It’s unknown what impact the release of 152 billion tonnes of fresh water near an island like South Georgia will be. The amount of water released from the melting iceberg could have far reaching consequences. “Frequent measurements allowed us to follow every move and break-up of the berg as it moved slowly northwards through iceberg alley and into the Scotia Sea where it then gained speed and approached the island of South Georgia very closely.“ ![]() “A68 was an absolutely fascinating iceberg to track all the way from its creation to its end,” said Laura Gerrish, GIS and mapping specialist at BAS. The British Antarctic Survey (BAS) monitored the berg’s location, and how it’s area and thickness changed over time via satellite technology. In July 2017, the iceberg broke off the Larsen-C Ice Shelf on the Antarctic Peninsula and began an incredible 4,000 kilometer journey across the Southern Ocean over threw and a half years. A new study has revealed that the equivalent of 61 million olympic-sized pools of fresh water were released into the seas near South Georgia when “mega” iceberg A68A melted over three months from 2020 to 2021. ![]()
