New study unravels long-standing climate mystery and provides insight into how our planet may change in the future. Scientists claim to have found the “missing link” in the process that leads to an ice age on Earth. Melting icebergs in the Antarctic are the key, say the team from Cardiff […]

January 11, 2020. (Click here for high-resolution view.) Seawater has been cutting like a knife through A-68A, the enormous Antarctic iceberg drifting in the southern Atlantic Ocean. On January 11, 2021, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-20 satellite acquired this image showing the remainder of A-68A, […]

The berg is a little over 130km in length. The small broken chunk is just visible through the cloud COPERNICUS DATA (2020) PIERRE MARKUSE The icy colossus that is A68a has knocked off a corner, seemingly as a result of striking the seafloor. The 3,800-sq-km iceberg, which has been bearing […]

The giant A-68A iceberg could strike land this month – wreaking havoc near the waters of the South Georgia Island. Since its ‘birth’ in 2017, the iceberg has traveled thousands of kilometers from the Larsen C ice shelf, in Antarctica, and now lies around 120 km from South Georgia. If […]

Robotic gliders will be used to gather measurements under and around the iceberg DAVID WHITE A team of scientists is being sent to the South Atlantic to study the giant iceberg A68a. The 3,900-sq-km behemoth is currently drifting offshore of the British Overseas Territory of South Georgia where it threatens to run […]

A massive iceberg named A-68A is on a long journey through the seas near Antarctica. Though largely empty, those waters do host some islands, most notably South Georgia Island. In recent weeks satellite images showed the iceberg heading right for South Georgia. That upcoming collision could have devastating consequences for […]

Over the last three years, satellite missions such as Copernicus Sentinel-1 have been used to track the massive iceberg as it has drifted in the Southern Ocean. This map includes historic iceberg tracks, based on data from a number of satellites including ESA’s ERS-1 and ERS-2 as part of the […]

A-68 has now dropped a large chunk of ice itself. The main berg is about 150km long COPERNICUS/ESA/SENTINEL-1 The world’s biggest iceberg, A-68, just got a little smaller. At around 5,100 sq km, the behemoth has been the largest free-floating block of ice in Antarctica since it broke away from […]
