, is heading quickly for South Georgia. It is now about 350 km from the island.

About the very same size as the South Atlantic island, it might ground in the shallow waters offshore and trigger genuine issues for the island wildlife and seafloor-dwelling life. Penguins and seals require access to the sea to feed so the iceberg might quickly obstruct their foraging paths and life on the seafloor might be squashed if the berg premises. The worry is that if the berg does anchor versus the South Georgia coast, it might stay there for as much as 10 years. When the A38 grounded here in 2004, lots of dead penguin chicks and seal puppies were discovered along the coastline.

The map consists of historical iceberg tracks, based upon information from a variety of satellites consisting of ESA’s ERS-1 and ERS-2 as part of the Antarctic Iceberg Tracking Database, and reveals that A-68A is following this well-trodden course. Hopefully, currents will take A-68A around South Georgia and off to the northwest, and ultimately separate.
