"British research ship's lucky encounter with world's largest iceberg as it drifts out of Antarctica"

The British polar research ship, RRS Sir David Attenborough, has encountered the world's largest iceberg, A23a, as it drifts out of Antarctic waters. The ship was able to collect seawater samples around the colossal iceberg, which had been grounded for over three decades before recently beginning to drift. The iceberg is now expected to be swept along into "iceberg alley" towards the sub-Antarctic island of South Georgia. Scientists onboard are studying the impact of icebergs on carbon in the ocean and how they contribute to thriving ecosystems. The research findings will help improve understanding of climate change's effects on the Southern Ocean and its organisms.
