Supergiant iceberg makes surrounding ocean surface colder and less salty
Read more of: Supergiant iceberg makes surrounding ocean surface colder and less saltyThe melting of the supergiant iceberg A-68 had a huge impact on the ocean around South Georgia, in sub-Antarctica, and significantly changed the Southern Ocean’s temperature and saltiness, with potentially major consequences for this ecologically significant region.

Brunt Ice Shelf speeds up after calving of giant iceberg
Read more of: Brunt Ice Shelf speeds up after calving of giant icebergFollowing the calving of the A-81 iceberg at the end of January 2023, the Brunt Ice Shelf is moving faster than before. It is currently moving approximately 4 metres a day towards the sea, whereas before the calving it moved at an average of between 1-2.5 metres a day.
