Scientists have been keeping a close eye on the 'megaberg' designated as A68a since it split off from Antarctica back in July 2017 – and new research highlights just how much freshwater it's released into the ocean during its late melting proces
Scientists monitoring the giant A68a iceberg from space reveal that a huge amount of freshwater was released as it melted around the sub-Antarctic island of South Georgia. An estimated 152 billion tons of freshwater – equivalent to 20 x Loch Ness or 61 million Olympic sized swimming pools, entered the seas around the sub-Antarctic island of South Georgia when A68a melted over three months in 2020/2021, according to a new study published this month by the British Antarctic Survey.
According to recent research, the megaberg A68A melted over three months in 2020/2021, releasing 152 billion tons of fresh water into the oceans around the sub-Antarctic island of South Georgia, equivalent to 20 times the volume of Loch Ness or 61 million Olympic-sized swimming pools.
