World’s Largest Iceberg Threatens South Georgia Wildlife

The world’s largest iceberg, A23a, is drifting towards South Georgia, posing a potential threat to local penguin and seal populations, The Guardian reported. Measuring over 3,500 sq km, the iceberg is moving from Antarctica at a slow pace, with scientists predicting it could reach the island’s shallow continental shelf in two to four weeks.

Andrew Meijers, a physical oceanographer, noted that unlike previous icebergs, A23a is not breaking apart, making its exact trajectory uncertain. It could either run aground, disrupting wildlife feeding grounds, or drift into open water. If grounded, it could impede seals and penguins as they forage for food during the summer breeding season.

The region is already experiencing challenges, including a bird flu outbreak among wildlife. As A23a melts, it will release nutrients into the ocean, potentially benefiting marine ecosystems but also creating navigational hazards for fishermen. Scientists are closely monitoring the iceberg’s path as it continues its journey northward.
