After being grounded on the ocean floor for over 40 years, the #A23a iceberg in the world is now free.

This is a combination of @CopernicusEU #Sentinel1 images showing how the iceberg rotated/travelled between 2 Nov 2023 (blue) and 26 Nov 2023 (red):esa.int/ESA_Multimedia/Image…

True Color RGB images from @NOAASatellites #GOES16/#GOESEast showed the gradual east-northeastward drift of #Iceberg #A23a, away from Joinville Island at the tip of the Antarctic Peninsula, during the first 11 days of December 2023 (days with thick cloud cover were omitted).

This @CopernicusEU #Sentinel3 image shows iceberg #A23a, currently the largest in the world. #A23a calved from the Filchner-Ronne ice shelf in West Antarctica in 1986, but only started to drift away from Antarctic waters recently, driven by winds and currents.

a FRESH update on the #A23a iceberg journey 🧊🗺️

Similar to many icebergs originating from the Weddell sector, A23a is likely to be expelled into the Antarctic Circumpolar Current – propelling it towards the South Atlantic along a trajectory commonly referred to as ‘iceberg alley’.
This animation uses sea-ice concentration data and shows the iceberg’s movements between 1 November 2023 to 23 January 2024.

True Color RGB images from @NOAASatellites #GOES16/#GOESEast showed #iceberg #A23a during 6 of the minimally-cloudy days so far in February - it appeared to be rotating as it slowly drifted SW toward the South Orkney Islands in the Southern Ocean.

Today's #SatelliteSnapshot shows the month-long journey of the world’s largest iceberg– #A23a.

@NOAA's JPSS satellites watched as A23a wandered Antarctica's Weddell Sea throughout February 2024.

This is what the world's largest #iceberg looks like from geostationary orbit!

@NOAA's #GOESEast (#GOES16) 🛰️ has been tracking iceberg #A23a as it travels through the Southern Ocean, posing a potential threat to the penguins and seals of South Georgia Island.

RT @USGS_EROS: #A23a, the world's largest #Iceberg, began its journey in 1986 when it calved from Antarctica's #FilchnerIceShelf. It remained grounded for the next three decades, but in 2020, it detached and began drifting north. Watch the full video here: https://t.co/HTFwTi82kX
