  Insights into the impact of melting mega-brergs with robotic gliders

  

  For the first time, scientists have collected measurements close to a giant iceberg, giving an unprecedented window into the impact of meltwater on the surrounding Southern Ocean and ecosystem. The paper is published in the journal Nature Geoscience.

  The drifting giant A68 iceberg released billions of tons of fresh water in South Georgia ecosystem

  

  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.

  A68a iceberg heading for South Georgia shifts direction and loses a chunk of mass

  

  Strong currents have taken hold of a massive Antarctic iceberg that is on a collision course towards South Georgia Island, causing it to shift direction and lose a major chunk of mass, a scientist tracking its journey said on Friday.
