NASA scientists are closely tracking iceberg A-23A as vivid blue meltwater pools spread across its surface, signalling rapid decay. Once covering nearly 4,000 square kilometres, the Antarctic megaberg has shrunk to about 1,180 square kilometres and is fragmenting in warmer South Atlantic waters, offering valuable insight into how rising temperatures accelerate iceberg…​NASA scientists are closely tracking iceberg A-23A as vivid blue meltwater pools spread across its surface, signalling rapid decay.
