World's largest iceberg A23a moves again after months of being trapped

The world's largest iceberg, A23a, is moving again after being trapped in a vortex for months. This follows its release from the seafloor in 2023, where it had been stuck for 37 years. A23a, which is three times the size of New York City, broke free from a Taylor column on December 13. Scientists are monitoring its journey to study the potential impact on the local ecosystem. Researchers are collecting water samples along A23a's path to understand how large icebergs affect ocean life. They aim to learn more about the nutrients these icebergs provide to surrounding waters.
