A crack on the Antarctic ice shelf grew dramatically in late 2020 into 2021. Scientists are watching to see if the rapidly accelerating crack will cause the shelf to rip apart before Antarctica’s sunlit summer season – going on now – comes to an end.
NASA’s Landsat 8 satellite acquired this image of the Brunt Ice Shelf on January 12, 2021. The ice flows away from the Antarctic mainland and floats on the eastern Weddell Sea. The main shelf area has long been home to the British Antarctic Survey’s Halley Research Station, from which scientists study Earth, atmospheric, and space weather processes. Image via NASA/ USGS.
