Beached iceberg helps reveal ecological impact of sea-ice changes

This item was filled under Climate
The grounding of a giant iceberg in Antarctica has provided a unique real-life experiment that has revealed the vulnerability of marine ecosystems to sudden changes in sea-ice cover. Scientists have found that within just three years of the iceberg becoming stuck in Commonwealth Bay -- an event which dramatically increased sea-ice cover in the bay -- almost all of the seaweed on the sea floor had decomposed, or become discolored or bleached due to lack of light....
