Learning Points
- The world’s largest iceberg, A23a, has run aground near the island of South Georgia.
- Icebergs form when large chunks of ice break off glaciers or ice sheets, a process known as calving.
- As A23a iceberg melts, it will release nutrients into the ocean, which could increase food for the whole food chain.
