Iceberg B-22a was formed in 2001, when it calved from the ice shelf formed by the Thwaites glacier in West Antarctica and started floating in the Amundsen Sea.

Summary

[edit]
Description
English: Iceberg B-22a was formed in 2001, when it calved from the ice shelf formed by the Thwaites glacier in West Antarctica and started floating in the Amundsen Sea. In 2022 and 2023, it started moving towards the northwest and drifted by about 112 kilometres, 21 of which were covered between December 2022 and January 2023. This image was acquired by one of the Copernicus Sentinel-3 satellites on 18 January 2023. Previously acquired Copernicus Sentinel-3 images were used to trace and track Iceberg B-22a: its perimeter and position have been projected from past Copernicus Sentinel-3 acquisitions onto the latest image, to visualise the movement of the iceberg. The location of the iceberg on 11 October 2016 is indicated red, in blue its location on 25 December 2022, and finally in green its location on 18 January 2022. Copernicus open data are key for tracking the movement of icebergs floating in the ocean and the monitoring of remote environments such as Antarctica.
