The white area to its left may be the result of what Shuman described as a \u201cblowout.\u201d The weight of the water pooling at the top of the towering iceberg would have created enough pressure at the edges to punch through. The blowout may have allowed meltwater to spill tens of meters down to the ocean surface in what researchers call a \u201cfreshwater discharge plume,\u201d where it mixed with the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Ice_m%C3%A9lange\" rel=\"noopener\">m\u00e9lange<\/a> of ice bits floating next to the iceberg.<\/p>\n<p>Scientists say these signs indicate the iceberg could be just days or weeks from disintegrating completely. \u201cI certainly don\u2019t expect A-23A to last through the austral summer,\u201d said Shuman, noting that the season typically brings clearer skies and warmer air and water temperatures\u2014factors that accelerate the disintegration process in an area known among ice experts as a \u201cgraveyard\u201d for icebergs. It\u2019s already in water that\u2019s about 3 degrees Celsius and riding currents that are pushing it toward even warmer waters that will eat away at it quickly, added Meier.<\/p>\n<p>Even by Antarctic standards, A-23A has had a long, winding journey full of unexpected chapters that have improved scientists\u2019 understanding of the \u201cmegabergs\u201d occasionally released into the Southern Ocean. After grounding in the shallow waters of the Weddell Sea for more than 30 years, A-23A broke free in 2020, then spent several months in a <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/antarctic-iceberg-spins-out-153727\/\" rel=\"noopener\">twirling ocean vortex<\/a> called a Taylor column. It eventually <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/antarctic-iceberg-spins-out-153727\/\" rel=\"noopener\">spun away<\/a> and headed north, <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/iceberg-grinds-to-a-stop-off-south-georgia-island-154022\/\" rel=\"noopener\">nearly colliding<\/a> with South Georgia island and <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/antarctic-iceberg-loses-its-edge-154262\/\" rel=\"noopener\">lodging in shallow waters<\/a> for several months before escaping into the open ocean, where it has been <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/a-giant-icebergs-final-drift-154827\/\" rel=\"noopener\">rapidly breaking apart<\/a> throughout 2025.<\/p>\n<p>Scientists who have been tracking the berg for their entire careers see its imminent demise as a bittersweet moment. \u201cI\u2019m incredibly grateful that we\u2019ve had the satellite resources in place that have allowed us to track it and document its evolution so closely,\u201d said Shuman. \u201cA-23A faces the same fate as other Antarctic bergs, but its path has been remarkably long and eventful. It\u2019s hard to believe it won\u2019t be with us much longer.\u201d<\/p>\n<p>Even as A-23A fades, other massive bergs are parked or drifting along the Antarctic shoreline. Several, including A-81, B22A, and D15A, are each larger than 1,500 square kilometers and sit waiting for their moment to break free and begin their journey north.<\/p>\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<p><em>NASA Earth Observatory image by Michala Garrison, using MODIS data from NASA <a href=\"https:\/\/www.earthdata.nasa.gov\/data\/projects\/lance\" rel=\"noopener\">EOSDIS LANCE<\/a> and <a href=\"https:\/\/worldview.earthdata.nasa.gov\/\" rel=\"noopener\">GIBS\/Worldview.<\/a> ISS Astronaut photograph <a href=\"https:\/\/eol.jsc.nasa.gov\/SearchPhotos\/photo.pl?mission=ISS074&#038;roll=E&#038;%23038;frame=8943\" rel=\"noopener\">ISS074-E-8943<\/a> was acquired on December 27, 2025, with a Nikon Z 9 digital camera using a focal length of 500 millimeters.
